糯玉米全息区域优势的探讨

采用4个糯玉米自交系,对其当代的形态特征、生理特征和物质积累进行调查研究,证明中部区域有明显优势。糯玉米自交系果穗不同部位的籽粒对后代的形态特征、生理特征和物质积累影响是不同的,中部籽粒后代表现出明显的遗传优势。果穗不同部位的籽粒杂交后代,中部籽粒杂交后代比群体平均值增产22.85％。上述结果不仅对糯玉米全息区域优势作出证明,而且为糯玉米定域选种提供理论依据。

Study of Glutinous Maizes Section Advantage of Bioholoscope

Selecting four varieties of glutinou maize self-bred line, this experiment focused on the character of current generation s shape, philology and calculation of substance . It was proved that glutinous maize self-bred line have middle-section-advantage. The seeds from different parts of corn war are different in the progeny's characteristics of shape, philology and calculation of substance. The middle seeds have evident genetic potential . The middle part's hybrid progeny's yield was 22. 85% higher than that of average yield of maize populations. The conclusion not only testifies that the glutinous maize self-bred line has section-advantage bioholoscope but also supplies ground for bioholoscope for process of specific selection.
