Genetic Components for Physiological Parameters Estimates in Bread Wheat (Triticum aestivum L.)
Journal Title: Annual Research & Review in Biology - Year 2015, Vol 7, Issue 3
Abstract
Aims: The specific objective of this study was to estimate the genetic components for some physiological parameters to use in breeding programs. Place and Duration of Study: The present research was conducted in the Experiments Farm at University Putra Malaysia (UPM) during crop season 2010-2011. Methodology: Eight bread wheat cultivars were used as parents and crosses for a half-diallel among these wheat cultivars were made in the Agriculture and Natural Resources Research Center of Sistan-Iran and genotypes were arranged as a Completely Randomised Block Design at research farms of university Putra Malysia. Results: The combining ability analysis of variance showed that both general (GCA) and specific combining ability (SCA) variances were highly significant for all the characters except chlorophyll content for SCA, indicating the importance of both additive and non-additive gene effects. Chamran for relative water content and grain yield was the best combiner and the most narrow sense heritability belongs to stomatal conductance. Conclusion: The eight wheat traits analyzed in this study were under dominance gene effects, Chamran with large, positive and significant GCA effects could be used as parent with desirable genes for genetic.
