Study of Some Morphological Traits of Corn Hybrids

In order to assess this potential yield of maize genotypes in drought conditions and review some of the quantitative traits associated with grain yield and selected superior genotypes, 10 corn genotypes with the experimental in 2010-2011 crop year. The analysis of variance showed significant differences between the traits evaluated in terms of stress and there was no tension. Also among the genotypes in terms of all traits there was a significant difference. Figures show that the genetic richness was investigated. Performing factor analysis through principal component analysis, six factors in total 98.74 percent of the changes were justified. The results indicate the importance of factor coefficients of trait selection weight of 500 seeds per genotype is ideal for dry conditions. Also use the correct cross between cultivars with resistance traits and environmental conditions in future studies should be taken into account and such tests at different levels of stress and be conducted on different cultivars.
