Identification of new sources of early-maturity in groundnut core collection

Early-maturing high-yielding groundnut (Arachis hypogaea L.) cultivars are needed for shot growing season, multiple cropping, and to avoid late season droughts. In almost all breeding programs only a few sources of early-maturity (Chico, Gangapuri, JL 24; mainly Chico) have been used. The aim of our research was to identify new sources of early-maturity through evaluation of core collection developed at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, India
