Narrative
From 2012 to 2016 the two candidate germplasm yielded higher than the check cultivars. USDA MD 16-1 yielded 14 % higher than MD 10-5, the most recent release from the program and 8 % higher than MD 25, a high yielding, quality germplasm in the Mississippi Delta. USDA MD 16-2, on the other hand, gave higher yields than all the check varieties but its' yield was 6 % lower than USDA MD 16-1. In the 2015 and 2016 RBTN (Regional Breeder Testing Network) tests at 13 locations across the Southeast,which included 34-36 breeding lines and checks USDA MD 16-1 had the highest yield (1701 kg/ha) The check varieties in the RBTN (SG 747, DP 393, DP 493, MD 15, and FM 958) all had significantly lower yield than MD 16-1. In addition to its good yield performance, USDA MD 16-2 had good fiber length (31-34 mm) and the strongest fiber in the RBTN tests (36.2 g/tex) MD 16-1 had fiber length of 29-31 mm. Both USDA MD 16-1 an USDA MD 16-2 had longer, stronger and more uniform fibers than MD 10-5 and the other check varieties. The negative associations between lint yield and fiber quality have been a persistent problem for cotton breeders for a long time. These negative associations have been significantly reduced in some germplasm populations developed by public cotton breeding programs. In a recent report, however, analysis of 102 strains and commercial cultivars evaluated across 56 environments in the Regional High Quality Tests from 2001 to 2007, the genetic correlations between lint yield and fiber strength between lint yield and fiber length were -0.63 and -0.56, respectively. The data from 2012 to 2015 for USDA MD 16-1 and USDA MD 16-2 indicated that the correlations between lint yield and fiber quality were -0.16 for fiber strength and -0.14 for fiber length. These significant reductions are steps in the right direction.

Pedigree
Description:
Two crosses, MD 25-51 X MD 10-9-1 and MD 25-51 X MD 10-9-10 were made at the Jamie Whitten Delta State Research Center, USDA-ARS, Stoneville in 2010. The F1 was grown in the winter nursery in Mexico in 2010. The F2 was planted at Stoneville, MS in 2011. One boll per plant was bulked to go to F3 in 2012. This process was repeated during 2013 (F4). In 2014 (F5) individual plants USDA MD 16-1 and USDA MD 16-2 were selected to be tested in replicated trials for yield and quality in 2015 and 2016.
