Yield is the most important and complex trait for the genetic improvement of crops. Although much research into the genetic basis of yield and yield-associated traits has been reported, in each such experiment the genetic architecture and determinants of yield have remained ambiguous. One of the most intractable problems is the interaction between genes and the environment. We identified 85 qua...
Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...
Since cucumber is one of the most economically important horticultural crops, production of hybrid seeds is very important for obtaining a profitable fruit yield. Detecting the best combination of the parents is one of the most important stages in each breeding program. By selecting parents with high heterosis in their progenies, breeders will be able to generate hybrids with high yield. This s...
to estimate the genetic parameters for production and reproduction traits in holstein cows, information from 15 herds recorded by animal breeding center of iran during 1980 – 2004, were employed. estimations were made using restricted maximum likelihood method under an animal model ranging df-reml and matvec software. estimates of heritabilities for yield traits were moderate and ranged from 0....
this research was designed to identify garlic (allium sativum l.) bolting clones and determining the relationship between their morphological traits and bolting capacity by using statistical methods of analysis of variance, comparison of means, correlation coefficients, factor analysis, stepwise regression, path analysis and cluster analysis. traits including flowering ability, number, length a...
introduction barely (hordeum vulgare) is the fourth most important cereal after wheat, corn and rice. regarding the role of breeding to increase barley grain yield a large number of studies have been done in different countries. however, a few studies have been performed across golestan province, in iran. therefore, this study was conducted to know what barley traits have changed with grain yie...
Lolium perenne L. (perennial ryegrass), and Lolium multiflorum Lam. (annual or Italian ryegrass), differ in several traits related to seed yield. Generally, L. multiflorum spikes are larger than L. perenne spikes, and have more spikelets, more florets per spikelet, larger seeds and awns. The greater number of spikelets and florets and larger seeds are associated with higher seed yield in L. mul...
Half-sib mating is an appropriate approach to estimate additive variance component of quantitative traits. This research was conducted to estimate genetic parameters of physiological traits and their response to drought stress in Dactylis glomerata. Twenty five half sib families derived from poly cross of 25 parental genotypes were evaluated under two moisture environments (normal and drought c...
Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...
For the purpose of graphical analysis and estimation of genetic parameters related to yield and its components, six tobacco genotypes was crossed in half -diallel mating design. In this study, the F2 progenies and their parents were evaluated in a randomized complete block design with three replications. The results of analysis of variance indicated a significant difference between genotypes fo...
