Association mapping for yield and grain quality traits in rice (Oryza sativa L.)
Association analysis was applied to a panel of accessions of Embrapa Rice Core Collection (ERiCC) with 86 SSR and field data from two experiments. A clear subdivision between lowland and upland accessions was apparent, thereby indicating the presence of population structure. Thirty-two accessions with admixed ancestry were identified through structure analysis, these being discarded from associ...
متن کاملCOMBINING ABILITY ANALYSIS IN RICE ( Oryza Sativa L . )
Twenty hybrids were produced using five CMS lines viz., BRRI3A, BRRI9A, IR73328A, BRRI10A and IR78355A and four restorers viz., BRRI12R, BRRI13R, BRRI14R and BRRI15R following line x tester mating design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids at BRRI, Gazipur, Bangladesh from July 2008 to May 2009. Data were recorded from...
متن کاملcombining ability and heterosis in rice (oryza sativa l.) cultivars
quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...
متن کاملEpistasis for three grain yield components in rice (Oryza sativa L.).
The genetic basis for three grain yield components of rice, 1000 kernel weight (KW), grain number per panicle (GN), and grain weight per panicle (GWP), was investigated using restriction fragment length polymorphism markers and F4 progency testing from a cross between rice subspecies japonica (cultivar Lemont from USA) and indica (cv. Tequing from China). Following identification of 19 QTL affe...
متن کاملevaluation of relationship between some traits of iranian rice (oryza sativa. l.) seedlings under saline conditions
in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...
