Genetic divergence, variability, heritability and genetic advance for growth, pod quality and yield characters in dolichos bean (Dolichos lablab L.var. typicus Prain) germplasm
Thirty five genotypes of dolichos bean germplasm lines were evaluated for genetic divergence, variability, heritability and genetic advance at Vegetable Research Station, Agriculture Research Institute, Rajendranagar, Hyderabad during August, 2016 to March, 2017. Thirty five genotypes were grouped into six clusters based on the relative magnitude of D2 values. The highest number of genotypes (15) appeared in cluster II. The maximum inter cluster distance was observed between cluster III and cluster VI (D2=1780.19).The minimum inter cluster distance was observed between cluster II and cluster IV (D2 =333.46). Maximum intra cluster distance was in cluster IV (D2=249.64). Among the characters, the maximum contribution towards divergence was made by pod yield per plant (26.21%). High heritability estimates were observed for 15 characters and medium heritability was observed for primary branches per plant, number of seeds per pod, seed breadth and 100 dry seed weight. High genetic advance along with relatively high heritability percent were observed for vine length, days to first flowering, pod length, pod width, pod weight, number of pods per plant, seed length, seed breadth, 100 fresh seed weight, protein content, fibre content and pod yield per plant. Hence, due weightage should be given to the above traits, while selection is practiced for multilocation trails improvement of varieties.
期刊介绍:
Legume Research An International Journal. The Journal is an official publication of Agricultural Research Communication Centre. It is designed to bring out the original research articles on genetics, breeding, physiology, bacterial avtivity, production, quality, biochemistry and seeds of legumes crops. The objective of the journal is to serve as a forum for scientific community to publish their research findings on legumes ans to provide basis for new research. Journal is being scanned in the important indexing and abstracting services.
