a 7×7 complete diallel cross experiment was performed to study the genetic relationship of grain yield and some agronomic traits in rice. analysis of variance showed significant differences among genotypes for all traits. results of correlation analysis showed that rice grain yield was positively and significantly correlated with by (rp = 0.81, rg =0.55), hi (rp =0.35, rg =0.79), np (rp = 0.80,...

A rice GWAS panel of 281 accessions of japonica rice was phenotypically characterized for 26 traits related to phenology, plant and seed morphology, physiology and yield for 2 years in field conditions under permanent flooding (PF) and limited water (LW). A genome-wide analysis uncovered a total of 160 significant marker-trait associations (MTAs), of which 32 were LW-specific, 59 were PF-specif...

Super sweet corn breeding must develop hybrids that fully meet the expectations of market. In this sense, determination keytraits for selection sweetcorn genotypes is a fundamental condition success. The objective work was to identify key traits promising and contrasting super corn. experiments were carried out in Guarapuava (PR), two sowing dates. Seventeen related yield quality ear evaluated....

Bread wheat is a leading cereal crop worldwide. Limited amount of superior allele loci restricted the progress of molecular improvement in wheat breeding. Here, we revealed new allelic variation distribution for 13 yield-related traits in series of genome-wide association studies (GWAS) using the wheat 90K genotyping assay, characterized in 163 bread wheat cultivars. Agronomic traits were inves...

Maize grain yield and related traits are complex and are controlled by a large number of genes of small effect or quantitative trait loci (QTL). Over the years, a large number of yield-related QTLs have been identified in maize and deposited in public databases. However, integrating and re-analyzing these data and mining candidate loci for yield-related traits has become a major issue in maize....

Characterization of genetic variability in a population is pertinent as genetic diversity within population and within species determines the extent of improvement achieved through crop improvement 8 methods. One hundred ninety six F recombinant inbred lines (RILs) of tef, developed by single-seed descent method from a cross between two tef varieties DZ-01-196 and DZ-01-2356, were evaluated to ...

To investigate some quantitative and qualitative traits of genotypes a field study was performed as augmented experiment consisting four checks (Sadri, Koosha, KS21676 and KS21682) and138 genotypes. Vegetative, morphological and agronomical characteristics as well as traits related to pod and seed were studied. Statistical analysis showed that number of seeds per plant and plant height had the ...

One of the most important purpose in breeding program is increasing grain yield per hectare. Using selection indices is the most effective methods of selection for simultaneous improvement of grain yield and related traits, which often have a quantitative inheritance. In this study, 29 rice genotypes (9 parents and 20 progenies) were evaluated. The numbers of filled grains in panicle and panicl...
