摘要
采用3倍体胚乳禾本科作物种子数量性状遗传模型和统计分析方法,分析了啤酒大麦籽粒的蛋白质含量、淀粉含量、纤维含量、脂肪含量及β-葡聚糖的胚、胚乳、细胞质和母体植株遗传效应及狭义遗传率。结果表明,所测的5个品质性状主要受控于遗传主效应,环境互作效应较小。蛋白含量、淀粉含量、纤维含量、β-葡聚糖含量的表达主要受控于细胞质遗传效应,控制脂肪含量的遗传主效应以母体显性效应为主;蛋白质含量,淀粉含量、纤维含量和β-葡聚糖含量的狭义遗传率分别为69.75%、60.09%、57.69%和61.76%,脂肪含量性状未被检测到显著的狭义遗传率。加性遗传相关分析结果表明,蛋白质含量与纤维含量间存在细胞质、母体加性的完全正相关,蛋白质含量与β-葡聚糖含量,纤维含量与淀粉含量、β-葡聚糖含量存在极显著的的细胞质完全负相关。
In this paper,analysis of embryo,endosperm,cytoplasmic and maternal plant genetic effects and narrow heritability for protein content（ PC）,starch content（ SC）,fiber content（ FC）,fat content（ FATC） and beta glucan content（ BGC） of malting barley were conducted by using a quantitative character genetic model of seeds in the triploid endosperm gramineae of cereal crops and statistical analysis method. It was indicated by the results that the genetic main effects for 5 quality characters（ PC,SC,FC,FATC,BGC） were more important than the environment interaction effects. The main effect was cytoplasmic effect in genetic main effects for PC,SC,FC and BGC,but the FATC was mainly controlled by maternal dominance effect in malting barley. The narrow heritability of PC,SC,FC and BGC traits was 69. 75% 、60. 09% 、57. 69% and 61. 76% respectively,but the significant narrow heritability was not detected on FATC. The additive genetic correlation analysis results showed that there was cytoplasmic and maternal additive perfect positive correlation between PC and FC,and the cytoplasmic perfect negative correlation was extremely significant between PC and BGC,FC and SC,FC and BGC.
