Emerald City Broccoli with high yield, excellent quality, resistance, suitable for processing and other characteristics. My company was introduced from Japan in 1995, the rapid promotion in our city, the current cultivation of more than 1,000 acres. First, the characteristics of the varieties of plants more erect, plant height 40-50cm, the degree of 80-100cm, the total number of leaves 22-24, leaf wax more, the largest leaf length 35-45cm, leaf width 25-28cm, all Growth period of 120-130 days.
