EVALUATION OF DIFFERENT SUGAR BEET VARIETIES AGAINST FUSARIUM OXYSPORUM F. SP. BETAE AND ALTERNARIA ALTERNATA

Abstract

Twelve different sugar beet varieties were used to evaluate resistance against Fusarium oxysporum f. sp. betae and Alternaria alternata at Sugar Crops Research Program, NARC, Islamabad during 2012. In case of F. oxysporum only one variety (SD-PAK-01/07) was found moderately resistant, two moderately susceptible (SD-PAK-03/06 and EB-0809), seven susceptible (SD-PAK-04/06, SD-PAK-07/07, SD-12970, EB-0618, EB-0726, Sandrina and Ernestina) and two (SD-PAK-09/07 and California) were found highly susceptible. While in case of A. alternata leaf spots, only two varieties were found moderately resistant (California and Ernestina), three moderately susceptible (SD-PAK-01/07, SD-PAK-09/07 and EB-0809), three susceptible (SD-PAK-04/06, EB-0618 and Sandrina) and four (SD PAK-03/06, SD-PAK-07/07, S-12970 and EB-0726) were found highly susceptible.
