A large number of short grain aromatic rice suited to the agro-climatic conditions and local preferences are grown in niche areas of different parts of India and their diversity is evolved over centuries as a result of selection by traditional farmers. Systematic characterization of these specialty rices has not been attempted. An effort was made to characterize 126 aromatic short grain rice la...

A total of 25 adzukibean derived SSR markers were used for molecular diversity analysis among 45 ricebean genotypes and a greengram cultivar, CO 7. Cross species amplification was observed all the in ricebean. Number alleles, present study, varied from one to three. In ricebean, allele size ranged 110 250 bp, whereas it bp. PIC values 0.198 0.689. Out markers, 13 found be polymorphic genotypes....

Assessment of genetic diversity and individual relationships in rice (Oryza sativa) germplasm collections seems to be necessary for future rice breeding program. In order to understand genetic relationships of 30 rice genotypes, nine morphological traits, seven physicochemical properties and twelve RAPD primers were used for study of 30 rice genotypes. Among morphological traits, numbe...

Salinity is considered as one of important physical factors influencing rice (Oryza sativa L.) production. Knowledge of salinity effects on rice seedling growth and yieldcomponents would improve management practices in fields andincrease our understanding of salt tolerance mechanisms in rice. This study was designed to assess the role of Saltol QTL in regards to effects of salinity on plant gro...

DNA fingerprinting has become an important tool for diversity assessment and varietal identification in plant breeding programs. Semi- random PCR primers targeting intron-exon splice junctions (ISJ) were used to evaluate the potential of these markers in identification and classification of rice genotypes. A total of 12 ISJ primers were used for screening fourteen Egyptian rice genotypes, inclu...

to evaluate tolerance of rice genotypes (oryza sativa l.) to soil/water salinity and to utilize selected tolerant genotypes in rice breeding program and further agronomy and physilogical studies 56 rice genotypes have been evaluated. of which 40 rice genotypes from international rice research institute (irri) together with 16 selected tolerant rice genotypes have been tested in two separate exp...

Nitrogen (N) use efficiency in rainfed agriculture is generally low because of poor management and unavailability suitable rice genotypes. There a need to select genotypes with high N for these specific environments, which was investigated at the Bangladesh Rice Research Institute, Regional Station, Rajshahi, two successive years. The performance six genotypes, IR7437170-1-1, BR7873-5 * (NIL)-5...
