采用二倍体胚和三倍体胚乳的种子遗传模型及其分析方法，通过2年的试验，研究了玉米籽粒油脂性状之间的胚、胚乳、细胞质、母体效应的相关性及其环境互作的相关性。结果证实，玉米籽粒油分与棕榈酸、亚油酸、α-亚麻酸极显著负相关，与硬脂酸、油酸极显著正相关。进一步研究表明，油分与棕榈酸的胚加性（ rAo ＝-1．000**）、细胞质（rC＝-0．772**）达极显著负相关，油分与硬脂酸的胚加性（rAo ＝0．793**）和细胞质（rC ＝0．887**）、油分与亚油酸（rAoE ＝1．000**）、油分与α-亚麻酸（rAoE＝1．000**）的胚加性互作则呈极显著正相关。脂肪酸组分中，棕榈酸与油酸、硬脂酸与α-亚麻酸、油酸与亚油酸、油酸与α-亚麻酸极显著负相关。棕榈酸与亚油酸、α-亚麻酸，硬脂酸与油酸、亚油酸与α-亚麻酸极显著正相关。进一步分析显示，棕榈酸与硬脂酸的胚乳加性互作（ rAeE ＝1．000**）和母体加性互作（rAmE ＝1．000**）、亚油酸与α-亚麻酸的胚加性互作（rAoE ＝1．000**）达极显著正相关，而硬脂酸与亚油酸的母体加性互作（rAmE ＝-1．000**）、硬脂酸与α-亚麻酸的细胞质（rC＝-0．613**）极显著负相关。油酸与亚油酸（rε＝-0．402**）、亚油酸与α-亚麻酸（ rε＝-0．412**）的相关程度受环境或机误的影响较大。
採用二倍體胚和三倍體胚乳的種子遺傳模型及其分析方法，通過2年的試驗，研究瞭玉米籽粒油脂性狀之間的胚、胚乳、細胞質、母體效應的相關性及其環境互作的相關性。結果證實，玉米籽粒油分與棕櫚痠、亞油痠、α-亞痳痠極顯著負相關，與硬脂痠、油痠極顯著正相關。進一步研究錶明，油分與棕櫚痠的胚加性（ rAo ＝-1．000**）、細胞質（rC＝-0．772**）達極顯著負相關，油分與硬脂痠的胚加性（rAo ＝0．793**）和細胞質（rC ＝0．887**）、油分與亞油痠（rAoE ＝1．000**）、油分與α-亞痳痠（rAoE＝1．000**）的胚加性互作則呈極顯著正相關。脂肪痠組分中，棕櫚痠與油痠、硬脂痠與α-亞痳痠、油痠與亞油痠、油痠與α-亞痳痠極顯著負相關。棕櫚痠與亞油痠、α-亞痳痠，硬脂痠與油痠、亞油痠與α-亞痳痠極顯著正相關。進一步分析顯示，棕櫚痠與硬脂痠的胚乳加性互作（ rAeE ＝1．000**）和母體加性互作（rAmE ＝1．000**）、亞油痠與α-亞痳痠的胚加性互作（rAoE ＝1．000**）達極顯著正相關，而硬脂痠與亞油痠的母體加性互作（rAmE ＝-1．000**）、硬脂痠與α-亞痳痠的細胞質（rC＝-0．613**）極顯著負相關。油痠與亞油痠（rε＝-0．402**）、亞油痠與α-亞痳痠（ rε＝-0．412**）的相關程度受環境或機誤的影響較大。

A seed genetic model with diploid embryo and triploid endosperm was used to analyze embryo ,endo-sperm,cytoplasmic and maternal effects correlations and their G ×E interaction correlations for fat traits on maize kernel ,the results confirmed that significantly negative correlations existed between oil and palmitic acid , linoleic acid and α-linolenic acid,while significantly positive correlations showed between oil and stearic acid ,oleic acid. Further research showed that significantly negative embryo additive correlations ( rAo =-1.000**) and cytoplasm correlations(rC =-0.772**)existed between oil and palmitic acid ,while significantly positive embryo additive corre-lations(rAo =0.793**),cytoplasm correlations(rC=0.887**)existed between oil and stearic acid,and embryo addi-tive interaction correlation between oil and linoleic acid (rAoE =1.000**),oil and α-linolenic acid(rAoE =1.000**). For fatty acid compositions,significantly negative correlations showed between palmitic acid and oleic acid ,stearic acid and α-linolenic acid,oleic acid and linoleic acid,α-linolenic.While significantly positive correlations existed between palmitic acid and linoleic acid ,α-linolenic acid ,the same between stearic acid and oleic acid ,linoleic acid andα-liolenic acid .Further analysis indicated that significantly positive endosperm additive interaction correlations (rAeE =1.000**),maternal additive interaction correlations (rAmE =1.000**)existed between palmitic acid and ste-aric acid,and embryo additive interaction correlation (rAoE =1.000**)between linoleic acid and α-linolenic acid, while significantly negative maternal additive interaction correlation ( rAmE =-1.000**) showed between stearic acid and linoleic acid,and significantly negative cytoplasmic correlation ( rC =-0.613**) between stearic acid and α-linolenic acid.The correlativity of oleic acid and linoleic acid (rε =-0.402**),linoleic acid and α-linolenic acid ( rε =-0 .412**) were easily affected by environment or error .
