Rice (Oryza sativa L.) is an important global food commodity crop. Its yield was affected by genotype, environment, and the interaction between genotype environment that demands development of diverse tolerant rice to increase yields adaptation. Genotype Environment for Tongil types with doubled haploid (DH) were evaluated in three locations. A randomized complete block design replicated times ...

Zn deficiency is one of the most important micro-nutritional disorders in lowland rice. In this work, fourteen Iranian rice cultivars were studied in the field as well as in solution culture experiments to determine genotypic differences for traits characterizing Zn efficiency. A low uptake efficiency was observed in some (Onda and Kadoos) of the Zn-inefficient genotypes. A relatively high corr...

The molecular marker is a useful tool for assessing genetic variations and resolving cultivar identities. Information on genetic diversity and relationships among rice landraces from Bangladesh is currently very limited. Thirty-five rice genotypes including 33 landraces and 01 HYV of Bangladesh and 1 Indian landrace of particular interest to breeding programs were evaluated by means of random a...

Rice cold tolerance at the germination stage is important in Rio Grande do Sul (RS) where temperatures below 15°C prevent or reduce germination and plant establishment in early sowings. The present study aimed at identifying an adequate method for cold tolerance evaluation of the rice germination stage and at verifying the variability among 24 rice genotypes of different origins. Cold tolerance...

Genetic based knowledge of different vegetative and yield traits play a major role in varietal improvement of rice. Genetic variation gives room for recombinants which are essential for the development of a new variety in any crop. Based on this background, this work was carried out to evaluate genetic diversity of derived mutant lines and establish relationships between their yield and yield c...

BACKGROUND Salinity is a major environmental factor limiting productivity of crop plants including rice in which wide range of natural variability exists. Although recent evidences implicate epigenetic mechanisms for modulating the gene expression in plants under environmental stresses, epigenetic changes and their functional consequences under salinity stress in rice are underexplored. DNA met...
