Rice eating and cooking quality is largely determined by starch physicochemical properties. The diverse accessions in the USDA rice mini-core collection (URMC) facilitate extensive association analysis of starch physicochemical properties with molecular markers specific to starch biosynthesis related genes. To identify significant trait-marker associations that can be utilized in rice breeding ...

In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

the inheritance of cold resistance was evaluated at the germination stage in crosses between seven rice genotypes as half diallel. analysis of variance indicated that there were highly significant differences among the genotypes, general combining ability (gca) and specific combining ability (sca) for percentage of reduction in radicle length (rl), percentage of reduction in plumule length (pl)...

Selection in breeding programs can be done by using phenotypes (phenotypic selection), pedigree relationship (breeding value selection) or molecular markers (marker assisted selection or genomic selection). All these methods are based on truncation selection, focusing on the best performance of parents before mating. In this article we proposed an approach to breeding, named genomic mating, whi...

The rice flower carp ( Cyprinus carpio ) is an important fish in integrated rice-fishery farming. Here, we performed the first genome-wide association study (GWAS) for seven growth traits (including body mass, total length, height, width, caudal-peduncle depth, and eye spacing) 200 samples using 369,688 high-quality SNPs 42,225 indels obtained by double-digest genotyping-by-sequencing (ddGBS). ...

pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. the objective of the current study was to review the genetic b...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...
