Super Rice King
Zhezao 15 is a new super high-yielding early indica rice line bred by mutation using the super high-yielding gene advantage of Zhe18500. After multi-point trial planting of early rice by Zhejiang Province Academy of Agricultural Sciences, the yield of 667 square meters (1 mu) was generally over 600 kg. The characteristics and advantages of Zhejiang Morning 15 are described as follows:
1. The tillering ability is very strong, and the seed is used less. Effective tillers per plant can reach 12-15 plants, and 1 kg of seeds can be used in every 667 square meters field.
2. Cold tolerance at seedling stage and disease resistance at later stage. Seedling cold strong, can be appropriate early sowing. Late disease resistance, especially strong resistance to rice blast.
3. Panicle big grain many, seed setting rate is high. The panicle length is 23.5 cm, about 250 grains per panicle, more than 300 grains per panicle, seed setting rate is more than 85%, and 1000-grain weight is 26 g.
4. The reproductive period is moderate. The whole growth period of early rice planted in southern double-cropping rice area is generally 110-113 days.
5. Super high yield, rice quality is in wait. Generally 667 square meters can produce 600 kilograms. High rice yield, can be used as edible grain, processed grain and converted into feed grain.
