COMBINING 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 کاملGene Action, Combining Ability, Genetic Expression of Heterosis and Characterization of Rice (Oryza sativa L.) Genotypes for Quality Traits
Present investigation was conducted to estimate the per se performance, combining ability and heterosis for grain quality traits in rice using line × tester mating design. Analysis of variance with respect to crosses revealed significant differences for all the traits studied. GCA and SCA results revealed the predominance of SCA variance in relation to GCA variance for all the traits. For aroma...
متن کاملCombining Ability and Gene Action in Sunflower Using Line*Tester Method
In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...
متن کاملAssociation 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 کاملGenetic variation and association analysis of some important traits related to grain in rice (Oryza sativa L.) germplasm
The identification of genomic loci involved in control of quantitative traits receives growing attention in plant molecular breeding. The present study was carried out to evaluate the genetic variability among 48 rice genotypes and determine the genomic regions associated with ten grain related important traits. A total number of 63 alleles were detected by 18 selected SSR markers from differen...
