Screening of date palm varieties for resistance against post harvest fruit rot
Keywords:
Date palm, post harvest diseases, resistance, screeningAbstract
The experiments were conducted at Date palm farm, Agricultural Research Station SKRAU, Bikaner during Kharif 2013 and Kharif 2014 to record the incidence percentage of different post harvest diseases on date palm fruits for screening of date palm varieties for resistance. Eight varieties viz., Zahidi, Sayar, Khalash, Nagal Hilali, Ruziz, Khasab, Halawy and Barhee were selected Seven fungal rot pathogens were isolated from infected date plam fruits viz., Botryodiplodia, A. niger, A. flavus, Rhizopus sp., Fusarium sp. and Penicillium sp. In first year of the experiment, none of the varieties were found resistant where as six varieties viz., Zahidi, Sayar, Khalash, Nagal Hilali, Ruziz, and Khasab were found moderately susceptible and two ( Halawy and Barhee ) were found Susceptible. In second year two varieties viz., Khasab, Khalash were found Resistant, where as six varieties viz., Zahidi, Sayar, Ruziz, Zijaj, Nagal Hilali and Halawy were found moderately susceptible and none of the varieties were found susceptible.
