Title: Inheritance and Association of Quantitative Characteristics in Syrian Landraces of Garden peas (<i>Pisum sativum</i>L.)
Abstract: In a study conducted at Dara'a Center of Scientific Agricultural Research, GCSAR, Syria, during two growing seasons 2010–2011 and 2011–2012, 13 pea genotypes were grown in a randomised complete block design with three replications. This investigation aimed to find out the nature and magnitude of genetic variability, correlation and path coefficient of different characteristics. Analysis of variance revealed highly significant differences among genotypes for days to 50% flowering, days to marketable maturity, internode length (cm), pod length (cm), pod width (cm), filling degree, shelling percentage (%), ten-green pod weight (g), biological yield per plant (g), harvest index (%) and pod yield per plant (g). ten-green pod weight, biological yield per plant and pod yield per plant showed high genotypic coefficient of variation accompanied with high heritability and genetic advance as percent of mean indicating good scope for selection. The correlation studies indicated that, in general, estimates of genotypic correlation coefficient were higher than corresponding phenotypic correlation coefficient. Significant and positive associations were observed between pod yield per plant and 10-green pod weight, biological yield per plant and harvest index, suggesting that these characteristics could be considered as major green pod yield contributing characteristics in garden peas. Path coefficient analysis revealed that days to marketable maturity, biological yield per plant and harvest index exhibited the maximum positive direct effect on pod yield per plant indicating the importance of these three attributes while making selection of high yielding genotypes in garden peas.
