 ABSTRACT

Studies on screening and evaluation of potato (Solanum tuberosum L.) genotypes for field resistance against apical leaf-curl diseases were conducted at Research Area, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter (Rabi) season of 2012-13. Twenty genotypes of potato were planted on 16 October 2012 in randomized block design with three replicates to screen against apical leaf-curl disease. Infector rows were planted all-round the trial and after every tenth row. Out of 20 genotypes, Kufri Bahar, Kufri Chipsona-2, Kufri Frysona, HIS-98-19, HIS-98-34, HIS-98-55, HIS-98-58, CP 2370, CP 2378, CP 2379 and CP 2390 were found completely free from potato apical leaf-curl disease and considered as highly resistant. Out of these 20 genotypes, eight genotypes/varieties were planted on 16 October 2012 in a randomized block design with three replicates. Infector rows were planted around the plots. Analysis of variance revealed that sufficient variation existed among the eight genotypes for all the characters under study except plant vigour at 60 DAP, leaf area index and foliage senescence. Kufri Badshah showed better performance for most of the growth characters viz. plant height, plant vigour, number of leaves per hill, weight of stem per hill, weight of leaves per hill, weight of foliage per hill and leaf area index. Kufri Pushkar produced significantly maximum total (426.24 q/ha) and marketable yield (397.63 q/ha) closely followed by Kufri Badshah, which were statistically at par. Whitefly [Bemisia tabaci (Gennadius)] population was observed maximum in highly susceptible genotype CP 1588, Kufri Khyati and Kufri Pukhraj. The lower number of whitefly was found in Kufri Bahar and Kufri Pushkar that had lower disease incidence.

Key words:Bemisi tabaci, Percent apical leaf-curl disease, Kufri Bahar, Kufri Chipsona-2
