摘  要

謝明憲、王仕賢、林棟樑、王仁晃.2003.甘藍優良品系選拔及組合力檢定。台南區農業改良場研究彙報 42:32~44。

本試驗係以本場所選育出的甘藍自交不親和系為母本,另以臺灣地區選育及自國外引入的抗病及耐熱自交系為父本進行雜交組合,評估雜交品系的結球性及葉球品質等性狀表現,目的在於選育優良組合及進行組合力檢定,以利從中選取一般組合力高的自交系作為親本,加速甘藍育種工作進展。結果顯示“TNSP30-9×TSS23-3-1”F1組合經過夏季及秋季栽培試驗後,在所有供試F1組合中,均有最高的葉球重。組合力分析結果顯示,供試組合母本親在葉球重、可溶性固形物含量及中心柱長度比例等性狀表現遺傳效應,均未達顯著差異水準,顯示母本親間在該等性狀表現差異性較低;父本親中“TSS23-3-1”品系的可溶性固形物含量及葉球重性狀表現在夏秋二季均有較高GCA正效應值,符合育種親本選育目標,但其中心柱長度比例性狀表現之GCA為正效應,是其主要缺失。

Selection of Elite Cabbage Lines and Their Combining Ability Tests

M. H. Hsing, S. S. Wang, D. L. Lin and R. H. Wang

Summary

To select the best hybrids and to determine the general combining ability (GCA) and specific combining ability (SCA) of cabbage are the purpose of this experiment. Twenty-eight hybrids from 4 females and 7 males was used and each male was crossed to all females. The females were selected from the Tainan DAIS. self-incompatibility (SI) inbred lines and the males were selected from National Plant Germplasm Lab of the Agricultural Research institute or abroad black rot-resistant and heat resistant inbred lines. The hybrids were evaluated for maturing uniformity, head-weight, and core length etc. Results showed that the cross“TNSP30-9×TSS23-3-1” has best head-weight in all hybrids in the summer and fall trials, and the male parent lines “TSS23-3-1” has the highest GCA for head-weight and total soluble solid, and has the highest GCA for core length ratio (%) but it is not ordered by consumers.
