| 摘 要： | 谷类作物种子的不同部分,在遗传学上互有不同,可归纳为:(1)种皮和果皮,母体组织,具2N染色体数;(2)胚,子代组织,具2N染色体数;(3)胚乳,子代组织,具3N染色体数。本文讨论了上述差异与种子性状遗传研究的关系,并对在胚和胚乳性状上可能存在的母体效应、细胞质效应和核基因效应,提出了相应的遗传学鉴定方法。

| Abstract: | For the seed of cereals, the differences among following categories in generation and ploidy can be observed: (1) seed coat and pericarp, maternal tissue, with 2N chromosomes; (2) embryo, offspring tissue, with 2N chromosomes; (3) endosperm, offepring tissue, with 3N chromosomes. In this paper, the connection of above situation with the inheritance research of seed traits was demonstrated. The genetic method for distingushing the maternal effect, cytoplasm ef- fect and nuclear genic effect, which may exist for embryo and endosperm traits, was pres- ented. |
