Abstract

The experiment was conducted at Zonal Agricultural Research Station (ZARS), Gandhi Krishi Vignana Kendra (GKVK), Bengaluru during 2014-15. Thirty two pigeonpea genotypes were screened for resistance against Fusarium wilt in the sick plots and the same set of genotypes were subjected to rigorous screening under greenhouse conditions by using root dip inoculation technique. Among 32 genotypes, 21 genotypes were showed resistant reaction, 4 were moderately resistant three were moderately susceptible and 6 were susceptible under sick plot conditions at 180 days after sowing. Similarly, only 15 genotypes were showed resistant, 9 were moderately resistant, one was moderately susceptible and 7 were showed susceptible reaction under green house conditions at 60 days after root dipping. Root dip inoculation technique confirmed the wilt response in pigeonpea genotypes within short duration of two months. Therefore the identified technique can be used for large scale screening of pigeonpea genotypes against Fusarium wilt.
