冬小麦产量与群体整齐度遗传分析
|
摘要
文章以12个冬小麦品系为试验材料,收获后分析其产量性状、农艺性状和群体整齐度。探究有显著差异性状遗传力及群体整齐度对产量及产量构成影响。结果表明,穗长整齐度和穗粒数整齐度与小麦产量及千粒重显著相关。育种过程中,通过提高冬小麦穗长和穗粒数整齐度增加冬小麦产量是有效途径。
In this experiment 12 varities(or lines) of winter wheat were chosen as materials and the accessions for measurement of yield, yield components, agronomic traits and population uniformity of every trait were harvested at the maturing stage. The impacts of agronomic traits and population uniformity on yield and yield components were observed and the relationship of heritability of traits with significant differences and population uniformity was researched. The results showed that there were significant correlations between population uniformities in spike length and numbers of grain per spike with wheat yield. A efficient way to improve the yield of winter wheat by increasing population uniformities of spike length and numbers of grain per spike in the process of breeding was revealed.
