Abstract:

The present experiment was conducted to study correlation for yield and yield contributing characters in BC1F1 generation derived from three crosses of groundnut viz., CO 7 × GPBD 4, TMV 2 × GPBD 4 and TMV (Gn) 13 × GPBD 4. Correlation analysis indicated that kernel yield per plant was significant and positively associated with number of pods per plant, hundred pod weight, hundred kernel weight, shell weight, shelling out-turn and pod yield per plant for all the three crosses. Hence, all these characters may be considered as selection indices for kernel yield improvement in groundnut. Among LLS and rust disease score, LLS alone had significantly negative and positive association with shelling out-turn and sound mature kernel per cent, respectively. However, both disease score has no association with kernel yield and other yield components. Hence, development of high kernel yielding plants with resistance to both foliar diseases is possible.
