Title : Selection of late-blight resistant high yielding potato cultivars for central terai under rice-based cropping system Material Type: printed text Authors: Shrestha, S.L., Author ; R. L. Sah, Author ; Khatri, B.B., Author Pagination: 154-160 p. Languages : English (eng) Abstract: Potato (Solanum tuberosum L.) is an important winter vegetable crop in central terai. As compared to India (19.0 t/ha), the productivity of this area (16.59 t/ha) is quite low. The major contributing factors of low productivity are lack of high yielding and late blight resistant varieties. Tubers of 16 cultivars; 4 released check cultivars, 12 superior cultivars from Initial Evaluation Trial in the past were planted in Kartik and grown during winter season in BS 2066 and 2067 in RARS Parwanipur in rice-based cropping system. Experiment was laid out in RCBD with four replications. Tubers were planted on ridges in 60x25 cm spacing fertilized with 1000:100:60 kg NPK + 15 ton compost per hectare. Result showed that cv. Andinita (22.64 t/ha) which had significantly higher yield as compared to the rest of the cultivars and having resistant to late-blight disease was selected and recommended for cultivation in central terai. It was followed by CIP 389660.9 (21.25 t/ha) and CIP 388764.26 LB (19.09 t/ha) having fairly resistant to late-blight showed superior performance should be further evaluated in the farmers' field condition. These three cultivars had increased tuber yield by 25.9%, 18.2% and 6.2%, respectively.

Title : Some Local Potato Cultivars and their Reaction to Viruses Material Type: printed text Authors: Khatri, B.B., Author ; Surendra L. Shrestha, Author Publication Date: 2004 Article on page: 19-21 p Languages : English (eng) Keywords: Local cultivars, potato, tuber yield, virus diseases Abstract: ABSTRACT
Potato Research Programme (PRP) started initial studies of local potato cultivars since 1988/89 in
Nepal, to understand the plant and yield characteristics of these cultivars and to explore potato
cultivars diversity in the country. More activities on germplasm collection, characterization and
performance evaluation were carried out at Khumaltar. Twenty-one local cultivars collected from
different parts of the country were evaluated and compared with check varieties. The studies were
carried out in the laboratory of PRP, Khumaltar for identification and rating of these cultivars
for virus diseases. The presence of different viruses was observed in almost all cultivars tested.
However, the degree of infection was different. The tuber yields of almost all tested stocks were
found infected by virus diseases and as a result, a large number of small sized tubers per plant
were produced. However, combined results of tuber characteristics showed that cultivars Farse
White, Rosita, Khumbule and Lumle Red were superior to Kufri Jyoti in tuber yields over the years.Link for e-copy: http://elibrary.narc.gov.np/?r=73

Ojha, Author Publication Date: 1997 Languages : English (eng) Keywords: Cultivar, diffused light, potato, storability, temperature Abstract: The storability of eleven different Potato cultivars was assessed under diffused light storage (DLS) system. The growth and yield performance of the stored tubers were determined under field condition. Field performance in warm environment of locally multiplied seed stored under DLS indicates that cold-storage is not always necessary. Among the eleven clones, only CIP 800936 and Kufri Dewa had good storage quality under diffused light condition for 3.5 months with

Lorenzen, Author ; B. P. Mainali, Author Pagination: 217-220 p. Languages : English (eng) Keywords: husbandry, potato tuber moth, system analysis Abstract: Twelve varieties of potato in Sankltu and Mulpani and 6 varieties in Panchkhal were found
cultivated in the intellSive potato cultivated areas of Kathmandu valley. Potato cultivars,
Cardinal, Desiree, Kufri Jyoti and NPI /06 were common varieties to all localities. Cardinal
was the most preferred variety. Potato tuber moth (PTM), both in the standing crop and in the
storage was the most imponant biotic factor depleting the harvest. Synthetic chemical pesticides
like methyl parathion, de/tamethrin, dich/orvos, and dimethoate were used as foliar spray on the
standing crop. To mitigate PTM in the stored potatoes either shade dried botanicals like
Animesia mtd China berry or synthetic chemical insecticides like methyl parathion or
dimethoate or dichlorvos or malathion dust were used. Pesticide management of PTM and
diseases in potato crop involved an expr;nse of as low as 0.5% of the cultivated cost (Mulpani)
to as high as 15% (Sankhu and Panchkhal) of the total cost of cultivation. The farmers preferred
red skinned PTM resistant varieties.Link for e-copy: http://elibrary.narc.gov.np/?r=499 System Analysis of Potato Tuber Moth, Pestilence in the Potato Crop Husbandry in Kathmandu Valley [printed text] / Joshi, S.L., Author ; Khatri, B.B., Author ; Shrestha, S.L., Author ; J.
