     To improve a complex characters such as grain yield with low heritability, indirect selection through other characters and selection index based on different effective traits were used. For this purpose, 96 F3 families derived from Roshan and Kavir crossing, together with parents, F1 and F2 progenies were cultivated. In lattice design with 2 replications under drought stress conditions in ...

Rice is one of the most important food crops, thus identification of definitive traits on the yield can be used in breeding programs. In order to determine the best suitable morphological markers for selection of superior genotypes, seeds of 15 rice genotypes including 5 varieties (namely: Binam, Dasht, Neda, Mashhad Domsiah and IR62871-175-1-10) and their 10 F1 hybrids of corresponding variate...

Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...

Agropyron is one of the most resistant plants to biotic and abiotic stresses. It plays an important role in forage yield in rangelands. Genetic variability based on different markers is the important step in crop improvement. In order to evaluate the genetic variation of different Agropyron species based on morphological and chemical traits, this experiment was carried out in the Agriculture an...

Genetic diversity is the basis of breeding studies in many plant species and is one of the most important indicators for selecting parents. The aim of this experiment was to investigate the genetic diversity of tall fescue (Festuca arundinacea) using agronomic traits such as plant height, spring growth score, days to flowering, days to pollination, flag leaf length and width, panicle length, we...

  Application of selection index for screening desired plants based on complex quantitative traits can be more effective than direct selection. This study was conducted using an F2 rice population consisting of 87 plants derived from a cross between two cultivars Gharib and IR28. The purpose was to establish suitable selection indices for increasing yield and its related traits in research farm...

Breeding programs strategies depends on genetical mechanism of selection traits. In the present research, generation mean analysis with joint scaling test was performed to determine the gene action. F1, F2 and F3 generations, derived from Roushan and Kavir cross along with their parents were sown in a partial Lattice design with two replications under stress condition at the research field of S...
