【摘要】:【目的】為了闡明ahFAD2基因的遺傳規(guī)律及其與種子油酸含量的關(guān)系,探究油酸含量與主要性狀的相關(guān)性!痉椒ā坷肅APS標(biāo)記對(duì)141份江蘇地方品種的ahFAD2基因位點(diǎn)進(jìn)行檢測(cè)!窘Y(jié)果】25份材料ahFAD2A位點(diǎn)為野生型,116份材料ahFAD2A位點(diǎn)符合448GA的突變類(lèi)型,ahFAD2B基因只存在野生位點(diǎn);突變型位點(diǎn)所占的比率在交替亞種中遠(yuǎn)高于連續(xù)亞種;油酸含量均值在具有突變型位點(diǎn)花生中顯著高于具有野生型位點(diǎn)花生;花生油酸含量與亞油酸含量有極顯著的負(fù)相關(guān)關(guān)系!窘Y(jié)論】本研究認(rèn)為ahFAD2A等位基因位點(diǎn)與花生種子油酸含量有極顯著的相關(guān)關(guān)系;普通型花生中含有較多的中等油酸含量的ahFAD2A-m。
[Abstract]:[objective] to elucidate the inheritance of ahFAD2 gene and its relationship with oleic acid content in seeds. To explore the correlation between oleic acid content and main characters. [methods] CAPS markers were used to detect the ahFAD2 loci of 141 Jiangsu landraces. [results] the ahFAD2A loci of 25 materials were wild type and 116 ahFAD2A loci were consistent with 448GA. There were only wild loci in HFAD2B gene. The percentage of mutant loci in alternate subspecies was much higher than that in continuous subspecies, and the mean oleic acid content in peanut with mutant loci was significantly higher than that in groundnut with wild type loci. [conclusion] in this study, there was a significant correlation between ahFAD2A allele and oleic acid content in peanut seeds, and ahFAD _ 2A-m, which contained more moderate oleic acid in common peanut, was found to be significantly correlated with the content of linoleic acid in peanut seed. [conclusion] in this study, there is a very significant correlation between ahFAD2A allele locus and oleic acid content in peanut seeds.
