Last Updated: 2024/11/06, The main results are as follows: (1) Variety source: Hongyou X is a Mianyang College of Economics and Technology, which is composed of the self-fertile male sterile line Hongai An and the CDR22 bred by the crop Research Institute of Provincial Academy of Agricultural Sciences. (2), characteristic: the whole growth period is 146 days, which is one day longer than that of Shanyou 63. The plant height is 109.8 cm, the ear length is 25.8cm, each ear has 138.8 grains, the seed setting rate is 86.07%, and the 1000-grain weight is 29 grams. The brown rice rate is 79.6%, the milled rice rate is 72.6%, the ratio of length to width is 2.9, and the rice quality is better than that of the pair.

The plant height is 109.8 cm, the ear length is 25.8cm, each ear has 138.8 grains, the seed setting rate is 86.07%, and the 1000-grain weight is 29 grams. The rate of brown rice is 79.6%, the rate of milled rice is 72.6%, the ratio of length to width is 2.9, and the rice quality is better than that of the control. The results of resistance identification showed that leaf blast was 3-7, neck blast was 5-7, and the resistance was stronger than that of the control.

(3) yield performance: in the multi-site experiment in 1996, the average yield per mu was 577.5 kg, which was 6.12% higher than that of Shanyou 63; in 1997, the urban trial in Mianyang and Deyang simultaneously took part in the urban trial in Mianyang, and the yield per mu in Mianyang was 583.9 kg, which was 6.34% higher than that of the control. In 1998, the average yield per mu was 556.8 kg, 6.69% higher than that of the control, and the average yield per mu in two years was 570.35 kg, 6.51% higher than that of the control. In the regional test of Deyang City in 1997, the yield per mu was 559.31 kg, 6.06% higher than that of the control. In 1998, the yield per mu was 569.75 kg, 10.26% higher than that of the control, with an average yield of 564% per mu in two years. 53 kg, an increase of 8.16% over the control, and a yield of 544.07-603.6 kg per mu was 8.43-8.7% higher than that of Shanyou 63.

(4) cultivation key points: timely early sowing, cultivating multi-tiller and strong seedlings, basic seedlings 8-120000 / mu, heavy bottom and early topdressing, reasonable cooperation of N, P, K, increasing application of organic fertilizer, shallow water irrigation, timely drying, timely prevention and control of diseases and insect pests.

(5) suitable planting area: suitable for planting Shanyou 63 in Mianyang and Deyang of our province.
