Abstract

 

A set of 28 crosses involving 8 parents were studied to get the information on the extent of heterosis over mid parent, better parent and standard parent for yield and physiological attributes. The maximum better parent heterosis for pod yield was observed to be 92.73% and that of mid parent and standard parent was found to be 101.52 and 108.54% respectively. TIR-25 x TCGS-647, TPT-4 x TIR-25, K-1375 x TCGS-647, ICGV-91114 x TCGS-647, TIR-25 x TCGS-647 and TIR-25 x ICGV-99029 hybrids were identified as promising for many desirable physiological traits and they may be useful in exploiting hybrid vigour in groundnut.

 

Key words: Heterosis, water use efficiency, yield, groundnut.
