Abstract

A study was conducted at Badnapur in the district of Jalna on the behavior of two hundred and forty-eight pigeonpea germplasm lines representing different levels of resistance to pigeonpea wilt disease. Out of 248 germplasm lines Resistant (R), Moderately Resistant (MR), Moderately Susceptible (MS), Susceptible (S), Highly Susceptible (HS) and Very Highly Susceptible (VHS) reaction was given by 2, 8, 10, 25, 131 and 72 entries, respectively. Germplasm lines GL4 (7088) and GL90 (ICP-8863) expressed significantly highest resistance over the rest of germplasm lines tested. All the intraplot sickness checks at all sites from SCS1 to SCS50 responded with significantly highest wilt (%) and were at par indicating uniform inoculum load throughout the sick plot. In testing stability of resistance in donor lines, it was revealed that 9 donors responded with significantly least wilt (%) having consistent Resistant “R” reaction thereby indicating their stability as resistance donors.
