| 摘 要： | 分析了20个高粱杂交种脂肪含量的杂种优势及相关性,为优质高粱杂交种选育提供理论依据。利用近红外谷物分析仪分析20个高粱杂交种及亲本的品质性状,使用DPS对各品质性状的杂种优势和相关性进行分析。各品质性状间杂种优势的总趋势是:单宁总淀粉脂肪蛋白质,蛋白质和脂肪的杂种优势以负向优势为主,总淀粉和单宁的杂种优势以正向为主;高粱籽粒中脂肪含量和单宁含量之间达到极显著正相关水平,总淀粉和其他品质性状之间都达到极显著负相关水平;蛋白质含量与低亲、中亲和高亲值都呈不显著正相关,脂肪含量与低亲值呈不显著负相关、与中亲值和高亲值均呈极显著正相关,总淀粉含量与低亲值和中亲值呈极显著正相关、与高亲值呈不显著正相关,单宁含量与低亲、中亲和高亲值均呈极显著正相关。高粱籽粒中单宁含量和总淀粉含量杂种优势较强,脂肪含量和蛋白质含量优势较弱,单宁含量和脂肪含量正相关,总淀粉含量和其他品质性状负相关,脂肪含量遗传易受高亲影响,总淀粉含量易受低亲影响,单宁含量与双亲关系均很密切。

| Abstract: | The heterosis and correlation of lipid content of 20 sorghum hybrids were studied to provide a theoretical basis for high quality sorghum breeding. The quality traits of 20 sorghum hybrids and their parents were analyzed by using near infrared grain analyzer, and the heterosis and correlation of sorghum quality traits were analyzed by DPS. The trend of heterosis among quality traits was tannins>total starch>lipid>protein. The heterosis of protein and lipid were mainly negative, while total starch and tannins were mainly positive. The correlation between lipid and tannin was significantly positive, but the correlations between starch and other quality traits were significantly negative. Protein content had no significantly positive correlation with values of low parent, mid-parent and high parent. Lipid content had no significantly negative correlated with low parent value; while it had significantly positive correlation with mid-parent value and high parent value. Total starch content had a significantly positive correlation with low parent value and mid-parent value except for high parent value. Tannins content had a significantly positive correlation with low parent value, mid-parent value and high parent value, respectively. The tannin content and starch content had higher heterosis in sorghum grain, and protein and lipid had lower heterosis. The tannin and lipid were positively correlated. Total starch and other quality characters were negatively correlated. In the genetic, the lipid content was susceptible to high
value parent and total starch content was susceptible to low value parent, while the tannin content was very close with parents. |
