Inheritance of colony morphology and growth rate of Phytophthora parasitica

Growth rates of zoospore progenies of A1 6133C1 and A2 6133S1 isolates of Phytophthora parasitica were relatively uniform and similar to their respective parent. However there was a continuous quantitative variation in growth rate in progenies of selfed oospores. The character of colony pattern also showed variation in oospore progenies but not zoospore progenies. Results of the study suggest that heterozygous polygenes were involved in determining growth rate and colony morphology of these fungi and support the hypothesis that species of Phytophthora are diploid during the vegetative phase

Abstract

Growth rates of zoospore progenies of A1 6133C1 and A2 6133S1 isolates of Phytophthora parasitica were relatively uniform and similar to their respective parent. However there was a continuous quantitative variation in growth rate in progenies of selfed oospores. The character of colony pattern also showed variation in oospore progenies but not zoospore progenies. Results of the study suggest that heterozygous polygenes were involved in determining growth rate and colony morphology of these fungi and support the hypothesis that species of Phytophthora are diploid during the vegetative phase
