ABSTRACT

DP 449 BG/RR is a new mid-season cotton variety being released by Delta and Pine Land Company for the 2003-growing season. DP 449 BG/RR is a smooth-leaf, medium height variety developed at D&PL's Maricopa, AZ research location and has been tested widely in the 2001 and 2002 growing seasons. The highlights of DP 449 BG/RR's performance are improved fiber quality, excellent yield stability, and improved yield potential and crop value per acre over standard DP&L and com-petitor varieties. Fiber micronaire is reduced and fiber strength is improved when compared to DP 451 B/RR, DP 458 B/RR, DP 555 BG/RR, and ST4892BR. Supplies of DP 449 BG/RR for the 2003 growing season are projected to be good introduc-tory quantities.
