优质谷子新品种豫谷15丰产性稳产性分析

Analysis on High-yield and Yield-stability of Good Quality Millet Variety Yugu 15

[目的]评估谷子新品种豫谷15的丰产性和稳产性。[方法]利用品种稳定性参数和高稳系数法,以2009年国家谷子品种区域试验结果为依据,对豫谷15的高产、稳产性进行分析。[结果]用高稳系数法估算豫谷15高产稳产性结果,与通用方法估测的高产稳产性结果相似,豫谷15不仅产量高,而且适应度高、变异系数小、回归系数小、高稳系数大,体现了高产基础上的稳产;中抗谷锈病、谷瘟病,抗逆性强。商品、食用品质兼优,有广泛的开发利用价值。[结论]豫谷15是一个高产、稳产、多抗、适应性强的谷子新品种,适宜在河南、河北、山东夏谷区晚春播或复播种植。

[Objective] The aim was to evaluate the high-yield and yield-stability of good quality millet variety Yugu15.[Method] Based on the results of national millet regional tests in 2009,the high-yield and yield-stability of Yugu15 were analyzed by evaluating stability parameter and high stability coefficient method.[Result] The result of high and stable yield of Yugu15 evaluated by high stability coefficient method was similar to that evaluated by general method.Yugu15 not only had high yield,but also had high fitness,small variation coefficient,small regression coefficient,big high stability coefficient,which showed yield-stability based on high-yield.Yugu15 had middle resistance to Millet rust and Millet blast,and it had strong stress resistance.Yugu15 had good commodity and edible quality,and had wide development and utilization value.[Conclusion] Yugu15 was a good millet variety with high yield,stable yield,multi-resistance and strong stress resistance,which was suitable for late spring sowing or multiple seeding in summer millet area of Henan,Hebei and Shandong province.
