| 摘 要： | 本文根据我省及黄淮区试、生产试验资料，分析了皖８９２３６小麦的增产潜力、产量三要素通径系数和动态结构，并作了抗逆抗病性模糊评判等，结果表明皖８９２３６产量分布主要集中在５２５０—７５００ｋｇ／ｈａ；随产量水平上升，三要素的总趋势是上升的，但穗粒数在产量水平低于６７５０ｋｇ／ｈａ时上升较快，而成穗数、千粒重则在产量水平高于６７５０ｋｇ／ｈａ时增幅较大；对产量的贡献，成穗数＞穗粒数＞千粒重。三要素间相关系数较大，因而自调能力强，综合抗性好，对白粉、叶锈、叶枯、赤霉等病害中－高抗，抗倒伏，耐青干，稳产性好，适应范围广，是个潜力很大的材料。

| Abstract: | The outstanding wheat cultivar Wan 89236,developed during eight-five years,was studied using variance analysis,path analysis and fuzzy evaluation. The results indicated that the cultivar has high yield potential from 5250 to 7500 kg/ha; 3 yield components tend to increase as the yield up,but grains per ear increases quickly when yield is below 6750kg/ha,while the number of spikes per ectare and 1000 kernel weight are contrary to it;The path coefficient of the number of spikesper hectare (0. 4707)is greater than the others,and there is intensive self-adjusting ability among 3 yield components ;also,the cultivar has medium to high resistance to powdery mildew,leaf rust,head soap and lodging,dry-heat wind etc. It is ofgood yield stability and wide adaptation. |
