Genotype-Environment Interaction in Irrigated Rice (Oryza sativa L.)

Analysis of Genetic and Genotype × Environment Interaction Effects for Agronomic Traits of Rice (oryza Sativa L.) in Salt Tolerance

A diallel cross experiment of 4 rice (Oryza sativa L.) female and 6 male varieties was conducted to study the genetic effects and their interaction with salt-stress condition of 7 agronomic traits in normal and salt-stressed planting conditions. The panicle length (PL), effective number of panicles per plant (ENP), plumped number of grains per panicles (PNG), total number of grains per panicles...

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...

Influence of epistasis and QTL x environment interaction on heading date of rice (Oryza sativa L.).

QTLs for heading date of rice (Oryza sativa L.) with additive, epistatic, and QTL x environment (QE) interaction effects were studied using a mixed-model-based composite interval mapping (MCIM) method and a double haploid (DH) population derived from IR64/Azucena in two crop seasons. Fourteen QTLs conferring heading date in rice, which were distributed on ten chromosomes except for chromosomes ...

Assessment of genotype × environment interaction and grain yield stability of selected aerobic rice (Oryza sativa L.) genotypes in northern region of Iran

 For sustainable rice production in Iran the optimum use of production resources and the reduction of production costs are the two important issues. In this situation, water availability is a major limiting factor in sustainable rice production. Hence, changing of rice production system from lowland irrigated to aerobic production system, which is based on dry-seed sowing in non-puddled and non...
