Screening of potato (Solanum tuberosum) genotypes for morphology and yield attributes in mid-hill rainfed condition of Uttarakhand

Abstract

Eight new potato (Solanum tuberosum L.) hybrids including two checks (Kufri Giriraj and Kufri Jyoti) were evaluatedat Ranichauri, Tehri Garhwal, Uttarakhand during kharif 2008. Most of the traits differed significantly except shoot numbers hill-1, number of compound leaves plant-1, shoot weight, ‘A’ and ‘B’ grade tubers and specific gravity. Among hybrids, SM/91-1515 gave highest yield and most tolerant to late blight, even at the late stage of the crop. Thus SM/91- 1515 hybrid was found to be suitable for Garhwal Himalayas of Uttarakhand
