Abstract

Vigna radiata is a crucial pulse growing most of the parts of the globe. Imbibition is a first and key physiological process mainly depends on the permeability of seed coat. Looser seed coat invites the imbibition process quickly rather than harder seed coat. Based on this the present experiment was conducted to study the evaluation of mungbean genotypes for morpho - physiological traits imparting tolerance for preharvest sprouting. The experiment was laid out in Randomized block design, with sixteen genotypes i.e., AKM-8802, PKV-GREEN GOLD, PKV-AKM-4, BM-2002-1, BM-2003-2, KOPERGAON, AKM-9907, AKM-09-2, AKM-10-16, AKM-10-21, AKM-0603, AKM-10-05, AKM-10-13, AKM-10-24, AKM-8803 and AKM-9801with three replications. The result revealed that high hard seed percentage, lower germination in pod and seed, less seed and pod moisture percentage observed in AKM-9801, AKM-9907, BM-2002-1 and AKM-10-05, genotypes. This study delves into the strategies and key traits that confer preharvest sprouting tolerance in Vigna radiata.

Conclusion

The genotypes AKM-9801 (61.33%), AKM-9907 (59.67%), and BM-2002-1 (53.33%) exhibited a higher percentage of hard seeds, while lower seed germination within the pod was observed in genotypes AKM-9907 (58.56%) and AKM-9801 (61.30%). Additionally, these two genotypes, AKM-9907 (42.33%) and AKM-9801 (44.96%), displayed lower overall seed germination percentages. Furthermore, genotype AKM-9801 (12.40%) and BM-2002-1 (13.10%) demonstrated reduced moisture content in their seeds. Based on the combination of high hard seed percentages, pod pubescence, lower germination rates within the pod and for individual seeds, as well as reduced seed and pod moisture percentages, it can be concluded that the genotypes AKM-9801, AKM-9907, BM-2002-1, and AKM-10-05 exhibit greater tolerance to preharvest sprouting.
