  The present investigation was undertaken to calculate the genetic variability and heritability of desirable physiological traits of wheat (Triticum aestivum L.). Forty-two F1 populations of Triticum aestivum L. were planted in the field and studied for variation and heritability. The variance calculated pointed out that phenotypic traits were significant (P<0.01) for such physiology traits as plant height, superoxide dismutase, catalase, peroxidase, relative water content, membrane stability index, and K+/Na+ ratio. Partitioning of the variance component estimated that the environment had its main impact on the performance of traits like plant height, catalase, and relative water content, while superoxide dismutase, peroxidase, membrane stability index, and K+/Na+ ratio were genetically influenced. Considering the wide variability and high heritability calculated, progress could be expected from selection based on catalase, membrane stability index, and K+/Na+ ratio.

  Interrelationships between yield and its components were determined by genotypic correlation and path coefficient analysis in ten soybean varieties. The results indicated that seed yield plant–1 was positively and significantly associated with all parameters studied. The results also showed that pods plant–1 has maximum positive direct effect on yield plant–1. It was followed by 100 seed weight and seeds pod–1. Plant height had negative direct effect on yield plant–1. It was concluded that pods plant–1, seeds pod-` and 100 seed weight were the main yield components.
