Last Updated: 2024/11/06, The main results are as follows: (1) Variety source: it is a medium indica early maturing combination bred by Ⅱ-32A and restorer line Luhui 3028 in Sorghum Research Institute of Sichuan Academy of Agricultural Sciences. (2) characteristics: the plant height of the combination is 99.5cm, the whole growth period is about 150d, it is 5 days longer than the control Shanjing 8, the effective ear per mu is 17-180000, the ear is flat with 142grains, the seed setting rate is 82.9%, and the 1000-grain weight is 25-26g. The field grew neatly and changed color well in the later stage. Resistant to rice blast, leaf blast grade 4, neck blast grade 1-5. Roughness

The main results are as follows: (1) Variety source: it is a medium indica early maturing combination bred by Ⅱ-32A and restorer line Luhui 3028 in Sorghum Research Institute of Sichuan Academy of Agricultural Sciences.

(2) characteristics: the plant height of the combination is 99.5cm, the whole growth period is about 150d, it is 5 days longer than the control Shanjing 8, the effective ear per mu is 17-180000, the ear is flat with 142grains, the seed setting rate is 82.9%, and the 1000-grain weight is 25-26g. The field grew neatly and changed color well in the later stage. Resistant to rice blast, leaf blast grade 4, neck blast grade 1-5. The roughness rate is 82%, milled rice rate is 67.7%, and head rice rate is 55.5%. The appearance and eating quality of Shanzheng No. 8 were better than those of the control.

(3) yield performance: in the provincial regional tests in 1995 and 1996, the average yield per mu was 496.6 kg and 488.94 kg respectively, which was 15.65% and 11.68% higher than that of Shanjing 8 in the same ripening period. In the production test, the average yield per mu was 486.68 kg higher than that of the control by 12.13%.

(4) suitable planting area: this combination has good yield and strong resistance, so it is suitable to be cultivated as early-maturing and middle-season rice in the mountainous area around the basin of our province.
