Edible Mushroom Disease Control and Introduction of the Green Crown 309 Broccoli Variety

The latest first-generation broccoli hybrid developed using a cytoplasmic male sterile line, a mid-to-late maturing imported variety. It matures uniformly, has broad adaptability and strong disease resistance, and produces attractive heads with high market value. The plant has few side branches and no hollow stems, with long stalks and thick, sturdy florets; the buds are tight, fine and dark green, forming a flat, round head. A single head weighs about 800 g, giving high yield and excellent quality, and it is harvested 80-85 days after transplanting. It is a preferred variety for fresh-vegetable export processing and specialized commercial planting on farms. (Shao Tailiang, Zhejiang Shenliang Seed Industry Co., Ltd., Postcode: 325011)
