甘藷新育成品系之塊根收量及粗蛋白質含量穩定性之研究

Abstract

本研究係利用甘藷品系比較試驗三個地區二年所得之資料，統計分析甘藷塊根收量、粗蛋白質含量及塊根乾物量等三項性狀，在不同環境下品系間的穩定性。 據綜合變方分析結果，在所研究之塊根收量、粗蛋白質含量及塊根乾物量等三種性狀之環境間、品系間及品系與環境之不同而有不同之表現。 The data of root yields, % crude protein content and dry matter yields obtained from advanced trials of newly developed sweet potato entries grown in three locations over a period of two years were subjected to stability analysis. The results of the combined analysis of variance for root yields, % crude protein and dry matter yields indicated that the mean squares for entries (or variety), environments and entries x environment interaction were all highly significant.
