Research on combining early maturity and multiple disease resistance was carried out by testing 50 advanced breeding lines in two replicated runner trials at two locations in West Texas and one location in South Texas. Over one half of the early-maturing breeding lines had yields equal to the released cultivars with 10 lines having numerically higher yields. Most promising was the fact that two of these lines yielded over 1,000 lbs/a better than Tamrun OL12 indicating improvement upon the yield of our next generation, early maturing breeding lines. Additionally, we tested another 57 early generation breeding lines developed from crosses between our best early maturing lines and Tamrun OLl 1 which has resistance to Sclerotinia blight and excellent grade characteristics. These lines went through two years of selection under heavy Sclerotinia blight pressure at Stephenville and this was the first year of yield testing on these materials. They were only tested at one location in West Texas due to limited seed availability. Several of the breeding lines yielded numerically higher than the either of the parents and one of the highest yielding lines tested about 85% mature compared to 54% for Tamrun OLl 1.
