Develop and identity peanut lines adapted to important ecological areas of Sahelian West Africa and Texas that are resistant to pathogens causing economic loss and effectively utilize available water, and to identify cultural practices that will maximize the yield potnetial of cultivars in these environments.


1.In Burkina Faso, TxAG-3 and several germplasm lines from South America had leafspot scores as low as the local rheck RMP 12 and significantly lower than U.S. cultivars. 2. Several South American germplasm lines and two selections from a TxAG-3 x Tarmnut-74 cross had significantly lower rust scores than local and U.S. checks at Niangoloko, Burkina F,.o. 3. Reaction to early and late leafspot of selections from the sixth backcross of diploid species to Florunner and Tamnut-74 approached that of nonrecurrent parents. 4. Yields of advanced U.S. breeding lines were not significantly different from those of local checks in Bambey or Nioro, Senegal under non-irrigated conditions. Under irrigation in Texas, Senegalese cultivar Sn57-422 yielded as well as cultithe best U.S. cultivar at both Yoakum and Bryan. It also yielded as well as U.S. entries under rain-fed conditions at Waller, Taxas. 5. Evaluation of U.S. and ICRISPAT germplasm for reaction to Tomato Spotted Wilt Virus under natural infection resulted in infection at last rating date varying from 14% to 51% in one the test, and from 28% 84% in a second test.
