Background: Lentil wilt is one of the most important diseases of lentil directly contributing to the yield losses of the crop. It is caused by Fusarium oxysporum f. sp. lentis which shows the great genetic and morphological diversity.
Methods: Present investigation was conducted during 2017-2019 with 22 isolates of the pathogen, collected from lentil grown areas of Uttarakhand and Uttar Pradesh to explore genetic and morphological variability employing eight ISSR and five SSR primers.
Result: The isolates showed huge morphological variability based on the color, pigmentation and shape of conidia. Study on molecular variability revealed the versatility in the genome of different isolates of pathogen. The diversity among the isolates of pathogens collected from Uttarakhand and Uttar Pradesh was also evident. Generated work on genetic and morphological variability and the population diversity among the different isolates of the pathogen impact on developing ideal disease management strategies.
