the mode of agronomic traits inheritance was investigated in safflower (carthamus tinctorius l.) in drought stress as a new report. five generation including p1, p2, f1, f2 and f3 that derived from the cross of il.111 (drought sensitive) ×mex.22-191 (drought tolerance) were used in a randomized complete block design with two replications. generation mean analysis was used to estimate genetic pa...

background and objectives: septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph s. tritici) is currently the most serious disease of wheat worldwide. this study was established to determine the function of resistant genes of m. graminicola to find out the number of genes corresponding in resistant reaction and also to estimate the genetic parameters of resistance. mater...

The idea that symmetry in facial traits is associated with attractiveness because it reliably indicates good physiological health, particularly to potential sexual partners, has generated an extensive literature on the evolution of human mate choice. However, large-scale tests of this hypothesis using direct or longitudinal assessments of physiological health are lacking. Here, we investigate r...

Fruit shape index (round shape) and seed size have important effects on pumpkin yield. To investigate these traits to create the most desirable state, a cross was made between two cultivars. This study aimed estimate main gene (additive, dominant di-genic epistasis) determine mode of inheritance for fruit by generation mean analysis. Six generations, namely P1, P2, F1, F2, BC1, BC2 from Zucchin...

Improving tomatoes keeping quality is crucial for reducing post-harvest losses. Knowledge of heterosis, and combining ability a prerequisite breeding high yielding good shelf life heterotic hybrids. An investigation was undertaken with each 3 lines, testers, 9 hybrids to identify desirable parents crosses 20 fruit biochemical, morpho-physiological, yield traits elucidate the nature gene action ...

As a result of two crosses among three local varieties wheat, five populations (P1, P2, F5, F6 and F7) were used as parents grown during successive seasons; 2016/2017 2017/2018. To estimate types gene action (e.g., mean effects, additive, dominance, additive × dominance dominance), formulas developed from with algebraic solution, proof, mathematical proof. Besides, to test adequate simple addit...

An experiment was carried out with North Carolina Mating Design II (NC II) derived F1 progenies along parents to know nature of gene action in regulating early maturity, yield and contributing traits. The principal objective this research identify best specific cross combinations based on combining ability analysis estimation heritability. Hybrids their were arranged a 8 by partially balanced l...
