Association and inheritance of several agronomic characters in four wheat crosses
1986
El-Ajlouni, M.M.
Inheritance mechanisms for 15 plant characters of wheat, Triticum durum Desf. were studied in 3 generations in crosses derived from 4 parents - Hourani, Mexicali 75, Yamuna, and Njoro227, during 1984/85 seasons. Phenotypic associations between grain yield and its components were high, while the morpho-physiological traits have poor positive association with grain yield and its components. BSH values for all traits, except number of spikelets/spike, spike length and flag leaf area, showed low to medium values. High heritability coupled with high genetic advance for some characters, such as total seed number/plant, plant height, main spike seed number and weight indicated that selection for these traits will be valuable. Some characters showed high values for additive gene action indicating that selection for these characters could be practiced in early generations. Hourani X Mexicali 75 showed promising results
