5 Summry The primry gol of the Arknss Cotton Vriety Test is to provide unbised dt regrding the gronomic performnce of cotton vrieties nd dvnced breeding lines in the mjor cotton-growing res of Arknss. This informtion helps seed compnies estblish mrketing strtegies nd ssists producers in choosing vrieties to plnt. These nnul evlutions will then fcilitte the inclusion of new, improved genetic mteril in Arknss cotton production. Adpttion of vrieties is determined by evluting the lines t five University of Arknss System Division of Agriculture reserch sites (Mnil, Keiser, Judd Hill, Mrinn, nd Rohwer). Entries in the 2017 Arknss Cotton Vriety Test were evluted in two groups trnsgenic nd conventionl vrieties. The 41 entries in the trnsgenic test included 18 entries (13 B2XF, 2 WRF, 2 GLT, nd 1 GLB2) returning from the 2016 test nd 23 first-yer entries (6 B2XF, 3 B3XF, 1 GLT, nd 13 W3FE) nd were evluted t ll five loctions. The conventionl test included 16 entries nd ws evluted t ll loctions except Mnil. Reported dt include lint yield, lint percentge, plnt height, percent open bolls, yield component vribles, fiber properties, lef pubescence, stem pubescence, nd brct trichome density. All entries in the experiments were evluted for response to trnished plnt bug nd bcteril blight in seprte tests t Keiser. This 2017 report includes results of lrge-plot vriety tests in 7 counties tht were coordinted by Bill Robertson.

6 Arknss Cotton Vriety Test 2017 F. Bourlnd, W. Brnett, C. Kennedy, L. Mrtin, A. Rouse, nd B. Robertson 1 Introduction T he purpose of the University of Arknss Cotton Vriety Testing Progrm is to provide unbised comprisons of cotton vrieties nd dvnced breeding lines over rnge of environments. Dt from these tests help to identify the potentil dptbility of vrieties to prticulr cotton-growing regions of the stte. Bourlnd et l. (2000) documented severl unintentionl bises, which re inherent to the Arknss cotton vriety testing progrm. These include mngement ssocited with vrieties expressing herbicide nd insect resistnce. The bises tend to cncel ech other so tht no gret dvntge is given to ny prticulr vriety. Since evlution of genetic differences mong entries is the ultimte gol of the evlutions, ll vrieties re treted identiclly within the primry loctions (Mnil, Keiser, Judd Hill, Mrinn, nd Rohwer) of the vriety test. No specilized production inputs were employed with respect to the vrious geneticlly enhnced vrieties. All entries in the tests t Mnil possessed the RF or G genes, nd were uniformly treted with Round-up. Since the plots were over-spryed with Roundup, the conventionl vrieties were not evluted t Mnil. Mterils nd Methods The 41 entries in the trnsgenic test included 18 entries (13 B2XF, 2 WRF, 2 GLT, nd 1 GLB2) returning from the 2016 test nd 23 first-yer entries (6 B2XF, 3 B3XF, 1 GLT, nd 13 W3FE) (Tble 1). The trnsgenic test ws replicted 6 times t Mnil, 5 times t Judd Hill, nd 4 times t Keiser, Mrinn, nd Rohwer. The conventionl test included 16 entries nd ws evluted using 5 replictions t ech loction. Test sites included the Northest Reserch nd Extension Center t Keiser; the Judd Hill Coopertive Reserch Sttion t Judd Hill (ner Trumnn); the Lon Mnn Cotton Reserch Sttion t Mrinn; the Mnil Airport Cotton Reserch Frm t Mnil; nd the Rohwer Reserch Sttion t Rohwer. Culturl prctices nd wether dt (het units nd rinfll) ssocited with the test sites re listed in Tble 2 nd Tble 3, respectively. Origintors of seed supplied double-treted (two fungicides) seed for ll entries. Prior to plnting, ll seed were treted with imidcloprid (Gucho ) t rte of 6 oz/100 lb seed. Plots were plnted with constnt number of seed (bout 4 seed/row ft). All vrieties were plnted in tworow plots on 38-inch centers nd rnged from 40 to 50 feet in length. Experiments were rrnged in rndomized complete block. Although exct inputs vried cross loctions, culturl inputs t ech loction were generlly bsed on University of Arknss System Division of Agriculture Coopertive Extension Service recommendtions for cotton production, including COTMAN rules for insecticide termintion. All plots were mchine-hrvested with 2-row or 4-row cotton pickers modified with lod cells for hrvesting smll plots. Dt Collected t Single Loction Lef Pubescence. Lef pubescence ws visully rted on scle of 1 (smooth lef) to 9 (pilose, very hiry) in the irrigted experiments t Keiser using the system described by Bourlnd et l. (2003). A full-sized minstem lef locted bout 5-6 nodes from plnt pex ws rted for 6 plnts per plot for ll 5 replictions during August. Stem Pubescence. Stem pubescence ws visully rted on scle of 1 (smooth stem) to 9 (very hiry) in the irrigted experiments t Keiser using system similr to tht used for leves. After hrvest, the upper 5-6 inches of the plnt pex ws rted for 6 plnts per plot for ll 5 replictions. Brct Trichomes. As ll plnts pproched physiologicl cutout, brct from 1st position white flower ws smpled from 6 rndom plnts per plot (4 of the 5 replictions) in the Keiser experiments. Ech brct ws exmined for mrginl trichome density (no. of trichomes/ cm) s described by Bourlnd nd Hornbeck (2007). Mens for the 6 brcts were evluted s plot mens. 1 F. Bourlnd is professor, nd W.

7 Arknss Cotton Vriety Test 2017 Trnished Plnt Bug. Entries in both vriety tests were evluted for response to TPB in seprte field t Keiser. The TPB test included 8 replictions of 1-row plots (20-feet long on 38-inch wide rows). Four rows of highly susceptible Frego-brct line were plnted between the tests on April 14. The TPB tests were plnted on My 15 nd received no insecticide tretment for TPB infesttions. Erly flowering in the susceptible Frego-brct strips encourged TPB popultions to increse, then to migrte from the strips s the test plots begn to flower. Response to TPB ws determined by exmining white flowers (6 flowers/plot/dy for 6 dys in lte August) for presence of nther dmge. Accumultive percentge of dmged flowers ( dirty flowers ) ws determined for ech plot. Bcteril Blight. Entries in both tests were plnted in flts (2 replictions, 13 seed/plot) in the greenhouse, nd scrtch inoculted with Xnthomons citri pv. mlvcerum. The inoculum ws obtined from nturlly infected leves collected t the 2015 Mnil loction. Scrtches were exmined for wter-soking, nd percent of susceptible plnts ws determined. Verticillium Wilt. Reltive yields of vrieties over yers t Judd Hill should be indictive of tolernce to Verticillium wilt. Dt Collected t All Loctions Plnt Height. Plnt height mesurements (in cm) were collected fter plnts hd cutout. Averge plnt heights for vrieties were determined by mesuring from the soil surfce to the terminl of one verge-sized plnt in ech of the two rows. Plot mens (verge of the two mesurements) were evluted. Plnt height ws not mesured t Mrinn in % Open Bolls. After first ppliction of defolints, percentge of open bolls ws estimted from the front nd bck of ech plot, then verged for ech plot. Boll Smples nd Lint Percentge. Prior to mechnicl hrvest, hnd-hrvested smples of 40 open bolls were obtined from 2 replictions t ech loction. Within ech row of 2-row plots, site hving verge or bove verge plnt density ws chosen nd 20 bolls (5 bottom, 10 mid-cnopy nd 5 top bolls) were hrvested nd bulked to form 40-boll smple. The 40-boll smples were ginned (lb gin without the use of lint cleners) to determine lint frction (the percentge of lint weight to seed cotton weight). Fiber Properties. Fiber smples were tken from ech boll smple nd were evluted using HVI clssifiction. Prmeters included micronire, fiber length, length uniformity index (UI), strength, nd elongtion. To reflect mrket demnd for fiber qulity, weighted qulity score (Q-score) ws clculted s described by Bourlnd et l. (2010). Prmeters (nd weighting) included in Q-score were fiber length (50%), micronire (25%), length uniformity index (15%), nd strength (10%). Seed Index. Two sets of 25 fuzzy seed from the ginned seed of ech 40-boll smple were counted nd weighed. If the two weights vried more thn 0.2 g, second set of smples ws tken. Two consistent weights of 25 seed were used to clculte fuzzy seed index (weight of 100 seed). Seed Per Acre. For ech plot, n estimte of number of seed per cre ws determined by multiplying seed cotton yield (lb/a converted to g/a) times verge seed percentge (the percentge of seed weight to seed cotton weight in ginned smple, verged by entry nd loction over reps), then divided by verge seed weight (verge seed index by entry over reps divided by 100). Lint Index. Lint index (weight of lint on 100 seed) ws determined from 40-boll smple dt by dividing lint weight from ginned smple by the number of seed per smple (estimted using verge seed weight) then multiplying by 100. Fibers Per Seed. Fibers per seed were estimted by dividing lint index by n estimted weight of individul fibers. Weight of n individul fiber ws estimted by: (fiber length length uniformity (micronire/1,000,000)). Fiber Density. Fiber density, reported s the number of fibers per mm 2, ws estimted by dividing fibers per seed by seed surfce re. Seed surfce re (SSA) ws estimted by the regression eqution suggested by Groves nd Bourlnd (2010): SSA = SI, where SI is equl to seed index ssocited with the smple. Lint Yield. Seed cotton yield per plot (determined by mechnicl cotton picker) ws converted to seed cotton yield per cre then multiplied by verge lint percentge (determined by vriety nd loction) to estimte lint per cre. Yield Comprisons Uncontrolled vrition is inherent to collection of vriety performnce dt (prticulrly yield dt). In ddition to their genetic bility, vrition mong vrieties my be due to slight differences in soil, pest or climtic conditions within field, vrious interctions with specific mngement prctices, or experimentl error. Sttistics llow users to define the degree of uncontrolled vrition nd to in- 5

8 AAES Reserch Series 650 terpret dt. The sttisticl tool used to compre mens in these tests ws Fisher s Protected Lest Significnt Difference (LSD). An LSD ws clculted when the F-test vlue from nlysis of vrince ws significnt. Yields of vrieties re considered significntly different if the difference between men yields of two vrieties is greter thn the LSD vlue. Differences tht re smller thn the LSD my hve occurred by chnce or my be ssocited with uncontrolled vrition, nd re therefore considered not significnt. Additionl estimtes of vrition re provided by mesures of R-squred nd coefficient of vrition (CV). R- squred (times 100) indictes the percentge of vrition tht is explined by defined sources of vrition (e.g., repliction nd vriety effects within loction). Confidence in dt increses s R-squred increses. Generlly, the meningfulness of difference mong mens is questionble when dt hve R-squred vlues of less thn 50%. Also, confidence in dt becomes greter s CV declines. Results Entries nd prticipnts in the test re listed in Tble 1. Culturl inputs nd production informtion for vriety trils t Mnil, Keiser, Judd Hill, Mrinn, nd Rohwer re reported in Tble 2. Tble 3 includes wether informtion for north, centrl, nd south Arknss loctions during the 2017 production seson. The Rohwer loction ws plnted on April 25, but rin delyed plnting t ll other loctions (Tble 2). Monthly het unit ccumultion ws ner norml t Keiser nd Mrinn from My through July, then cooler thn norml in August nd September, nd wrmer thn norml in October (Tble 3). Tempertures t Rohwer were cooler thn norml from My through August, then wrmer thn norml in September nd October. Except for October, rinfll ws higher thn norml through the seson t ech loction. Rinfll in August ws prticulrly high-more thn twice the norml mount t ech loction. Hrvest conditions were optimum t ech loction.

The test t Mnil ws plnted in the sme field used since 2014, nd in the sme re of the field used since In nticiption of high field vribility, the test ws replicted 6 times with 3 tiers used per repliction. The R-squred vlues for lint yield were reltively low, but reltive yield differences mong the vrieties t Mnil were similr to other loctions. Mepiqut chloride (totl of 64 oz/a) ws used to control plnt height. Keiser (Tbles 8, 9, 20 nd 21). To help combt resistnt pigweed, cerel rye cover crop ws plnted to the field in the fll of The cover crop grew well nd ws terminted in mid-april. Unfortuntely, excessive rins nd wind cuse much of the cover crop to bend over, nd delyed drying of soil. We subsequently decided to mow the cover crop nd plnt the tests on My 11 in the residue. Resulting stnds were not s uniform s desired, nd plnts did not grow t n cceptble rte. Pigweeds were hnd-hoed throughout the seson.

The cover crop worked very well in 2016, but nitrogen pplied to the cover crop cused excessive growth in Unfortuntely, the excessive cover ws not killed in timely mnner, nd we hd difficulty plnting the plots. Without GPS formed rows, it ws impossible to sty on top of beds while plnting. The excessive cover mde it difficult to get proper plcement of seed, nd subsequently tied up nitrogen throughout the seson. Results stnds were reltively poor, nd plnts did not develop properly. Mepiqut chloride (totl of 2.5 oz/a) ws used to control plnt height. Rohwer (Tbles 14, 15, 26 nd 27). The Rohwer loction ws plnted on April 25, nd excellent stnds were chieved. The plnts grew well, nd produced good yields. The field ws scheduled to be hrvested in September, but the 4-row plot picker burned just before hrvesting our field. The picker ws completely destroyed nd hd to be replced. Hrvest ws delyed until October 17. Mepiqut chloride (totl of 40 oz/a) ws used to control plnt height. References Bourlnd, F.M., N.R.
