A preliminary study on potato cultivars was undertaken at Hattiban Research
Farm Khumaltar, Lalitpur (1340 masl) during the years 2008/09 and 2009/10
to compare the responses of different advanced potato cultivars for their
tolerance against moisture stresses. Completely rain-fed, rice-straw mulching
and frequently irrigated conditions were considered as the moisture treatments
in the trial. Among the assessed clones, CIP 394003.161, CIP 392243.17, CIP
391058.35 CIP 392242.25, Khumal Seto-1, CIP 378711.7, Ca x 27/40-7, CIP
396011.47, Primicia, CIP 391598.75, LBr 40, L 235.4, CIP 394007.55, Kufri
Chipsona-2, NPI-106 and Ca x LBr 40.6 were found performing better than the
check variety Kufri Jyoti in completely rain-fed conditions. In frequently
irrigated treatment, clones CIP 391011.47, Ca x LBr 40.6, CIP 378711.7 and
LBr 40 were superior, whereas in the mulching treatment, clone LBr 40
performed the best followed by 394003.161, Ca x LBr 40.6, CIP 391011.47,
Kufri Jyoti, CIP 392250.56, Primicia, CIP 391598.75, CIP 392236.6, Khumal
Seto -1, CIP 389746.2, 27/40, Des x LBr 43.18, CIP 800947 and 391058.35
respectively in assessed phenotypic, yield and its attributes compared to Kufri
Jyoti and Desiree. This result clearly indicated that the overall performance of
the clone was more under genetic control rather than the environment factors.
Based on the preliminary results, the best performing clones will be further
assessed in multi-locational varietal trials of National Potato Research
programme in the future.
