Screening of chilli (Capsicum annuum L.) genotypes for morhpological characteristics showing resistance against Fusarium wilt

Abstract

The present investigation was undertaken with an objective to screen thirteen chilli genotypes (two resistant checks; DCL 524 and CCA 4261, two susceptible checks; Punjab Surkh and Punjab Guchedar and nine advanced lines; Sel-7, Sel-11, Sel-36-1, Sel Dev, PC-6, VR-16, C-31-1, ACC-33-1 and Mehma Sarja) against Fusarium wilt to evaluate morphological characteristics in relation to resistance/ susceptibility to this disease at two stages of crop development i.e. 10 DAT and 105 DAT. The morphological characters viz. root length, root girth, fresh and dry weight of root and leaf were more in resistant genotypes whereas number of roots were more in susceptible genotypes at both stages. On the basis of above studies, five advanced lines viz. ACC-33-1, C-31-1, Sel-7, Sel-36-1 and VR-16 were categorized as chilli genotypes resistant to Fusarium wilt
