| 摘 要： | 据分析，旱地小麦品种的生育期、每公顷最高茎数、容重与产量的相关性较强；穗粒数和千粒重是影响小麦产量的关键因素，两者与产量的直接通径系数分别为9．568165和9．949188；旱地小麦穗粒数和千粒重的负相关性较强，协调两者的关系是该区小麦育种的关键。

| Abstract: | According to analysis,the growth period,the maximum stem number per hectare,unit weight of dry-land wheat varieties had strong correlation with wheat yield.The grain number per spike and 1 000-seed weight were the key influencing factors on wheat yield,and the direct path coefficients of them with yield were 9.568 165 and 9.949 188 respectively.The grain number per spike and 1 000-seed weight of dry-land wheat had strongly negative correlation,so coordinating their relation was the key of wheat breeding in ... |
