MICROPROPAGATION TECHNOLOGY IN EARLY PHASES OF COMMERCIAL SEED POTATO PRODUCTION

Micropropagation Technology in Early Phases of Commercial Seed Potato Production

Research was carried out on possibilities to improve methods commonly used in commercial potato tissue culture laboratories, predominantly those in Western Canada. The study included: (1) Photoautotrophic micropropagation, (2) Short-term, low temperature (< 12 weeks) storage of plantlets, (3) Production of microtubers (in vitro tubers) and (4) Utilization of microtubers in greenhouse production...

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

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...

Seed Physiology, Production & Technology

Detasseling is used in hybrid corn (Zea mays L.) seed production to ensure harvested seeds have the desired genetic complement. Both mechanical and hand detasseling result in loss of some leaf tissue and plant N. The objective of this study was to determine if seed yield and quality and N content of grain and stover were affected by leaf removal during detasseling. The treatments evaluated were...
