Identification of major and minor genes associated with heading date in an indica × indica cross of rice (Oryza Sativa L.)
In this study, quantitative trait loci (QTLs) controlling rice heading date were detected in a F2:3 population derived from a cross between an indica rice variety, Tarom Mahalli, with early heading date, and an indica variety, Khazar, with late heading date. SSR linkage map was constructed using 74 polymorphic markers and 192 F2 individuals and covered a total of 1231.50 cM of rice genome. QTL ...
متن کاملInfluence 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 ...
متن کاملEvaluation of genetic parameters and heritability of traits in rice (Oryza sativa L.) using diallel method
To study the genetic control of grain yield and its components in rice using Hayman graphical method, 56 progenies obtained from diallel mating with eight parents (64 genotypes in total) were evaluated using randomized complete block design with three replications at research field of the Rice Research Institute of Iran in 2013. Agronomic traits, grain yield and its components were measured and...
متن کاملExpression patterns of photoperiod and temperature regulated heading date genes in Oryza sativa
In plants, flowering is a major biological phenomenon, which is regulated by an array of interactions occurring between biotic and abiotic factors. In our study, we have compared the expression profiles of flowering genes involved in the flowering pathway, which are influenced by conditions like photoperiod and temperature from seedling to heading developmental stages in two Oryza sativa indica...
متن کاملHierarchical additive effects on heterosis in rice (Oryza sativa L.)
Exploitation of heterosis in crops has contributed greatly to improvement in global food and energy production. In spite of the pervasive importance of heterosis, a complete understanding of its mechanisms has remained elusive. In this study, a small test-crossed rice population was constructed to investigate the formation mechanism of heterosis for 13 traits. The results of the relative mid-pa...
