Screening of black pepper (Piper nigrum L.) germplasm for resistance to foot rot disease caused by Phytophthora capsici Leonian

Abstract

Studies were conducted at Calicut (Kerala) to locate sources of resistance among 491accessions of cultivars, 691 hybrids, 124 wild accessions and 182 Karimunda and 60Kottanadan selections of black pepper (Piper nigrum) using stem inoculation technique againstfoot rot disease caused by Phytophthora capsici. One hybrid (Acc. 1375), two wild accessions(Accs. 3160 and 3260) and four Kottanadan selections (2466, 2471, 2515 and 2433) werepromising with disease index 1 and no external lesion after inoculation of the pathogenunder greenhouse conditions.
