Abstract:

Fifteen pigeonpea genotypes were studied to establish the role of seed-Fe content in maintaining seed longevity of pigeonpea genotypes and the results revealed the clear genotypic variability with respect to storability among different pigeonpea genotypes. The genotype with highest seed-Fe content (85.01 ppm) proved as good storer by recording highest seed quality parameters viz., seed germination (84.57 %), seedling length (27.67 cm), seedling vigour index (1303), seedling dry weight (80.67 mg g), speed of germination (23.29 %), dehydrogenase enzyme activity (0.551 OD value), α-amylase activity (28.46 mm) with lowest electrical conductivity (1.04 µS/cm) and moisture content (7.29 %) at the end of twelve months of storage period. Whereas, genotypes with low seed-Fe content exhibited lowest seed quality parameters.
