The present investigation was undertaken to achieve information on gene action and combining ability in sorghum [Sorghum bicolor (L.) Moench]. experimental material consisted of eleven parents their 28 Line × Tester crosses. evaluation carried out during Kharif, 2020 at Sorghum Research Station, S. D. Agricultural University, Deesa. ratio σ2D/σ2H being more than unity found for days flowering, ...

Stay green is the plant’s ability to sustain photosynthetically functional leaf area for longer periods, even with excessive water stress. This study was done understand gene action that controlled inheritance of stay trait general objective contributing breeding more drought tolerant maize varieties. 10 F1 hybrids from crosses between highly performing and least inbred lines as regards s...

A method for producing high surface area nano-sized mesoporous alumina from inexpensive Iranian kaolin as raw material is proposed. In this method, first, kaolin was purified for purifying Kaolin, High Grade Magnetic Separation and leaching with HCl and chemical bleaching treatment by using sodium dithionite (Na 2 S 2O4 ) as reducing agent in acidic media (H 2SO 4 ) were used. Pur...

Genetic progress in quantitative traits can be improved by understanding how genes interact and estimating the consequences of combining abilities. As a result, randomized block design with three replications was used to conduct forty crossings using line X tester mating ten lines four testers. All qualities were shown highly variable based on ANOVA (analysis variance) results among lines, test...

BACKGROUND The goal of this study was to apply Bayesian and GBLUP methods to predict genomic breeding values (GEBV), map QTL positions and explore the genetic architecture of the trait simulated for the 15th QTL-MAS workshop. METHODS Three methods with models considering dominance and epistasis inheritances were used to fit the data: (i) BayesB with a proportion π = 0.995 of SNPs assumed to h...

In bread wheat (Triticum aestivum L.), crop height is an important determinant of agronomic performance. To map QTLs with additive effects and additive×additive epistatic interactions, 148 recombinant inbred lines and their parents, (‘YecoraRojo’ and Iranian landrace (No. #49)) were evaluated under normal and water deficit conditions. The experiments were carried out on research farms of Mahaba...

The aim of this study was to determine nature and extent of variability parameters and their utilization in barley breeding programme. A total of 45 F1s along with their parents and F2 populations were evaluated in a randomized block design with 3 replications during Rabi (winter season) 2014. The various traits measured were days to 50% flowering, days to maturity, plant height, flag leaf area...

The Booroola fecundity gene (FecB) and growth differentiation factor 9 (GDF9) gene belong to the transforming growth factor β (TGF-β) superfamily. The mutations of these genes have additive effects on the prolificacy in sheep. The aim of the present study was to determine the possible mutations of FecB and FecGH genes in Lory sheep breed of the Lorestan province, Iran. Sixty...

Climate change increases the drought-affected areas, which challenge breeders to develop adaptive and drought-tolerant rice cultivars. The study aimed determine heritability, gene action controlling of various traits in upland F4 populations derived from cross, Sileso (high yielding drought tolerant) × Ciherang (early maturing), obtain high-yielding early-maturing lines. populations, along with...
