tailieunhanh - Study of genetic variability for different traits in soybean

An experiment was conducted to study genetic variability present in the thirty six genotypes and observations were recorded on various yield and yield contributing characters viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, 100 seed weight and grain yield per plant. Analysis of variance revealed highly significant differences among the genotypes for the all the characters. | 2019 8 12 2991-2994 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 12 2019 Journal homepage http Original Research Article https Study of Genetic variability for different traits in Soybean Sidramappa C.

Analysis of variance revealed highly significant differences among the genotypes for the all the characters. High PCV and GCV were observed for branches per plant pods per plant and yield per plant indicate the presence of wider adaptability for these traits in the genotypes studied suggested the less influence of environment in the expression of characters. High heritability coupled with high genetic advance as percent of mean was observed for days to 50 flowering plant height branches per plant pods per plant 100 seed weight and seed yield per plant indicating operation of additive gene action and the ample scope for improvement in these traits through simple selection. Introduction Soybean Glycine max L. Merrill is a major oil seed crop in the world and is called as a golden bean or miracle bean because of its nutritional qualities having 20 oil and 40 percent protein which has biological value as meat and fish protein and rich in amino acids like lysine and tryptophan. Genetic variability is the basic requirement for crop improvement as this provides .
