Selection andCultivation of New Processed-TypeWhite OnionVariety"Keweibai No 3"

Four doses of He-Ne laser irradiation are used to irradiate the seeds of processed white skin onion parent "K6". Aiming at low bolting rate and high dry matter content in the early stage, new varieties are selected through laser irradiation, excellent variation breeding, variety comparison test and production test. A new Onion Variety "Ke Weibai No.3" with high yield, low bolting rate and high dry matter content has been bred after 10 a time. The main characteristics of new onion varieties, such as leaf, plant height, yield and dry matter content have been introduced, as well as the key points of efficient cultivation techniques, such as rotation and field treatment, sowing, seedling, planting, fertilization, irrigation, pest control and harvesting.
