Appraisal of the performance of peanut genotypes (Arachis hypogaea L.) from the ICRISAT collection in India

Abstract

Peanut (Arachis hypogaea L.) is a worldwide popular oilseed. In Burkina Faso, production fluctuates from year to year. This fluctuation in yield is linked to the biotic factors which constitute the major constraints of peanuts. To this end, many breeding programs have been set up to select disease-resistant varieties to improve yields. It is with this in mind that this work focused a genetic analysis of traits related to leaf spot resistance of groundnuts. This study was to evaluate the performance of groundnut genotypes of Indian origin, through field screening to identify leafs spot resistant genotypes with good performance. The experimental device was in a completely randomized Fisher block with three repetitions. After setting up the trial, severity of the disease, percentage of defoliation and yield components were noted. Data from all observations were analyzed using the XLSTAT Pro.1 static analysis software. Statistical analysis of the obtained results showed a significant difference between the obtained values in the different genotypes evaluated for all of the above parameters except the yield. At the end of this study, nineteen (19) resistant genotypes and twenty-three (23) genotypes moderately resistant to leaf spot were identified. These resistant genotypes constitute an additional list of resistant varieties and can be used as a source of resistance in a varietal improvement program.
