Deltapine Seed, a separate operating division of Delta and Pine Land Company conducted numerous on-farm field evaluations of its elite varieties with the Bollgard technology throughout the North Delta. Bollgard varieties evaluated included DP 448B (tested as DPX 9729B), DP 32B, NuCOTN 33B, DP 428B, DP 20B, DP 50B and one competitor, BG 4740. DP 448B produced the highest lint yields per acre followed by DP 32B and NuCOTN 33B. Turnout was lower than the three year average on all varieties due primarily to intense heat during late squaring, early bloom and prolonged drought. DP 32B produced the highest strength. Leaf grade average was well below the base of 4. No differences in fiber length or micronaire were observed between any of the Bollgard varieties tested. All Bollgard varieties produced profitable yields in the North Delta trials ranging from a high of 1372 pounds of lint produced by DP 448B to a low of 1076 pounds. DP 32B and NuCOTN 33B produced the second and third highest yields. Fiber analyses indicated staple, micronaire and strength were similar in all varieties. First position retention was excellent in all varieties.
