Qingnan II is the one used by the Qing dynasty No. 2 as the mother, South Guanggui as the father, early breeding hybrid indica varieties. In 1972 and 1973, the ratio of products to their products was increased by 16.2% and 11.2% respectively, compared with that of the control variety. In 1974, they took part in the regional test. The average yield per mu in 20 pilots was 746.9 kg, an increase of 19.9% %. In 1975 and 1976, they took part in the autonomous regional test. The average yield per mu in two pilot years was 784.9 kg and 734.7 kg respectively, an increase of 8.4% and 7.7% respectively over the control variety. Now I have planted more than 5,000 acres in the region, generally yielding four or five pounds. All students
