Identification of heat tolerant, virus resistant candidate potato varieties for cereal based cropping system through participatory varietal selection approach

Abstract

12 heat tolerant, low tropical virus resistant potato CIP clones were evaluated to select candidate varieties that can be planted 15-30 days earlier than normal season in north Indian plains of Haryana. Regarding this research trials were conducted in three districts Karnal, Narnaul and Sirsa in rabi (winter) season of 2021. Out of 12 clones, 11 are red skin whereas clone 4621 has white skin tubers. Kufri Pukhraj, Kufri Lima, Kufri Khyati and one red skin variety Kufri Uday were planted as control. The experiments were planted in randomized block design with three replications. Planting was done in the first week of October almost 20 days earlier than normal season planting. Trials were dehaulmed at 75 days after planting in all the locations. Morphological and yield parameters were recorded and statistically analysed. In all the locations, the highest marketable and total tuber yields were recorded in variety K. Lima. It was statistically at par to clone 4611, 4620, K. Pukhraj and clone 4613. Among the locations, Sirsa was found most suitable place for table potato cultivation followed by Narnaul and Karnal. Two clones 4614 and 4616 found suitable for processing. Participatory varietal selection for tuber yield and market acceptability was done at Sirsa however, organoleptic test was conducted at Sirsa and Narnaul. Based on yield and market acceptability, K. Lima was preferred by stakeholders followed by clone 4621 and 4611. Among clones, 4621 was preferred by stakeholders for its good taste.
