摘要:

本文阐述了高产抗病小麦新品种新麦57的选育过程,分析其遗传基础。采用高稳系数法对其产量进行稳定性分析,采用变异系数法对其产量三要素进行分析,结果表明:新麦57在3 a试验中,产量均高于对照品种百农207,具有良好的丰产性;高稳系数比对照品种平均高6.86百分点,具有较好的产量稳定性。产量三要素中穗粒数的变异系数低于穗数和千粒重,穗粒数较稳定,不易受环境因素影响,地域差异、土壤肥力等自然条件对新麦57的穗数和千粒重的影响相对较大,在适宜的气候条件和土壤肥力下较易获得更高的穗数和千粒重,从而获得更高的产量,新麦57具有较大的丰产潜力。

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.
