Groundnut is an important oilseed crop grown throughout the year. Groundnut having three types of growth habit, Spanish and Valencia habit types does not have fresh seed dormancy, while Virginia types having longer seed dormancy. Lack of seed dormancy in the Spanish bunch and Valencia varieties have a major problem of in-situ germination resulting from unpredictable rainfall at crop maturity while prolonged seed dormancy in Virginia types prevents farmers to use own seed immediately after harvest for sowing purpose and also having longer duration than Spanish bunch cultivars. Therefore, Spanish bunch cultivars are most suitable because of fit well in the kharif, rabi and summer seasons with at least three week fresh seed dormancy to avoid pod losses due to unpredictable rainfall at the time harvesting.
