Increasing Crop Diversity and Productivity of Rice (Oryza Sativa L.)-Wheat (Triticumaestivum L.) Cropping System through Bed Planting

DIVERSITY ANALYSIS IN BORO RICE ( Oryza sativa L . ) ACCESSIONS

An experiment was conducted with 36 accessions of traditional (local) Boro rice germplasm accessions of three different groups (20 accessions as Kaliboro, 12 as Jagliboro and 4 as Tepiboro) during Boro season 2004 at BRRI farm to identify the duplicates with the help of morph-agronomic characters. On the basis of D values, the 36 genotypes were grouped into six clusters with a range of intra (0...

Genetic 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...

GENETIC 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 ...

Genetic 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...
