to identify qtls controlling grain yield and yield components, an f2 population consisting of 188 plants derived from the cross between two rice pure lines, binam and kadous, were grown in research field of faculty of agricultural sciences, university of guilan, rasht, iran, in 2008, and were recorded for 9 important traits related to grain yield. to construct linkage map, 85 marker of ssrs and...
Th is research was carried out to identify quantitative trait loci (QTLs) controlling yield and yield components in rice using 196 F2:4 lines derived from a cross between two rice varieties of indica, Sepidrood and Gharib. Quantitative trait loci analysis using composite interval mapping was carried out by 105 SSR and 111 AFLP markers. Results showed that 8 chromosomes contain 28 regions (QTLs)...
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...
Effective panicle number, grain number, and grain weight are the three components of rice yield, of which grain number shows the highest variation and makes the largest contribution to yield output.Rice panicle number per plant is a grain yield component that directly influences rice yield. The identification of the genes controlling panicle number will play a vital role in high-yield rice bree...
salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...
five genotypes of chickpea as a half diallel crossed with each other, in 2008, 5 parents and 10 progenies were planted as randomized complete block design and some traits including days to podding, basal pod height, number of pods per plant, number of double seed pods per plant, number of single seed pods per plant, number of empty pods per plant, seeds per plant and seed yield per plant were e...
in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
The use of fertilizer results in tall rice plants that are susceptible to lodging and results in reduced plant yields. In this study, using chromosome segment substitution lines, we identified an effective quantitative trait loci (QTL) for culm strength, which was designated STRONG CULM2 (SCM2). Positional cloning of the gene revealed that SCM2 was identical to ABERRANT PANICLE ORGANIZATION1 (A...
Total spikelet number per panicle (TSN) is one of the most important traits associated with rice yield potential. This trait was assessed in a set of 334 chromosomal segment introgression lines (ILs: BC(3)-derived lines), developed from new plant type (NPT) varieties as donor parents and having the genetic background of an indica-type rice variety IR64. Among the 334 ILs, five lines which had d...
