本紅豆雜交育種目的在選育豐產、質優、籽粒大、色澤佳、適合加工、結莢位高、適合機械收穫之優良新品種，以供農民秋裡作栽培。本年度 (1) 100 年秋作進行10 個組合雜交共獲得900 粒F1 種子，並於101 年春作培育其F1 世代。(2) 100 年秋裡作計培育F2 世代10 個組合及F4 世代10 個組合，101 年春作計培育F3 世代10 個組合。(3) 株行試驗，100 年秋裡作於F5 世代2,580 個品系中選出100 個優良品系。(4) 第一年品系試驗計有100 品系參試，100 年秋作在公頃籽粒產量方面,以C 組之KA96-05-31 品系之3,803 公斤表現最佳，較高雄9 號之2,698 公斤增產41.0%。在百粒重方面, 以D 組之KA96-08-176 品系之20.4 公克表現最佳，較高雄9 號18.8 公克增加1.6 公克。綜合評估選拔KA96-05-31 等32 個品系供101 年秋裡作進行第二年品系試驗之材料。第二年品系試驗，在公頃籽粒產量以A 組以KA95-05-269 品系之3,619 公斤表現最佳，較高雄9 號之2,556 公斤增產41.6%。B 組以KA95-07-257 品系之3,445公斤表現最佳，較高雄9 號之2,383 公斤增產44.5%。(5) 新品系區域試驗，公頃籽粒產量有KA94-03-1、KA94-05-4 表現最佳，分別為4,193 公斤、3,900 公斤，較對照高雄9 號之3,464公斤增產21.0、12.6%。
The purpose of adzuki bean cross breeding is to develop new cultivars with high yield, good quality, large seed, bright red seed for process and high pod site for mechanical harvest that were suitable for the cultivation in the south of Taiwan. The experimental result was summarized as follow:: 1) A total of 900 F1 hybrid seeds were obtained from 10 cross combinations in the fall crop season of 2011,and were propagated F1 generation in the spring crop season of 2011. 2) In the propagation and selection trials, bulk method was applied to propagating F2-F4 segregative generations in the fall crop season of 2011 and the spring crop of 2012, respectively. A total of 1,838 superior single palnts in F4 generation were selected in the fall crop season of 2011. 3) In the plant-to-row trial, there were 100 fixed lines in F5 generation were selected depend on their performance in the fall crop season of 2011. 4) In the first-year lines trial, KA96-05-31 line of C group had the highest seed yield among 102 tested lines in the fall crop season of 2011, which was 41.0% higher than check variety, Kaohsiung9. KA96-08-176 line of D group had the higher 100-seed weight among 102 tested lines in the fall crop season of 2011, which was 1.6g higher than check variety, Kaohsiung 9. In the second-year lines trial, KA95-05-269 line of A group had the highest seed yield among 18 tested line in the fall crop season of 2011, which was 41.6% higher than check variety, Kaohsiung 9. KA95-07-257 line of B group had the highest seed yield among 18 tested lines in the fall crop season of 2011, which was 44.5% higher than check, 5) In the first-year lines regional trails, 10 were conducted at 2 locations during the fall crop season of 2011 At 3 locations of Kao-Ping , KA94-03-1、KA94-05-4 lines had the higher seed yield among 10 tested lines, which were 21.0﹪、12.6% higher than check variety, Kaohsiung 9.
