Abstract

Fusarium wilt is an economically significant disease, which is a major limiting factor in production of lentil crop. In the present investigation a set of 90 lentil germplasm were screened for their reaction towards lentil wilt for two consecutive years and it was found that based on consistent behaviour for two years, a set of six germplasm namely Mpl-04, Mpl-42, Mpl-52, Mpl-55, Mpl-60 and Mpl-74 exhibited less than 1 per cent wilt incidence which were categorized as resistant germplasm. However, 24 moderately resistant, 21 moderately susceptible, 05 susceptible and 09 highly susceptible germplasm could be identified.

Keywords

Lentil, Fusarium oxysporum f. sp. lentis, Resistance, susceptibility

Conclusion

Identification of resistant source for any disease is one of the best methods for management. A set of six germplasm identified here could be a useful resource for using their background in developing elite varieties through conventional breeding. Further, selection of these lines in identification of genetic factor/QTL for wilt resistance will enable their utilization in molecular breeding.
