Correlation Studies in Rice (Oryza sativa L.)
Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
متن کاملGenetic Diversity of Drought Tolerant Upland Rice (Oryza sativa L.) Genotypes
Genetic divergence of thirty three drought tolerant rice (Oryza sativa L.) genotypes were studied through Mohalanobis’s D and principal component analysis for twelve characters. The genotypes were grouped into seven clusters. The cluster I and II were comprised of the maximum number of genotypes (eight) in each followed by cluster V containing five genotypes. The highest inter-cluster distance ...
متن کاملGenetic Diversity in Sadajira Rice (Oryza sativa L.) Germplasm
Genetic diversity of 40 traditional Bangladeshi rice genotypes was studied under rainfed condition through Mahalanobis D statistic for grain yield and yield contributing characters. The genotypes were grouped into six clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intra-cluster dist...
متن کاملGenetic polymorphism in rice (Oryza sativa L.) through RAPD analysis
Random Amplified Polymorphic DNA (RAPD) assay was performed to estimate genetic polymorphism in six different rice (Oryza sativa L.) cultivars viz. Basmati 370, DM 25, IRATOM 24, Binadhan 6, TNDB 100 and Y 1281. Three out of the 15 decamer random primers showed amplification of genomic DNA in 24 individuals. The primers produced a total of 26 bands of which 14 were polymorphic. Proportion of po...
متن کاملGENETIC DIVERSITY ANALYSIS IN RICE (Oryza sativa L
The experiment was conducted under the agro-ecological zone of Modhupur Tract (AEZ-28) to determine the genetic diversity among 39 rice genotypes, collected from Bangladesh Rice Research Institute, Lal Teer Seed Ltd. and Chittagong Hill Tracts. The genotypes were grouped into six clusters based on Mahalanobis’s D 2 statistics and Canonical Variate Analysis. Cluster I consisted with the highest ...
