RELATIVE IMPORTANCE FOR YIELD COMPONENTS IN SOME FABA BEAN (VICIA FABA L) CULTIVARS UNDER DIFFERENT PLANT POPULATION DENSITIES.
Abstract: Two field experiments were carried out at the Agricultural Research Station, Agricultural Research Center (A R C), Giza, Egypt,during two successive seasons (2009/2010 and 2010/2011). The aim of this study was to investigate the effect of plant population densities (17, 22, 27 and 33 plants/m2) ,of three of faba been cultivars (Giza 40, Giza 716 and Giza 843) and their interactions on yield and its components. Also, to investigate the relationship between seed yield and its components using some multivariate procedures as Simple correlation, stepwise multiple linear regression and path coefficient analysis. Results could be summarized as follows:
Giza 716 cultivar surpassed each of Giza 843 and Giza 40 cultivars in plant height, number of branches/plant, number of pods/plant, weight of pods/plant, number of seeds/plant, weight of seeds/plant, weight of 100 seeds, and seed yield kg/fed in the two subsequent seasons and their combined analysis. Increasing plant population densities decreased number of branches/plant, number of pods/plant, weight of pods/plant, number of seeds/plant, weight of seeds/plant, and weight of 100 seeds. While, increasing plant densities produced taller plants.
Results of the interaction between cultivars and plant densities are presented in Table ( 3). Results indicated that all of the studied characters were significantly affected. Except number of branches/plant. Also results cleared that weight of seeds/plant was decreased by increasing plant density for all of the studied cultivars.
Highly significant and positive correlations were found between weight of seed/plant and each of number of branches/plant, number of pods/plant, weight of pods/plant, number of seeds/plant and weight of 100 seeds. On the other hand, plant height was negatively correlated with weight of seed/plant.
Results of multivariate analysis procedures of the studied faba bean cultivars revealed that number of seeds/plant, weight of 100 seeds, weight of pods/plant and plant heights were the most important contributing characters in the total variability of seed yield. These characters have to be ranked the first in any breeding program to improve faba been seed yield/fed.
