Screening of Chickpea Germplasm and Advance Breeding Lines against Chickpea Wilt

Abstract

The present study aimed to explore the screening of chickpea germplasm and advance breeding lines against chickpea wilt. Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceri (Foc) is one of the economically important vascular diseases affecting the crop at any growth stage. Early wilting causes 77- 94 per cent losses while late wilting causes 24- 65 per cent loss. To identify the resistance source against Fusarium wilt disease, an experiment was conducted in wilt sick plot using Randomized complete block design with two replications. Screening of 168 germplasm lines and 36 advanced breeding lines against Fusarium wilt caused by Fusarium oxysporum f sp. ciceri were conducted during Rabi, 2022-23 in wilt sick plot at RARS, Vijayapur, Karnataka along with a susceptible check (JG 62) and resistant check Super Annigeri (SA-1) in two replications. Among 168 germplasm lines, 10 lines (GPM 99-25, GPM 99-75, GPM 99-80, GPM 99-85, GPM 99-97, GPM 111-8, GPM 111-13, GPM 111-82, GPM 111-100 and GPM 111-101) were resistant, 78 lines were moderately resistant, 78 were susceptible and remaining were highly susceptible to Fusarium wilt disease. Among 36 advanced breeding lines, seven lines were resistant, 17 lines were moderately resistant and 12 lines were susceptible.
