Evaluation of Genetic Diversity in Agromorphological Traits of Forty Two Aman Rice Genotypes (Oryza sativa L.) Using D2 Analysis
Journal Title: Journal of Experimental Agriculture International - Year 2015, Vol 8, Issue 5
Abstract
The experiment was conducted with forty two genotypes of rice at the experimental farm of Sher-e-Bangla Agricultural University, Dhaka during the period of July 2013- December 2013 to estimate the diversity among 42 Aman rice genotypes. Based on D2 analysis the genotypes were grouped into five different clusters. Clusters IV had the maximum fourteen and cluster III had the minimum three genotypes. The highest inter-cluster distance was observed between II and III and the lowest was between IV and V. The highest and lowest intra-cluster distance was observed in III and IV respectively. Genotypes included in cluster V were important for total tillers per plant, effective tillers per plant, days to 50% flowering and thousand grains weight; cluster III were important for filled grains per panicle and unfilled grains per panicle; cluster IV were for plant height and yield per plant. Considering the diversity pattern and other agronomic performances, the genotypes Special from AL-29, AL-36, PP-4B(i), AL-17(iii)B, AL-17(iii), AL-17(ii)A, Special from-129, Special from 17(iv), AL-44(i), AL-17, Special from AL-36(D), PP-48, IR-25B, Special from AL-33, IR-25B (Tall), P-5B might be considered better parents for the future efficient hybridization programme.
