Abstract
Twenty eight F1 crosses along with eight parents were studied to get information on the extent of heterosis over mid parent, better parent and standard parent for morphological, yield and yield attributes. The maximum relative herterosis for pod yield per plant 101.52%, better parent heterosis 92.73% and standard heterosis 108.54 respectively. The crosses viz., TIR-25 x ICGV-99029 for kernel yield per plant, ICGV-91114 x TCGS-647 for pod yield per plant, Tirupati-4 x JL-220 for number of well filled and mature pods per plant, JL-220 x ICGV-99029 for 100 kernel weight, K-1375 x TCGS-647 for sound mature kernel per cent and TPT-4 x K-1375 for shelling per cent were the best heterotic crosses over the better parent. These hybrids were identified as promising for many desirable traits and they may be useful in exploiting hybrid vigour in groundnut.
