Detection and characterization of epistasis between QTLs on plant height in rice using single segment substitution lines
Hua-jing-xian 74 and its 12 single segment substitution lines (SSSLs) in rice were used as crossing parents to construct a half diallel crossing population. A total number of 91 materials were grown under three planting densities. By analysis of average plant height (PH) over all environments 10 SSSLs were detected with significant additives and 6 SSSLs with significant dominances. These SSSLs ...
متن کاملthe stady and analysis of rice agroclimatology in lenjan
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولIdentify QTLs for grain size and weight in common wild rice using chromosome segment substitution lines across six environments
Grain size and weight are important determinants of rice yield. The identification of beneficial genes from wild rice that have been lost or weakened in cultivated rice has become increasingly important for modern breeding strategies. In this study, we constructed a set of chromosome segment substitution lines (CSSLs) of wild rice, Oryza rufipogon with the indica cultivar 9311 genetic backgroun...
متن کاملDetection of QTLs to reduce cadmium content in rice grains using LAC23/Koshihikari chromosome segment substitution lines
To advance the identification of quantitative trait loci (QTLs) to reduce Cd content in rice (Oryza sativa L.) grains and breed low-Cd cultivars, we developed a novel population consisting of 46 chromosome segment substitution lines (CSSLs) in which donor segments of LAC23, a cultivar reported to have a low grain Cd content, were substituted into the Koshihikari genetic background. The parental...
متن کاملExploitation of heterosis loci for yield and yield components in rice using chromosome segment substitution lines
We constructed 128 chromosome segment substitution lines (CSSLs), derived from a cross between indica rice (Oryza sativa L.) 9311 and japonica rice Nipponbare, to investigate the genetic mechanism of heterosis. Three photo-thermo-sensitive-genic male sterile lines (Guangzhan63-4s, 036s, and Lian99s) were selected to cross with each CSSL to produce testcross populations (TCs). Field experiments ...
