Evaluation of lentil genotypes against Fusarium oxysporum f. sp. Lentis under artificial epiphytotic condition

Abstract

Wilt of lentil is a very destructive disease caused by fungus Fusarium oxysporum f. sp. Lentis. In India, lentil crop suffers a great loss due to this disease. The use of resistant variety is one of the best methods of disease management. Therefore, studies were planned to search out the genotypes against Fusarium wilt through sick plot technique. Keeping this point in view, one hundred fifty genotypes of lentil were tested for the resistance against Fusarium oxysporum f. sp. lentis in field condition. It is evident from the result presented in table 2 that out of 150 genotypes, 66 genotypes viz.; RLG-109, VL-138, IPL-316, LL-1136, K-75, RLG(105), PL-101, LL-1187, IPL-532, KLB-104, L-4704, IPL-529, LL-1135, KLS-107, IPL-531, DPL-62, IPL-318, SL-28, PLO-98, L-4702, IPL-219, RLG-112, L-4076, LH84-8, HPLC-649, L-1114, L1161, IPL-215, PLO-097, IPL-319, L-4076, DPL-15, IPL-526, IPL-220, VL-142, DL-11-5, IPL-531, KLS-113, VL-143, IPL-325, L-4588, LL-1231, L-4707, PL-129, IPL-325, IPL-324, PL-117, IPL-529, IPL-319, IPL-513, IPL-521, RLG-147, HUL-57, L-4688, L-4147, IPL-315, VL-134, NDL7-402, L-4076, VL-516, RLG-73, IPL-314, VL-133, VL-515, IPL-526, L-4589 and LH07-27 were found resistant, 37 genotypes were found moderately resistant, 34 genotypes were found moderately susceptible, 9 genotypes were found susceptible and 4 genotypes viz.; RVL-48, L-4590, HUL-57 and RLGF-109 were found highly susceptible. None of the genotypes was found immune against the disease.
