The Agronomic Traits and the Utilization of Dwarf, Large Spike and High Yielding Potential Wheat Breeding Parent SW3243
Abstract: The S×W pattern developed common wheat line SW3243 was one of important parents in Sichuan, its pedigree was 1426/4/IR68-77/YAA//ALD‘S’/3/ YAZ//ST2022/983. SW3243 was high resistance to stripe rust race CYR29 and CYR30, and did not suppress the performance of resistant genes when crossed with other resistant materials. SW3243 contained characteristics of dwarf, more spikelets, large spike, high yield potential and early maturity even in late planting. Lots of new lines had been developed from SW3243 in Sichuan, among them 42 derived lines were attended province and national yield trial respectively, and 7 varieties were released in Sichuan province and 3 were released in national level. The plant area of SW3243 and its derived varieties were totally extended to 4.33 million hectare in Sichuan.
