大豆品種改良

Abstract

大豆品種改良計畫目標為選育耐病及高產大豆品種，以提高單位面積產量及降低生產成本，穩定農民收益。本年度試驗結果摘要如下：(1) 已完成12 組雜交組合獲得347 粒F1種子。(2) 進行雜交後代F2 至F6 世代分離與培育，並從F6 世代選拔288 個優良單株。(3)株行試驗汰劣擇優選留41 個晉級。(4) 大豆品系試驗則以TS07-03S、TS06-23S、TS06-08S、TS05-10S、TS07-16B 及TS06-28B 表現較佳，產量高於對照品種。(5) 區域試驗則以TS04-09S 及TS04-37B 表現較佳，產量高於對照品種。 The purpose of this breeding program is to develop new soybean varieties with high yield and resistance to diseases to reduce the cost of production and to stabilize farmer's income. The results in 2018 were summarized as follows: (1) A total of 347 F1 hybrid seeds were obtained from 12 new cross combinations. (2) In the propagation and selection trails, bulk and SSD method were applied to propagation F2-F6 generations, and 288 superior single plants of F6 generations were selected. (3)In the plants-to-row trial, 41 promising strains with good performance were selected. (4)The line yield trial showed better performance with TS07-03S, TS06-23S, TS06-08S, TS05-10S, TS07-16B and TS06-28B, and the yield was higher than that of the check variety. (5) In the regional yield trial of soybean, TS04-37B and TS04-09S were higher yield than check variety.
