Screening of cauliflower germplasm against Sclerotinia rot

The technique used in screening of different lines/varieties involved placing of equal bits of infected leaves of the susceptible variety on the host plant along with a drop of water. The technique was modified by first initiating the infection on a known susceptible variety, Pusa Snowball K-1, in order to maintain equal inoculation load. Sixty nine varieties/lines were screened against Sclerotinia rot. Winter cauliflowers, namely, Janavon, EC 103576, EWAWH and EC 177283 were found to be resistant and can be used as donors in resistance breeding.
