Abstract

Hybridization is challenging in pea crop due its flower structure. Present study was carried out with 51 genotypes (36 hybrids developed by crossing 12 lines and 3 testers) of garden pea (Pisum sativum L). The per cent heterosis over mid-parent and better parent was worked out for yield and yield related attributes. Heterosis was valued in this study. Heterosis values were significant over better parent and mid parent in desirable direction in most crosses for yield and quality characters under studies. The crosses involving Palam Priya × Azad Pea-1 and Palam Priya × VL-Ageti Matar-7 exhibited maximum magnitude of positive and significant heterosis over mid-parent and better parent for fruit yield per plant and fruit yield per hectare in garden pea indicating the potential of selected hybrids over existing homozygous parental lines and exploitation of dispersion of alleles between the parents and mean directional dominance gene action in crop improvement. The F2 population can be uti

Conclusion

On the basis of present studies, it can be concluded that the hybrids namely Palam Priya × Azad Pea-1 and Palam Priya × VL-Ageti Matar-7 were found to be superior hybrids selected for yield since these crosses exhibited significant heterosis and sca effects for yield per hectare. These crosses can be further assessed for their yield stability to confirm their potentiality and also their adaptability to agro-climatic conditions of Jammu region before exploiting them on commercial scale. The segregating material from further generation can be utilized for isolating potential material.
