ABSTRACT

Delta and Pine Land Company is releasing two new Paymaster stripper Roundup Ready (RR) varieties for the 2001 season; PM 2156 RR and PM 2379 RR. PM 2156 RR is an early season, determinant variety best suited for the Northern areas of the Texas High Plains or in re-planting scenarios. PM 2379 RR is a mid to full season variety showing wide adaptability in the stripper market. Both varieties were developed through the backcrossing program using their conventional recurrent parents, DP 2156 and DP 2379, respectively. DP 2156 was developed by Dr. Don Keim and released in 1993 for commercial sale. DP 2379 was developed jointly by Dr. Don Keim and Bo Downer, released for commercial sale in 1997. Fiber quality (fiber length, strength, and micronaire) characteristics are very similar to their recurrent parents. Extensive testing over the past two years shows better yield performance for PM 2156 RR and PM 2379 RR than the current commercial RR standards on the Texas High Plains.
