Upgradation of French bean (Phaseolus vulgaris L.) seed production through priming

Abstract

To obtain the quantity and quality of French bean seed, the seed priming procedure was functional using organic and inorganic compounds in three modes of priming viz. hydro-priming, osmo-priming (PEG6000, CaCl2, KNO3) and halo-priming (Thiourea, GA3) with control under 6 hours treatment durations. In assessment, the observations allied to eight plant growth and yield attributes including yield for getting the real exposure of qualitative and quantitative parameters. The treatments, T2 (Thiourea, 750 ppm) was most functioning with significant variation among diverse treatments except in seeds pod-1. In genotypes, V1 showed high significant demarcation predominantly in yield attributes and yield though, V2 was hopeful for a few characters predominantly in days to flower with number of pods and seeds. The treatments interaction with genotypes showed non-significant demarcation only in seeds pod-1 but, interacted value T2V1 was highest considering all parameters. The parameters related to seed weight were pronounced contributor in qualitative and quantitative upgradation in seed where the number of seeds or pods were immaterial. Diverse treatments specified the extent of effects on seed or plant to upgrade the quality. Therefore, the treatment T2 may be considered for French bean seed production to obtain capable seed for upcoming generation.
