Abstract

The utility of heterosis per se may not be of much use, but cross combinations showing excellent hybrid vigour can be used in developing high yielding forage hybrids in maize crop. The present investigation was conducted at B.A. College of Agriculture, Anand Agricultural University, Anand. The experimental material consisted of 50 F1 and their10 parents (5 females and 10 males). Material was sown in randomized complete block design with three replications. The hybrids were evaluated to know the extent of heterosis over better parent. The maximum heterobeltiosis for the most important character green forage yield per plant observed in the hybrid IC 130882 × GDRFG 1644 (36.98). This hybrid can be identified as potential hybrid for wide spread cultivation and commercial exploitation after necessary testing. This cross can also be advanced for isolation of superior genotypes and selected genotypes may intermated to map up fixable genetic variance

Conclusion

It was concluded that the cross combinations viz., IC 130882 × GDRFG 1644 depicted significantly the highest heterobeltiosis and considered as good cross combination for green forage yield. This hybrid can be identified as potential hybrids for wide spread cultivation and commercial exploitation after necessary testing. This cross can also be advanced for isolation of superior genotypes and selected genotypes may intermated to map up fixable genetic variance
