What is Evaluation and Selection of Interspecific Lines of Groundnut ( Arachis hypogaea L.) for Resistance to Leaf Spot Disease and for Yield Improvement about?
Early and late leaf spot are two devastating diseases of peanut (__Arachis hypogaea__ L.) worldwide. The development of a fertile, cross-compatible synthetic amphidiploid, TxAG-6 ([__A. batizocoi__ × (__A. cardenasii__ × __A. diogoi__)]^4x^), opened novel opportunities for the introgression of wild alleles for disease and pest resistance into commercial cultivars. Twenty-seven interspecific lines selected from prior evaluation of an advanced backcross population were evaluated for resistance to early and late leaf spot, and for yield in two locations in Ghana in 2006 and 2007. Several interspecific lines had early leaf spot scores significantly lower than the susceptible parent, indicating that resistance to leaf spot had been successfully introgressed and retained after three cycles of backcrossing. Time to appearance of early leaf spot symptoms was less in the introgression lines than in susceptible check cultivars, but the opposite was true for late leaf spot. Selected lines from families 43-08, 43-09, 50-04, and 60-02 had significantly reduced leaf spot scores, while lines from families 43-09, 44-10, and 63-06 had high pod yields. One line combined both resistance to leaf spot
