Abstract

Fourteen isolates of were collected from different locations of mustard growing regions of India and were studied for cultural, morphological and molecular variability at CCS HAU, Hisar. Variability was observed for colony colour, type of growth, diameter of mycelial growth, sclerotia initiation, number and pattern of sclerotia formation among the isolates. Mycelial growth and sclerotia initiation were faster in Bhiwani isolate as compared to others. Bhiwani isolate was found to be the most diverse and had least similarity with Chhanibari isolate on the basis of molecular variability. Hence, morphological and cultural variability observed in the present investigation is by and large strongly correlated to molecular marker based variability.

摘要

从印度芥菜种植区的不同地点收集了14株分离株，并在希萨尔的CCS HAU对其进行了培养、形态和分子变异性研究。在分离株中观察到菌落颜色、生长类型、菌丝生长直径、菌核起始、菌核形成数量和模式的变异性。与其他分离株相比，比瓦尼分离株的菌丝生长和菌核起始更快。基于分子变异性，发现比瓦尼分离株是最多样化的，与昌尼巴里分离株的相似性最低。因此，本研究中观察到的形态和培养变异性在很大程度上与基于分子标记的变异性密切相关。
