Abstract

Nine crosses involving non-dormant erect bunch cultivars of groundnut as ovule and dormant inter-specific Virginia bunch derivatives as pollen parents were assessed for seed dormancy at F4 generation. Significant amount of heritable variation in thecrosses revealed scope for slection. Considerable proportion of segregants were obtained for dormancy (26%), erectness (39%) and high yield potential (71%). The proportion of dormant plants with erect habit (9.4%) and those with high yield potential (1.4%) were very low. However, the proportion of dormant or high yielding types among erect segregants was comparable to that of the whole population indicating indepen dent nature of habit with dormancy and productivity. Recovery of desirable segregants could be enhanced by raising large segregating population or by intermating of the selected segregants
