Abstract

Fusarium wilt is a serious disease in pigeonpea which causes severe yield loses. Screening of 88
lines along with ICPL 87119 and ICPL 8863 resistant checks for fusarium wilt under field conditions
and artificial inoculation identified 14 lines having 0-20% plant mortality and grouped under 0-5
disease score. PCR reactions using different primers with genomic DNA of these lines resulted in
identification of six resistant sources with specific amplification for resistance to wilt at 920bp with
OPGO8 primer. Considering the wilt reaction and resistance linked RAPD marker, it is possible to
identify the new resistance sources in a short time and they can be utilized in breeding programme
or for direct release.

Keywords
