EYAHIA A field experiment was conducted in the experiment field of SAU and Genetics and Plant Breeding laboratory of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of 6 December 2017 to 5 March 2018. The experiment was conducted in Randomized Complete Block Design with three replications. There were great deal of significant variations for many characters among the genotypes. 30 Mungbean genotypes were tested for genetic variability and correlation coefficient and path analysis among 11 yield contributing traits i.e., plant height, pods per plant, pod length, seed per pod, primary and secondary branches, thousand seed weight and grain yield etc. Considering genetic parameter high genotypic co-efficient of variation DEPARTMENT OF GENETICS AND PLANT BREEDING SHER-E-BANGLA AGRICULTURAL UNIVERSITY DHAKA-1207, BANGLADESH 2017-01-01T00:00:00Z http://localhost:8080/handle/123456789/1959 GENETIC DIVERSITY ANALYSIS OF TOMATO (Solanum lycopersicum L.)

AFRIN, FARHANA populations of Brassicanapus were evaluated to study the genetic variability, correlation, path analysis, genetic diversity and selection of population based on yield and yield component traits. The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka during November 2016 to February 2017. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Analysis of variance revealed significant variations were observed among the genotypes for all the traits studied. Considering genetic parameters, high GCV values were observed for number of secondary branches per plant and seed yield per plant. High heritability values coupled with high genetic advances in per cent mean were obtained for number of secondary branches per plant, number of siliqua per plant and seed yield per plant. Correlation studies revealed significant positive association of seed yield per plant with plant height, number of secondary branches per plant, siliquae per plant and 1000 seed weight at both genotypic and phenotypic levels. Path coefficient indicated positive direct contribution towards seed yield per plant through siliquae per plant, seeds per siliqua, 1000 seed weight, plant height and primary branches per plant.The genotypes were grouped into five clusters. The highest nine populations were included under the Cluster III and the cluster II contained the lowest with solitary. Cluster II and cluster V shown the highest distance indicating genotypes from these two clusters were diverse. While the lowest inter-cluster distance was observed between cluster III and IV. Considering group distance, seed yield per plant and other agronomic performance genotypes G6 (Nap108 X Nap2066 (Nap2066)), G8 (Nap108 X Nap9908( Nap9908)), G10 ( Nap205 X Nap0130 ( Nap0130)), G11 ( Nap206 X Nap205 (Nap205)), G14 (Nap2066 X Nap0130 (Nap2066)), G20 ( Nap9905 X Nap9908 ( Nap9905)) and G29 ( Nap9906 X Nap0130 ( Nap9906)) might be used as open pollinated verities and need to further performance and stability test; and could be used as parents in future hybridization program.
