Progress in 2010 - Groundnuts

Compilation of a database of phenotypic data of drought assessments from six locations (India, Niger, Mali, Senegal, Tanzania and Malawi) spanning six years, and statistical analysis of the same, was completed. Disease resistance was confirmed for some entries from Year 3 trials of Phase I. The reference collection was analysed for fodder quality traits in India, showing large variation in the germplasm. Analysis of lysimetric data generated in the past two-and-a-half years is almost complete. These data will enhance understanding of traits that are important for groundnut adaptation to intermittent drought. Excellent proof of concept has been obtained that higher disease resistance can be achieved by introgressing segments of the wild progenitors. Five F2:3 populations involving a stable source of early leaf spot (ELS) resistance were advanced to the next generation to produce F4 seed. These will be multiplied to produce F5 seed for phenotyping in the 2011 cropping season (June–September).
