从一个集团选择群体的第二周期随机取样的45个红苕单株,和每一单株的25个放任授粉的后代用以估测7种块根特性的遗传力:苕块重量0.25±0.13;胞间空隙0.70±0.14;干率0.65±0.12;萌芽率0.39±0.14;肉部氧化0.24±0.13;肉色0.53±0.14;和皮层厚度0.25±0.13。胞间空隙具有的中数和众数为约7％的常态分布。干率为具有中数为28.8和众数为27和31％的双众数分布。在干率的表现方面明显地涉及了最少两种遗传体系,一种与桔红色肉部相联系,另一种则与白色肉部相联系。本文是关于胞间空隙、干率和萌芽性的第一次报导。
Forty-five R. solanacearum individuals sampled randomly from the second cycle of a group selection and 25 randomly pollinated offspring per plant were used to assess the heritability of the seven root characteristics: nodule weight 0.25 ± 0.13; cells The interstices were 0.70 ± 0.14; the dry rate was 0.65 ± 0.12; the germination rate was 0.39 ± 0.14; the meat was oxidized by 0.24 ± 0.13; the flesh color was 0.53 ± 0.14; and the cortex was 0.25 ± 0.13. The interstitial spaces have a normal distribution with a median and mode of about 7%. The dry rate is a bimodal distribution with a median of 28.8 and a mode of 27 and 31%. There are obviously at least two genetic systems involved in the performance of dry matter, one associated with orange-red meat and the other with white meat. This article is the first on the intercellular space, dry rate and sprouting of the first report.
