2、0001),同時也是高遺傳貢獻(xiàn)率位點(R2>10%),2個位點至少在兩個環(huán)境中穩(wěn)定表達(dá);檢測到313個質(zhì)構(gòu)性狀顯著關(guān)聯(lián)位點,其中31個極顯著關(guān)聯(lián)位點,46個高遺傳貢獻(xiàn)率位點,11個位點至少在兩個環(huán)境中穩(wěn)定表達(dá)。同時,發(fā)掘了5個質(zhì)構(gòu)性狀主效關(guān)聯(lián)位點,如3B染色體上黏聚性關(guān)聯(lián)位點Kukri_c13329_800等。本研究所得到的這些標(biāo)記為在分子水平上研究饅頭品質(zhì)性狀提供了有價值的參考。關(guān)鍵詞饅頭比容饅頭質(zhì)構(gòu)單核苷酸多態(tài)性標(biāo)記全基因組關(guān)聯(lián)分析顯著關(guān)聯(lián)位點中圖分類號:TS201.1文獻(xiàn)標(biāo)識碼:AGenome-WideAssociationAnalysisbetweenS
