Seed potatoes of the Sebago cultivar were produced in Queensland from a single, pathogentested tuber by glasshouse and field multiplication. The seed potatoes, up to seven generations after release from the glasshouse, were compared in four, yearly, yield experiments with imported certified seed potatoes and in three experiments with locally saved seed. The crops produced from seed grown in Queensland yielded as well as, or better than, crops produced from both imported and locally saved seed. No serious disease problems arose in the production of the seed at various sites. Yields were satisfactory and commercial seed potato production in Queensland seems feasible. Two crops a year can be produced providing fresh seed for year round potato production.

Seed Potatoes

The yield of seed size tubers was assessed in five standard potato cultivars (Cardinal, Multa, Ailsa, Heera, and Dheera) in relation to dates of dehaulming (65, 70, and 80 days after planting) in a Seed Potato Production Farm, Debijong, Panchagarh during 1996-97 and 1997-98. Dehaulming at 70 days gave maximum seed size tubers (19.75 t/ha ≈ 76%) but significantly identical to 75 days (19.56 t/ha ≈70%) and 80 days (18.69 t/ha ≈ 63%). Considering all the parameters studied, the performance of Heera proved to be best among the cultivars grown. Among the cultivars, the maximum seed tuber yield was recorded from Cardinal at 80 DAP followed by Heera and Cardinal at 70 DAP, Dheera and Ailsa at 75 DAP. In general, most of the cultivars gave the maximum seed tuber yield when the crop was dehaulmed at 70 and 80 DAP and the lowest from 65 DAP. Key Words: Dehaulming, potato, seed production.

This study established the level of technical efficiency and its determinants among the informal and formal seed potato producers in the southwestern highlands agro - ecological zone of Uganda. A multi- stage sampling procedure was employed to select 636 households (499 informal seed producers and 137 formal seed producers) from which data was collected for two seasons using a semi - structured questionnaire. Data was analyzed using the stochastic frontier approach with a one - step approach. Maximum likelihood estimates for the efficiency parameters showed that both informal and formal seed potato producers were not fully efficient. The mean technical efficiency for informal and formal seed potato producers was 8 1 .4 and 80.4 percent respectively. In terms of yield loss, informal and formal seed potato producers respectively lost an average of 981 and 1,208 kg/acre of seed potato tubers due to inefficiency factors . Specifically, off- farm income source, scale of production, seasonal variation, access to extension services and seed producer being male positively influenced informal seed producers’ technical efficiency while producers’ level of education and seed potato variety diversity negatively influenced their efficiency. For formal seed producers, technical efficiency was influenced positively by producers’ education and negatively by household size. The study suggests that there is an opportunity to improve technical efficiency of informal and formal seed producers by 19 and 20 percent respectively. Therefore, this calls for increased investment in developing and promoting high yielding varieties, provision of extension services, input intensification and addressing gender issues in seed potato production in the context of limited arable land .

Представлены результаты исследований производства семенного картофеля в условиях Алтайского края. Дана оценка отечественных сортов картофеля репродукции элита по производственным показателям и по фитосанитарному состоянию клубней к моменту их посадки. По каждому заболеванию, зафиксированному в Алтайском крае, выделены наиболее устойчивые сорта.The research findings on seed potato production in the Altai Region are discussed. The domestic potato varieties of elite reproduction are evaluated according to their production indices and phytosanitary condition of tubers at planting time. The most disease resistant varieties have been identified for each disease recorded in the Altai Region.
