5 INTRODUCTION Cotton performance trials were conducted during 2011 at Lubbock, Halfway, and Pecos, Texas AgriLife Research Stations. The Lamesa variety tests were planted on the AG-CARES research farm. The Lubbock tests were planted in either Amarillo or Olton soils, the Halfway test in Pullman clay loam soils, AG-CARES in Amarillo fine sandy loam, and Pecos tests in Hoban silty clay loam soils. West T exas suffered through its worst drought in recorded history during 2011, and subsequently t he cotton crop r eflected i t. I n t he S outh P lains and P anhandle r egions of Texas approximately 4.61 m illion a cres of c otton w ere planted, of w hich 1.74 m illion a cres w ere harvested. Thus, only 38% of the planted cotton made it to harvest; not a single acre of dryland cotton is thought to have been harvested in Conditions dur ing e arly t o m id-may w ere dr y a nd c ool, a nd c old s oil temperatures deterred m uch pl anting. Incessant w inds qu ickly dri ed the so il. D rip irrigated fields w ere especially hurt by the dry conditions where they could not get moisture up and over to the seed. Most dr ip irrigated fields did not ha ve t he c apabilities t o r ow w ater. I n l ate M ay a nd J une conditions t urned e xtremely hot a nd w indy, f urther exasperating t he dr oughty c onditions. As cotton began to bloom growers had difficulty meeting water demand. E vapotranspiration often exceeded 0.6 -inch p er d ay a nd v ery f ew pi vots w ere a ble to m eet this de mand. C otton i n the Panhandle fared better than on the South Plains simply because of high irrigation capacity. Many growers had to abandon corn which r eleased water for c otton. The dry, hot weather continued into August and although some isolated precipitation did occur, it was too little too late. Because of the abnormally hot weather, the cotton crop received a good amount of heat units w hich resulted i n an ear lier t han normal ha rvest. Quite a f ew ac res w here h arvested in September. A lthough t he c rop w as ha rvested e arlier t han nor mal, i t r eturned l int w ith hi gh micronaire. Yields were negatively impacted by the drought averaging 485 l bs/ac in the South Plains. Areas of the Panhandle with sufficient irrigation capacity did better averaging 569 lbs/ac. Disease and nematode issues were not as serious in 2011 as during most years, simply because the drought. However, nematode tolerant varieties, along with early-season applications of Vydate did result in increased yield in most cases. Glyphosate resistant pi gweeds were confirmed i n the T exas S outh Plains in The extent of the problem is not certain but efforts are underway to mediate and prevent its spread. Early-season thrips p ressure w as l ight t o moderate a cross t he r egion, isolated to small areas. Some areas saw almost no thrips whereas others, sometimes close by, had severe problems. The most prevalent thrips species on the South Plains was easily controlled onion thrips, while the Panhandle saw mixed populations of onion and the more difficult to control, western flower thrips. The only cotton that suffered much damage and yield loss from thrips was that which was planted in early May. Because of the excessive heat the remaining cotton had fewer thrips and was able to outgrow what little damage it suffered. Spider mites were evident upon plant emergence from Midland to Muleshoe, also in the Lubbock a rea a nd s outh, they pr ogressed i nto b loom. O ver 15,000 a cres w ere infested w ith 4

6 mites, about 7,000 of which were treated. Cotton fleahoppers, Lygus and stinkbugs were almost non-existent. A phids w ere c ommon i n m id-july t hrough m id-august, but n ever de veloped treatable populations. Most non -Bt c otton f ailed a long w ith t he d ryland, but s ome L epidopterous p est w ere problematic i n i rrigated n on-bt c otton i n the s outhwestern por tion of the S outh P lains. T hese included bollworms and fall armyworms. Worms were not a problem in any Bt cotton fields. The most severe pest problem experienced in 2011 was Kurtomathrips morrilli. This is a little known thrips that has never been reported damaging cotton in Texas. It was first detected in late-july in Gaines County and it quickly spread as far north as southern Bailey County and east to s outhwestern C rosby C ounty. It i nfested an estimated 330,000 a cres, 83,000 a cres of which were treated with insecticides. Losses and control cost due to this pest were estimated at about $20 million. This thrips was capable of destroying a cotton crop within a week of its detection. Drought stressed cotton was extremely sensitive to this pest. ACKNOWLEDGMENTS Fiber properties were measured at the Fiber and Biopolymer Research Institute, Texas Tech University, with financial support from Texas Department of Agriculture. Plains Cotton Improvement Program contributed additional financial support to the variety testing effort. The Plains Cotton Improvement Committee is important to the independent variety testing service and to the variety testing strategy of the Texas AgriLife Research breeding program in Lubbock as the High Plains continues to be relied upon as a consistent supplier of high quality cotton. Planting, seed and field preparation, plot maintenance, harvest, sample ginning, and data collection were performed by: Reagan Anders, Joel Arce, Troy Arce, Mark Arnold, Aaron Bost, Natalia Castillo, Trey Cutts, Heather Flippin, Johnny Fuentes, Mitch Juenke, Brad Harris, Carol Kelly, Cherie Lollis, Jimmy Mabry, Nick Macha, Juliana Osorio-Marin, Kim Peters, Alexa Roberts, Monica Sheehan, Raymond Tillis, Dylan Wann, Leslie Wells, and Ruben Zamora. Bacterial blight, Verticillium wilt, and nematode ratings were performed Dr. Terry Wheeler, with the assistance of Garrett Clark and Victor Mendoza. The assistance of all of these people is gratefully acknowledged and appreciated. 5

7 GLOSSARY OF TABLE HEADINGS Yield and Turnout Yield - Pounds of lint harvested per acre. Gin Turnout Lint - Percentage of lint of the stripper-harvested cotton. Seed - Percentage of seed of the stripper-harvested cotton. Agronomic Properties - Determined from hand-snapped samples. Percent Lint Picked - Lint fraction of seed cotton. Pulled - Lint fraction of burr cotton. Boll Size - Weight, in grams, of seed cotton per boll. Seed Index - Weight, in grams, of 100 fuzzy seed. Lint Index - Weight, in grams, of lint from 100 seed (calculated). Seed Per Boll - Average number of seed per boll (calculated). Visual Properties Maturity - Visual assessment of openness on a given date. Storm R esistance - Visual r ating f rom 1 (very l oose bol l type, c onsiderable s eed c otton loss) to 9 (very tight boll type, no seed cotton loss). Height Measured average plant height, in inches, of a given variety. Statistical Analysis Mean - The average value for the trait being observed. c.v.,% - Coefficient of variation. A relative measure of variation within a test, defined as the sample standard deviation expressed as a percentage of the sample mean. LSD - Least significant difference. If the difference between two means exceeds this value, the two means are significantly different at the 0.05 probability level. Fiber Properties - Measured by High Volume Instrument (HVI) Micronaire - A r elative m easure o f fiber l inear d ensity ( mass p er unit length) de termined by a ir permeability. 6

8 Length - An instrument measure of fiber length, expressed in hundredths of a inch, which approximates the classer s staple length. Uniformity - A measure of the uniformity of fiber length in a sample, measured as the ratio of mean length to upper half mean length, expressed as a percentage. Strength - The force required to rupture (or break) a fiber sample, expressed in grams per tex. Elongation - The amount that a fiber sample will stretch prior to breakage. This is a measure of the deformation of fiber at rupture expressed as percent change in length based on the original fiber length. Leaf Index- The visual estimate of the amount of cotton plant leaf material that remains in the lint after the ginning process, ranging from 1 to 7. Rd - Degree of reflectance. This measures how light or dark the fiber sample is, expressed as a percentage. Lower Rd values indicate a grayer sample. +b - Yellowness. This measures the degree of color pigmentation. Higher +b values indicate yellower samples. Color Grade - A function of the Rd and +b of the fiber sample. The color grade indicates the quadrant of the Nickerson-Hunter cotton colorimeter diagram in which Rd and +b values intersect. 1/ Fiber quality determinations are made on samples from two reps. If the color grade from these two samples are identical, only one color grade is reported.
