Disease-free Pre-Basic Seed Potato Production through Tissue Culture in Nepal

Cell Suspension Culture, Somatic Embryo Genetic and Synthetic Seed Production in Different Cultivars of Potato

Extended Abstract Introduction and Objective: In order to overcome the contamination problems, as well as the usual method of increasing potato through micro tuber, micropropagation has been considered through tissue culture. The aim of this study was to evaluate the callus induction and embryogenesis in potato cultivars using leaf explants. Material and Methods: For this purpose, micropropa...

Seed potato production system in Japan, starting from foundation seed of potato

Potato is one of the staple crops cultivated in upland farming in Japan and is propagated vegetatively by means of tubers. However once infected with diseases, potato yield decreases significantly. And one seed potato can produce approximately only 10 potato tubers. To improve the production system of seed potatoes in Japan, Japanese government established a three-stage propagation system for t...

Early Generation Seed Potato Production & Certification

Potato is one of a number of vegetatively propagated crops. Potato tubers that either are planted whole or have been mechanically cut are the propagating material. The process of vegetative propagation can cause unique problems in maintaining varietal purity and in the management of "seed-borne" diseases. Disease pathogens present in the propagative material will, with all probability, be trans...

Use of local material in seed-bed mixes for production of seedling from true potato seed

Maize seed production communities in hills towards a new path of contract seed production in Nepal

Seed production of farmers preferred improved maize varieties under community based seed production(CBSP) group initiated in the hills of Nepal under Hill Maize Research Project in 2000. Trained members of the community group produce improved seeds identified through participatory varietal selection procedures. Despite quantum jump in maize seed production, 14 tons by 7 CBSP groups in 2000 to 1...
