Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability. Determining of the combining ability and genetic variance components is one of the most important stage in breeding program of maize inbred lines. For this purpose, the number of 25 early maturity lines with two testers (k1263/1 early and late A679) crossed...

Increasing grain yield is the most important goal in any breeding program. Since yield is a complex trait and involves several quantitative components with low inheritance, its direct evaluation is not usually sufficient and therefore it is suggested that its components be investigated instead. The objective of this study was grouping 60 inbred lines along with four check cultivars of wheat fro...

In this experiment 36 accessions of seven species of Brassica genus were evaluated under field condition (for study of genetic variation) and under laboratory condition (for study seedling drought tolerance) in 2012 at Isfahan university of technology research farm. The statistic design in field was completely randomized block with three replications. Results of field assessments were suggestiv...

In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...

    Sesame is one of the oldest and most important oilseeds in Iran and the world due to its nutritional value. In the present study, 25 sesame landraces collected from different regions of the country were evaluated in terms of phenological, morphological and physiological traits in Urmia climate. The ANOVA results showed that there was a statistically significant difference between the landra...

Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...

thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...
