Abstract

                                In the storage study, COPH 2 pigeonpea hybrid and its parental seeds dried to 8 per cent moisture, treated with chlorine based halogen mixture (calcium oxychloride:calcium carbonates:arappu leaf powder (Albizia amara) @ 5:4:1 ratio) @3 g kg of seeds and packed in high density polyvinyl bag maintained higher germination and seedling vigour during storage than control and carbaryl + bavistin treatments. Seeds of female parent could be stored safely upto 15, male parent for 24 and hybrid for 21 months, which indicated that male parent is a good storer, female parent is a poor storer and the hybrid behaved intermediary between male and female parents.

Key words : COPH 2 pigeonpea hybrid and its parents, Seed treatments, Storage containers, Vigour and viability.
