Description |
The present investigation entitled “Morpho-physiological characterization of Soybean cultivars for efficient photo assimilate partitioning and yield” was carried out during kharif season 2015 at Research cum instructional farm IGKV Raipur (C.G.) in the Department of Plant Physiology. The experiment was conducted to explicit out the morpho-physiological markers and plant architecture, growth pattern for efficient partitioning of photo assimilates and high sink realization and yield via evaluating 44 cultivars of three groups i.e. early medium and long in randomized block design replicated thrice. The morpho-physiological growth and yield parameters were taken at various growth phase and time i.e. 40, 60, 90 days after sowing (DAS) and at physiological and physical maturity. The first flower initiating node was also calculated. The correlation studies indicated that the HI was highly positively correlated with test weight, seed yield and plant height. Seed yield was also positively correlated with test weight, no. of pods plant-1, no. of seed plant-1. However BY (biological yield) was highly negatively correlated with physiological maturity, chlorophyll SPAD value. The no. of seeds pod-1 was highly negatively associated with days to flower initiation. No. of seed plant-1, was positively correlated with no. of leaves plant-1, no. of branches plant-1 and no. of pod plant-1. It was observed that the cultivars KDS 775 (E), RSC 10-30 (E), NRC 123 (M) and PS 1570 (L) have significant higher HI amongst their groups. KDS 775 have high test weight and low biological yield. The cultivars RVS 2010-1 (E), KDS 975 (E), RHC 10-04 (M), NRC 117 (M), JS 20-94 (M) and JS 95-52 (C) (L) and RSC 10-29 (L) have significantly higher seed yield amongst their groups of various duration i.e. ‘E’ early, ‘M’ medium, and ‘L’ long. These cultivars have less number of flower drop, more sink realization and efficient photo assimilates partitioning towards economic sink. These cultivars have significantly higher number of branches RHC 10-04 (M) JS 97-52 (c) (L), higher leaf area RHC 10-04 (M) RSV 2010-1 (E) and DSb 29 (L). These cultivars also having higher no. of pods plant-1 and cultivar JS 20-94 (M) have minimum no. of pod bearing node. Cultivars VLB 202 (E), TS 72 (M), MACS 1480 (L) have significantly higher CGR. However, RVS 2010-1 (E), RHC 10-04 (M) and DSb 29 (L) have higher LAI. The average maximum NAR, RGR were observed in VLB 202 (E), TS 72 (M) and SL 1074 (L) cultivars of various groups. |
