A new, early-maturing, conventional picker variety, DP 393, will be available in significant, commercial quantities by Delta and Pine Land Company in the 2005 season. DP 393 was developed from elite germplasm by Robert McGowen in Scott, MS. Plant structure and maturity of DP 393 were very similar to that of SG 105; however, the first fruiting branch was initiated earlier than SG 105. DP 393 had fewer total nodes and initiated the first fruiting branch earlier than DP 491. Yield and crop value for DP 393 was significantly higher than SG 105 and BCG295. DP 393 had higher gin turnout than SG 105, BCG 245, and BCG295. Staple length was significantly longer for DP 393 compared to SG 105, DP 493, and DP 444 BG/RR. DP 393 had significantly stronger fiber than SG 105 and DP 444 BG/RR, and micronaire was not different from SG 105, DP 493, FM958, and BCG295. DP 393 had significantly higher uniformity index than DP 491, DP 493, DP 444 BG/RR, and FM958. Loan values were significantly higher for DP 393 versus SG 105 and DP 444 BG/RR. Data suggest DP 393 has the yield and fiber quality potential to meet the demands of U.S. growers and mills, as well as those of the international mills. Introgression of new and upcoming transgenes has begun for lines with this germplasm background. [ABSTRACT FROM AUTHOR] |
