Genetics of slow rusting resistance in field pea.

      Аннотация: The present investigation entitled "Genetics of slow rusting resistance in field pea" was carried out with a view to analyze the inheritance pattern of components of rust resistance and yield and yield traits in pea (Pisum sativum L.). Using first order statistics (the generation means analysis and the protection experiment) and the second order statistics (the heritability, genetic advance, phenotypic correlation and path-coefficients). Based on above information one can elucidate the nature of gene action involved in governing the expression of components of resistance called slow rusting components. Slow rusting components are those components which slow down the epidemic buildup of the pathogen despite a compatible interaction between the host and the pathogen and are quantitative in nature. Further, the findings of the work presented in this manuscript may serve as a sound tool to formulate the appropriate breeding strategy for the improvement and management of pea crop against the rust disease.
