Identification of morphological indices of physiological maturity in soybean (Glycine max) genotypes
Year: 1995
Type: article
Abstract: An experiment was conducted during rainy season of 1992 and 1993 to identify the morphological indices of seed maturation and physiological maturity in 10 genotypes ('Punjab 1', 'Ankur'., 'JS 75-46', 'JS 78-80'. 'JS 79-81', 'JS 81-303', 'JS 81-607', 'JS 81- 335', 'JS 81-1625' and 'PK 472') of soybean [Glycine max (L.) Merr.]. All the genotypes reached the physiological maturity by 56 days after anthesis accompanied with higher dry weight of seed (83.05%), dry weight of plant (18.73 g/plant), seed index (10.39 g), germinability (88.4%) and seedling vigour (7.06 cm seedling length and 0.081 g dry weight). In all the genotypes seed and pod volumes (0.021 ml and 0.10 ml) were maximum at 49 days after anthesis. At physiological malurity 4-10.66 leaves/plant were retained hy the genotypes and colour of the pod and stem became dark red·brown to brown. The seeds collected at 35 days after anthesis did not germinate.
