For QTL mapping of related salt tolerance QTLs and determining the contribution of each QTL to phenotypic variation, a population consisting of 96 F2:3 families derived from the cross Kharchia (parent tolerant) and Gaspard (susceptible parent) were evaluated during 2 years. Of the 92 microsatellite markers used to evaluate parents, 32 markers were polymorphic which were used for analysis. Three...
In order to explore the relevant molecular genetic mechanisms of photosynthetic rate (PR) and chlorophyll content (CC) in rice (Oryza sativa L.), we conducted a series of related experiments using a population of recombinant inbred lines (Zhenshan97B x IRAT109). We found a significant correlation between CC and PR (R= 0.19**) in well-watered conditions, but no significant correlation during wat...
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...
The adzuki bean (Vigna angularis) is an important grain legume. Fine mapping of quantitative trait loci (QTL) and qualitative trait genes plays an important role in gene cloning, molecular-marker-assisted selection (MAS), and trait improvement. However, the genetic control of agronomic traits in the adzuki bean remains poorly understood. Single-nucleotide polymorphisms (SNPs) are invaluable in ...
TThis study was undertaken with the objective to determine the association between grain yield and its components and identifying traits have the greatest effects on grain yield of 45 mutant lines from tarom-mahaliin a randomized complete block design with three replications. Analysis of variance showed significant differences among genotypes for all traits. Mean comparison showed that line 2...
Advanced backcross introgression lines (BILs) developed from crosses of Oryza sativa var. Swarna/O. nivara accessions were grown and evaluated for yield and related traits. Trials were conducted for consecutive three seasons in field conditions in a randomized complete block design with three replications. Data on yield traits under irrigated conditions were analyzed using the Additive Main Eff...
Improved eating quality is a major breeding target in japonica rice due to market demand. In this study, we performed genetic analysis to identify quantitative trait loci (QTLs) that control rice eating quality traits using 192 recombinant inbred lines (RILs) derived from a cross between two japonica cultivars, 'Suweon365' and 'Chucheongbyeo'. We evaluated the stickiness (ST) and overall evalua...
To study the genetic basis of heat tolerance at anthesis, a set of chromosome segment substitution lines (CSSLs) derived from Sasanishiki (japonica ssp. heat susceptible) and Habataki (indica spp. heat tolerant) were used for analysis across three high temperature environments. Spikelet fertility (SF), daily flowering time (DFT) and pollen shedding level (PSL) under high temperature (HT) were a...
body weight (bw) is a complex and important economic trait that may benefit from the implementation of marker assisted selection (mas). the objective followed in this study was to identify qtls associated with bw at different ages as distinct traits based on an experimental half-sib cross of japanese quails divergently selected for bw at 4 weeks of age. the body weights at hatch, and as well at...
Chromosome segment substitution lines MBI9804, MBI9855, MBI9752, and MBI9134, which were obtained by advanced backcrossing and continuously inbreeding from an interspecific cross between CCRI36, a cultivar of upland cotton (Gossypium hirsutum) as the recurrent parent, and Hai1, a cultivar of sea island cotton (G. barbadense) as the donor parent, were used to construct a multiple parent populati...
