Abstract:

This article elaborated on the breeding process of high-yield and disease resistant wheat variety Xinmai 57,analyzed its genetic basis. The high stability coefficient method was used to analyze the stability of its yield,and the coefficient of variation method was used to analyze the three factors affecting the yield of Xinmai 57. The results indicated that in the three-year trials,the yield of Xinmai 57 was higher than the control variety Bainong 207,indicating high yield. The high stability coefficient was 6.86 percentage points higher than the control variety,indicating good yield stability. Among the three factors affecting the yield,the coefficient of variation of grain number per ear was lower than that of ear number and thousand-grain weight. The grain number per ear was relatively stable and not easily affected by environmental factors. Natural conditions such as regional differences and soil fertility had a relatively large impact on the ear number and thousand-grain weight of Xinmai 57. Therefore,suitable climate conditions and soil fertility are more likely to achieve higher ear number and thousand-grain weight,thereby achieving higher yield. Xinmai 57 has great potential for high yield.
