Identification of main and epistatic QTLs for grain yield related traits in a recombinant inbred lines population of rice (Oryza sativa L.)
Rice yield as a complex trait is the main target in most rice breeding programs. To map the main and epistatic QTLs controlling grain yield and yield components, an experiment was carried out using a 129 F6 recombinant inbred lines population (IRA population) originated from a cross between Alikazemi / IR67017-180-2-1-2, in 2015 growing season in two locations, Rasht and Tonekabon, Iran. The e...
متن کاملGenetic diversity analysis of recombinant inbred lines of rice (Oryza sativa L.) using microsatellite markers
Estimation of genetic diversity is an important factor in germplasm conservation and characterization. In rice breeding programs, genetic diversity information on specific regions of genome can be very useful for the application of marker assisted selection (MAS) and for gene mapping. A total of 152 rice lines were considered for breeding programs using microsatellites (SSR) technique. The tota...
متن کاملMapping QTLs for Agronomic Traits in Rice Under Water Stress Condition Using Iranian Recombinant Inbred Lines Population
In the current study, a set of 96 recombinant inbred lines (RIL) at F8, derived from a cross between two varieties, Anbarbu (sensitive to drought stress) and Sepidroud (tolerant to drought stress) were used. The experiment was performed at Gonbad Kavous located in the Golestan province of Iran in 2010–2011 using two augmented designs at normal and stress conditions, separately. The RIL populati...
متن کاملTwo-Stage Genome-Wide Search for Epistasis with Implementation to Recombinant Inbred Lines (RIL) Populations
OBJECTIVE AND METHODS This paper proposes an inegrative two-stage genome-wide search for pairwise epistasis on expression quantitative trait loci (eQTL). The traits are clustered into multi-trait complexes that account for correlations between them that may result from common epistasis effects. The search is done by first screening for epistatic regions and then using dense markers within the i...
متن کاملDetermination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
