【摘要】 柱型苹果品种选育项目始于1994年,旨在将苹果柱型生长习性与其它优良性状结合起来。结果表明:杂种后代的生长势、早实性,对白粉病、轮纹病和绵蚜的抗性等与杂交组合有关。果实大小、果形、果肉硬度、风味品质、花期和果实成熟期为多基因控制的性状。筛选出了一个柱型基因(Co)的AFLP标记并成功地将其转为SCAR标记,其可以用于柱型苹果杂种的早期选择。几个优系的田间实验正在进一步进行中。更多还原

【Abstract】 An apple breeding program started at Laiyang Agricultural College in1994,aiming at combining columnar growth habit and other desirable characteristics in a new variety.Preliminary observation on the performance of the crossed progenies showed that the growth vigor;precocity;resistances to mildew,ring spot and woolly aphid varied greatly.The fruit size and shape,flesh firmness,eating quality,flowering date and fruit ripening date were apparently polygenic characters.An AFLP marker of Co gene was selected and converted into SCAR marker,which could be employed to detect columnar genotype with higher efficiency.Further trials of several promising selections are under way.更多还原
