Potato Seed Supply, Marketing and Production Constraints in Eritrea

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

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...

Constraints to Production, Processing and Marketing of Sweet-Potato in Selected Communities in Offa Local Government Area, Kwara State Nigeria

Offa Local Government Area is one of the major sweet-potato growing areas of Nigeria. Sweet potato is grown mainly on smallholder farms and concentrated particularly in communities in Offa Local Government Area. This study randomly selected 90 small scale farmers purposively from 9 communities to investigate constraints to production, processing and marketing of sweet-potato. Data were collecte...
