| Abstract: | An attempt to develop bread wheat for high yield, good adaptation and resistance to diseases through shuttle breeding was made in Sichuan, which is a great province in southwest China with a geographical diversity. The plants of the F 1s, which originated and were selected from the complex crosses by using three or four parents, were grown in winter at Panzhihua, a city in southwest region of the province, with 26 5 degree north latitude and warmer climate than other two sites. The F 2 plants of this crosses were grown and selected at Maerkang, a city in northwest region of this province, with 31 9 degree north latitude and an elevation of 2700m. The successive generations were grown and selected at Qionglai, a city in Chengdu plain which is a region with developed agriculture. The results indicate that the shuttle breeding at the three cities is an effective method to develop bread wheat with high yield, extensive adaptation and good resistance to main diseases in this province. |
