| 摘 要： | 小麦籽粒表面皱缩的遗传力很低,仅为18.67％,易随栽培条件而发生变化,宜改善栽培条件增加其充实程度。腹沟比率的遗传力较高,品种(系)为56.15％,杂种为59.88％。说明腹沟比率的遗传性较稳定,不易受环境条件的影响。可选用腹沟丰满的亲本组配、选育成籽粒饱满的品种。

| Abstract: | When the heritability for shrivelling of the kernel surface is lower (about 18.67%),the condition of the kernel changes easily changes with that of the cultivating conditions. lt is good for increasing the grainfilling degree under good cultivation conditions. When the heritability of the ratio of grooves is higher (varieties about 56.15% and hybrids about 59.88%), the kernel is not easily influenced by the environmental factors,so,by selecting varieties of plump, grooved kernels to cross, we get varieties of plump seeds. |
