三種育種法以兩個水稻雜交組合來比較其選拔效率,每組合之三個育種法均開始於相同F2集團所選拔出之單株,有二個育種法係來自譜系法,其中一個是在F3早世代行產量試驗以選拔系統(譜系法1),另一個不在早世代行產量選拔(譜系法2),兩者F4、F5世代均以譜系法行之,單種子後裔法是由F2單株各逢機取一粒種子以培育F3集團,同法產生F4集團,F5世代培育成系統,每組合在F6及F7世代以譜系法1、譜系法2及單種子後裔法所選出之品系,行產量試驗。
F3世代譜系法1之系統其產量顯著高於譜系法2之系統,但其後裔在F5世代譜系法1所選出之品系與譜系法2所選出之品系間產量差異不顯著,即早世代基於產量之選拔其效率較低,三種育種法所選出之品系經F6及F7之產量比較試驗結果差異不顯著,單種子後裔法所選出之品系至少不遜於譜系法選出之品系,據本試驗之結果,能節省人力物力之單種子後裔法是值得利用於水稻雜交育種。
Three methods including, two pedigree and a single seed decent method were compared for selection the effectiveness of two rice cross combinations. Three methods were started from the same selected F2 plants in each cross combinations. In the frist method grain yield were tested from the F3 lines (pedigree 1, pd 1) from the F4 generations the ordinary method was used. Second method were followed tradisional pedigree method (pedigree 2, pd 2). For the single seed descent F3 and F4 population were come from a single seed which selected from the F2 and F3 plants (SSD). In the SSD method, the F5 lines were produced from the seeds of individual F4 plant. In F6 and F7 generations yield were compared in each cross of pd 1, pd 2 and SSD lines.
From the experimental results indicated that grain yield among F6 and F7 lines were no significant difference when three methods were used in both crosses. Grain yields of F5 selected lines were no significant difference between pd1 and pd2 method even though in pd1 method the F5 lines were selected from the high yield lines of F3. Thus there were no significant effect of selection in early generation of F3. This result concluded that there were no significant differences by using those three methods in selection. However, the SSD method gave advantage of saving labors and more efficient for land utilization.
