Thapa, Author ; M. B. Shrestha, Author ; R. C. Bhandari, Author Pagination: 241-244 p. Languages : English (eng) Keywords: Potato,  genotype,  reducing  sugar,  cold  storage,  composition,  chips Abstract: Potato of five varieties: Kufri Jyoti, Janak Dev, Klwmal Seto, Diseree and Khumal Rato were evaluated during the cold storage at 5-70c,and obsen•ed the changes of reducing sugar up to three months (90 days). Tile proximate composition of fresh potato genotypes were analyzed before storage as moisture content, protein, total ash. total fat, crude fibre and carbohydrate ranged 78.70 to 81.90%. 1.96 tO 2.29%, 0.82 to 1.09%, 0.04 to 0.10%, 0.41 to 0.58% and 14.61 to 17.56% respectively and found no signi[rcmzt difference in their composition. The level of redl}cing sugar ranged from 0.12 I 5% to 0.4424% on the fresh weight basis at tlze time of storage. Tlze score of chips colour was found good in all the varieties of potato before storage. The level of reducing sugar ranged from 0.9326% to 1.2198%. showed lziglz accumulation of reducing sugar in all tlze varieties of potato after three months of storage. Tlze chips prepared from 90 days stored potato were found unacceptable dark brown in colour. Tile level of reducing sugar in all varieties of potato were found in increasing trend i.e. before storage, 30 days of storage, 60 days of storage and 90 days of storage.

Characteristics of Ralstonia Solanacearum Strains of Potato Wilt Disease from Nepal and Thailand / Dhital, S.P. in Nepal Agriculture Research Journal, Vol. 4 (2000/2001)  

Public ISBD [article]  inNepal Agriculture Research Journal > Vol. 4 (2000/2001) . - 42-47 p Title : Characteristics of Ralstonia Solanacearum Strains of Potato Wilt Disease from Nepal and Thailand Material Type: printed text Authors: Dhital, S.P., Author ; N. Thaveechai, Author ; Sundar K. Shrestha, Author Publication Date: 2000 Article on page: 42-47 p Languages : English (eng) Keywords: Key  words:  Bacterial  wilt,  potato,  Pseudomonas  solanacearum,  Ralstonia  solanacearum Abstract: Characterization of strains of Ralstonia solanacearum, the causal agent of potato bacterial wilt disease from Nepal and Thailand was performed based on pathogenicity, biochemical/physiological and serological tests. Fifteen R. solanacearum strains isolated from wilt infected potato plants and tubers grown in Nepal were characterized as race 3, biovar II based on the pathogenicity on different host plants, hypersensitive reaction on tobacco leaf and utilization of some sugars. Results of pathogenicity test show that all strains from Nepal had limited host range. Degree of virulence of all strains varied from high to medium in potato and tomato and medium to low in eggplant. They did not cause wilting in tobacco, pepper and peanut plants. Six strains from Thailand were characterized as biovar II and III. Additionally, comparisons on the physiological, biological and serological characters of seven strains from Nepal and six from Thailand revealed similar characters. Race 3 and biovar II of the pathogen was widely spread over potato growing areas of mid and high hills of Nepal. Both biovars II and III were prevalent in the potato growing areas of Thailand but biovar III was the most dominating one.

Disease-free Pre-Basic Seed Potato Production through Tissue Culture in Nepal / Sakha, B.M. in Nepal Agriculture Research Journal, Vol. 8 (2007)  

Public ISBD [article]  inNepal Agriculture Research Journal > Vol. 8 (2007) . - 7-13 p Title : Disease-free Pre-Basic Seed Potato Production through Tissue Culture in Nepal Material Type: printed text Authors: Sakha, B.M., Author ; GP Rai, Author ; Dhital, S.P., Author Publication Date: 2007 Article on page: 7-13 p Languages : English (eng) Keywords: DAS-ELISA,  meristem  excision,  potato,  pre-basic  seed,  thermotherapy Abstract: Pre-basic seed potatoes are disease free potato minitubers produced by transplanting pathogen free in vitro potato plantlets under protected condition in aphid-proof glasshouse and/or screen house. Double antibody sand witched - enzyme linked immuno-sorbant assay is used to test six major potato viruses, namely PLRV, PVS, PVX, PVY, PVA and PVM. Thermotherapy cum meristem tip excision techniques are used to eliminate these viruses. Virus free in vitro potato plantlets are rapidly propagated by single nodal cuttings on modified MS media. For pre-basic seed production disease free in vitro potato plantlets are transplanted in the sterile sand soil substrate under glasshouse and screen house, once in autumn season and next in spring season. Since 1990, National Potato Research Program has been producing about 200,000 pre-basic seeds annually. So far, PBS of 19 different recommended and released potato cultivars has been produced. Till date 3,465,799 PBS had been produced and 3,217,666 pre-basic seeds distributed to the different seed potato growers groups, District Agriculture Development Offices, government farms/research stations, and NGOs/INGOs for subsequent basic seed potato production. After establishment of tissue culture facilities in National Potato Research Program, the productivity of potato has been increased by 71% due to utilization of pre-basic seed potatoes.

Effect of Chemical Treatments and Storage on Quality of Potato Chips / Gautam, I.P. in Nepalese Horticulture, v. 8/9 ([07/25/2012])

Languages : English (eng) Keywords: Genotypes,  effect  of  storage  on  chips  quality,  potato,  slice  treatment Abstract: Experiments were conducted at National Potato Research Programme (NPRP), Khumaltar (1350 m asl) during the year of 2011 to study the effect of slices treatments with different chemicals before the preparation of chips and effect of different storage methods and days for preparation of chips. Potato cultivars Kufri Chipsona-2 and PRP 25861.1 were used for experimentation to assess the effect of chemicals on chips and chips qualities before storage. Same cultivars were used for different conditions and durations of storage to assess chips quality. Undamaged and apparently healthy tubers of more than 60 gram weight were stored in ordinary room temperature under dark (26.9 ±1.16 o C) and cold store conditions at Balaju for 90 days. Temperature and relative humidity of ordinary storage room was recorded daily during the storage period. Observation was recorded on chips quality parameters like dry matter percentage, specific gravity and reducing sugars and freshly prepared chips qualities (colour, crispness, taste and over all acceptability). The results indicated that slices washed and dipped for 15 minutes in fresh water was found as effective as slice treatment with potassium meta bisulphate (slices dipped for 15 minutes in 0.25%) for preparation of fresh chips before storage. On the other hand, cold stored potatoes for 30 days and on-wards were not suitable for preparation of chips due to the browning of chips as a result of higher reducing sugars. Chips prepared from 75 and 90 days stored potatoes under dark at ambient temperature of genotype respectively Kufri Chipsona-2 and PRP 25861.1 had acceptable chips colour and qualities [article] Effect of Chemical Treatments and Storage on Quality of Potato Chips [printed text] / Gautam, I.P., Author ; M.D Sharma, Author ; Bhim B.
