滇Ⅰ型不育系繁殖栽插密度和基本苗与产量的关系

The relationship between planting density, seedlings per hill and multiplication yield of Dian type Ⅰ cyto-genetic male sterile line

通过对黎榆A繁殖田母本不同栽插密度和不同基本苗数的结果分析:表明穗实粒数、结实率以母本株行距13.2 cm×13.2 cm,2苗/穴栽插最高。不同栽插基本苗之间产量差异极显著,不同栽插密度之间、不同栽插基本苗数×不同栽插密度之间产量差异不显著;黎榆A繁殖母本栽插以株行距13.2 cm×13.2 cm,2苗/穴栽插最佳。

The relationship of planting density (PD), seedling per hill (SPH) and multiplication yield of Liyu A was studied .The results showed that could producr higher yield with the highest number for filled grains per panicle , seed-set rate under the female planting pattern of a spacing of 13.2 cm×13.2 cm.by two SPH.The SPH effected multiplication yield of Liyu A significantly,neither do PD and SPH/PD.
