HETEROSIS STUDIES FOR GRAIN YIELD AND ITS RELATED CHARACTERS IN MUNGBEAN (Vigna radiata L. Wilczek)
Journal Title: International Journal of Genetics - Year 2017, Vol 9, Issue 2
Abstract
A study was conducted in mungbean (Vigna radiata L.) at Department of Genetics and Plant Breeding, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar (Gujarat) to assess the extent of heterosis for thirteen characters including grain yield per plant. Eight lines and four testers were crossed in line × tester mating design to develop 32 F1 hybrids. The analysis of variance revealed considerable genetic differences among the genotypes. The parents (except plant height and seed per pod), hybrids(except number of branches per plant and protein content) and parents vs. hybrids comparisons were significant for days to flowering, days to maturity and pods per plant. A perusal of mean values revealed that the parent MH-521 (13.68 g) was superior in respect of grain yield per plant, whereas among the all hybrids, IPM-02-03 × GM-4 (14.55 g) and GM-9926 × K-851 (14.45 g) recorded maximum grain yield per plant. In the present study, extent of heterosis varied from character to character. The highest standard heterosis for grain yield per plant was registered for the hybrid IPM-02-03 × GM-4 (17.34 %) and GM-9926 × K-851 (16.56 %). Low values of heterosis were observed for days to flowering, days to maturity and protein content, while moderate values of heterosis were recorded for the remaining characters.
