摘要
利用云南省小麦良种区域试验和生产试验汇总资料,采用多种分析方法对抗条锈病新品种云麦73的丰产性、稳产性及产量构成因素进行了分析比较。相关分析表明,千粒重与产量呈极显著正相关,有效穗数与产量呈显著相关,每穗粒数与产量相关不显著;通径分析表明,千粒重对产量的直接作用最大,其次是有效穗数,每穗粒数对产量的作用不明显,提高千粒重和增加有效穗数是其高产的关键。云麦73号是具有丰产性突出、高产潜力大、综合性状优良的抗条锈病品种,若能选择合适的种植区域和栽培方法,该品种具有良好的应用前景。
Based on the summary data of the regional trials and production trials of wheat varieties in Yunnan province,a variety of analytical methods were used to analyze the high yield potential,yield stability and yield components of a new stripe rust resistant wheat variety Yunmai 73. The results showed that there was a significant positive correlation between the thousand-grain weight and the yield,and the effective panicle was significantly correlated with the yield. The grain number per panicle was not significantly correlated with the yield. The results of path analysis showed that the direct effect of thousandgrain weight on yield was the highest, followed by the effective panicle. The effect of grain number per panicle was not obvious to the yield. The increase of thousand-grain weight and the effective panicle was the key to its high yield. Yunmai 73 is a stripe rust resistant cultivar with high yield potential and good comprehensive traits. With appropriate cultivation method,this variety will have a good application prospect in suitable planting area.
