Determining the relative contribution of yield components in faba bean using some statistical methods [electronic resource].

Includes reference.

This investigation was carried out at the Agricultural Research Station of Tag El-Ezz. Dakahlia Governorate during 2006/2007 and 2007/2008 seasons to evaluate the performance of eight genotypes of faba bean namely; Sakha 1. Sakha 2. Nubaria 1. Giza 3. Giza 843. Giza 674. Giza 617 and Giza 2. Also. to investigate the relationship between seed yield/plant and its factors using some multivariate techniques namley; correlation. stepwise, multiple liner regression and factor analysis. The results showed that the studied characters were significantly affected by the tested faba bean varieties. Giza 2 was the earliest one concerning number of days to 50% flowering followed by Nubaria 1 and Sakha 2. Sakha 1 variety gave the highest values for number of branches/plant, plant hight, number of pods/main stem and number of seeds/pod followed by Giza 3 and Giza 716. Giza 3 recorded the highest weight of pods, 100 seed ands seed yield/plant followed by Sakha 1 and Giza 716. Multiple linear regression and stepwise analysis agreed upon the number of branches/plant. number of pods/main stem, weight of pods/plant and 100-seed weight as major contributions to seed yield variation.
