新疆绿洲甜玉米灰色关联度综合评价

Pessimistic Interrelatedness Quality Synthetic Evaluation on Sweet Corn in Xinjiang Oasis

运用灰色关联度分析法对新疆绿洲农区10个甜玉米杂交组合的9个主要性状间的相互关系进行了研究分析。结果表明,与产量关系密切的是穗粗、穗行数、鲜百粒重、鲜出子率,其次是株高、行粒数、穗位高。研究可为新疆绿洲鲜食甜玉米高产优质栽培提供理论参考。

In this article,with the pessimistic interrelatedness analytic method,the reciprocities between 9 main adult plant traits of 10 hybrid sweet corns in Xinjiang oasis fishery area were analyzed.The result indicated that the traits closely related with yield were thickness of ear,the number of lines on ear,the fresh heavy per hundred grains,fresh seed rate,next were plant height,the grain number per line,ear position.Increasing ear length,the grain number per line,plant height,the height of ear position,the stem thickness could enhance the contents of protein,fat,starch and lysine.
