k You 818, a New Indica Hybrid Rice Combination with High Yield, Good Quality and Disease Resistance

K you 818 is a new indica hybrid rice combination with high yield, high quality and disease resistance bred by Lixiahe Agricultural Research Institute of Jiangsu Province. It is exclusively produced and distributed by Nanjing Shenzhou seed Industry Co., Ltd. This variety has applied for national new variety protection and patent, the notice number is: CNA000548E. It was examined and approved by Jiangsu Province in 2001, and participated in the regional test of high yield group in southern rice region in the same year, and the yield per mu reached 660 kg, ranking first in the combination. In 2002, an exception was made to participate in the national southern rice production experiment, which increased by 10.65% over the control mu, ranking first, and was a veritable national champion. At present, it is a new variety with the highest yield and the most prominent combination of high yield and high quality in China. it is the first choice for new hybrid rice varieties to win high yield and help farmers become rich. In 2003, he passed the national trial in the first place, the national trial code: national trial rice 2003055.

The whole growth period of cultivation in Jiangsu is 145 days, which is 4 days later than that of Shanyou 63.

Generally, the effective panicle per mu is 17-180000, the total number of grains per panicle is 160-170, the seed setting rate is about 85%, and the 1000-grain weight is 30 grams. The quality of rice is excellent, and the quality index is 83 points, ranking first in the combination tested. High resistance to bacterial blight, rice blast, sheath blight, strong lodging resistance, high temperature resistance.
