Screening of okra genotypes against Fusarium wilt was conducted using 76 genotypes viz., 21 parents, 54 F1 hybrids and one commercial check (MHY-10) in a randomized block design and replicated twice. Analysis of variance revealed significant differences among the genotypes for fusarium wilt disease index. The mean fusarium wilt disease index among the parents ranged from 12.28 (KON-1) to 73.61 (KON-17) Per cent and the parent KON-1 (12.28) is highly resistant to fusarium wilt. The mean fusarium wilt index among the hybrids varied from 10.88 (KON-13 x IC90174) to 59.21 (KON-18 x KON-19) per cent. The hybrids KON-13 x IC90174 (10.88%), KON-15 x IC90174 (11.47%), KON-15 x AAN (13.13%), KON-5 x KON-19(14.02%), KON-14 x IC90174 and KON-9 x KON-19 (15.00%) which showed highly resistant reaction by recording lowest fusarium wilt disease index. However in comparison with the parents and hybrids the commercial check MHY-10 reacted as resistant with 13.93 per cent of fusarium wilt disease index. To conclude from the present findings that, genotypes which showed resistant reaction can be used in further breeding programmes to develop varieties/hybrids resistant against fusarium wilt along with better horticultural traits.
