Callus Induction in Rice, Oryza sativa L.

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...

Increased Regeneration Efficiency in Seed Derived Callus of Rice (Oryza sativa L.)

In five cultivated rice varieties e.g., Nonabokra, PNR 381, Taipei 309, Koshika and TKM 11 the response in the initiation of callus and its size varied greatly among varieties, salt concentrations (NaCl and Na2SO4) and their interaction. Better regeneration ability of Nonabokra, Koshika and TKM 11 was found to be correlated to small size callus with a high concentration of Na2SO4. The regenerat...

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

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...
