breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...

Many plant breeding trials often include a large number of genotypes with possibly no repeated field plots. Ineffective control of field variation could result in an inflated residual variance and/or biased estimation/prediction of genetic effects. Three hundred thirty seven (337) multi-parental spring wheat (Triticum aestivum L.) F2 hybrids were grown in two locations in South Dakota without r...

Drought stress is one of the leading constraints to wheat (Triticum aestivum L.) production globally. Breeding for drought tolerance using novel genetic resources is an important mitigation strategy. This study aimed to determine the level of drought tolerance among diverse bread wheat genotypes using agronomic traits and proline analyses and to establish correlation of proline content and agro...

introduction drought stress as the most important abiotic stress plays an important role in yield reduction of crops worldwide. considering the extends and problems caused by the moisture stress, agronomic and breeding strategies in reducing yield loss are essential. in this regard, the identification and selection of effective characteristics of wheat under drought stress in increasing yield, ...

The main objective for plant breeding is to increase genetic diversity. Mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. The present research was aimed to compare efficacy of different doses of Gamma rays (150, 200, 250, 300 and 350 Gy and zero dose control) on the sesame morphological ...

Advanced backcross introgression lines (BILs) developed from crosses of Oryza sativa var. Swarna/O. nivara accessions were grown and evaluated for yield and related traits. Trials were conducted for consecutive three seasons in field conditions in a randomized complete block design with three replications. Data on yield traits under irrigated conditions were analyzed using the Additive Main Eff...

in order to study of variation and relationships between morphological traits with yield and its components in three grain sorghum cultivars (kimia, sepideh and payam) and nine promising lines (mgs1-mgs9) received from seed and plant improvement institute, an experiment was conducted as randomized complete block design with four replications in birjand agricultural research station, in two grow...
