ferent alternatives for defining a strategy. The screened population size has been reported in simulation studies Designing a highly efficient backcross (BC) marker-assisted selecas the most important factor affecting the efficiency of tion (MAS) experiment is not a straightforward exercise, efficiency being defined here as the ratio between the resources that need to MAS (Zhang and Smith, 1992...

This study was conducted to evaluate the heritability methods, genes number equations and comparison between them, as well multivariate analysis of cotton yield its components traits in two crosses G.85 x TNB G.86 Suvin. Broad sense (BSH) using Mahmud & Kramer (1951), Burton Weber Moorthy (1952), Modified Briggs Krowles (1967), Mather Jinks (1971), Lawrence (1973) Kotecha Zimmerman (1978) n...

Drought stress (DS) is one of the most critical environmental abiotic stresses for wheat production in arid environments. Selection high-yielding genotypes tolerant to DS can play a significant role mitigation negative impacts associated with DS. In present study, generation means analysis (GMA) was used study performance two crosses under well irrigation (WI) and deficit [cross I (Line 44 × Sh...

Cultivated soils often are either deficient or possess toxic concentrations of one or more mineral elements that adversely affect emergence, growth, maturity, production potential, and/or nutritional quality of common bean (Phaseolus vulgaris L.). Our objective was to study the inheritance of resistance to soil Zn deficiency. The resistant `Matterhorn' was crossed with the susceptible 'T-39'. T...
