peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

Product quality is a high priority for the beef industry because of its importance as a major driver of consumer demand for beef and the ability of the industry to improve it. A 2-prong approach based on implementation of a genetic program to improve eating quality and a system to communicate eating quality and increase the probability that consumers' eating quality expectations are met is outl...

high molecular weight (hmw) glutenin sub-units and baking quality related traits were studied in 49 iranian wheat landraces. the protein content ranged from 11.2% to 13.55%, and sds sedimentation volume varied between 40 and 60 milliliters. high molecular weight glutenin electrophoresis profiles revealed that at the glu-a1 locus, the frequency of null allele was higher than sub-units 1 and 2*. ...

The eating quality of cooked rice is important and determines its market price and consumer acceptance. To comprehensively describe the variation of eating quality in 183 rice germplasm accessions, we evaluated 33 eating-quality traits including amylose and protein contents, pasting properties of rice flour, and texture of cooked rice grains. All eating-quality traits varied widely in the germp...

Cotton is an important cash crop. Mining for quantitative trait loci related to yield and fiber quality traits using association analysis has many advantages for cotton research. In this study, 170 simple sequence repeats (SSRs) and 258 sequence-related amplified polymorphisms (SRAPs) were used to analyze the association of 3 yield component traits and 5 fiber quality traits of 55 Gossypium bar...

Lameness is an important factor for culling animals. Strong legs and feet improve herd life of dairy cows. Therefore, many countries include leg and feet conformation traits in their breeding programs, often as early predictors of longevity. However, few countries directly measure lameness related traits to include these in a breeding program. Lameness indices in 3 different lactations and 5 le...

Traditional methods of genetic improvement have yielded long-term, significant improvement in traits relating to production efficiency and overall carcass quality; traits like growth rate, feed conversion, leanness and loin muscle area. These methods require widespread data collection and analysis for continued success. Traits associated with end product or consumer product quality have not rec...
