摘要

落花生花蓮1號的父母本分別為ICG（FDRS）-46及台南選9號，於民國76年春作進行人工雜交，民國76年秋作至民國78年秋作以單粒後裔法進行雜交後代分離與培育及選拔單株，民國79年春作至81年秋作進行品系試驗（品系代號為HL76-14），民國83年春作至84年秋作進行區域試驗（品系代號為花育2號），由於產量佳，莢果大小整齊，且不易發生葉部黃化現象，於民國86年10月16日通過審查，登記為「花蓮1號」。落花生花蓮1號屬於西班牙型（Spanish type），生育日數春作約120～130天，秋作約為105～115天。植株直立，株高較矮（春作約40.9 cm，秋作約35.1 cm），不易倒伏，分枝數5～6支。葉綠色橢圓型、莖呈淺綠色、花橙黃色，莢果中筒形，略有腰，具有網紋，長約2.88 cm、莢寬約1.30 cm，每莢通常有二個籽粒。百莢重約147.5～154.5 g，籽粒為橢圓形，長約1.46 cm、寬約0.81 cm，百粒重約60.1～63.1 g，種皮為粉紅色。平均莢果產量春作約3411 kg/ha，秋作約2807 kg/ha；籽粒產量春作約2370 kg/ha，秋作約1934 kg/ha。籽粒油分含量春作約48.2%，秋作約47.8%；蛋白質含量春、秋作均為30.9%。銹病與葉斑病田間調查結果均比對照品種台南選9號具抗病性。

A new peanut variety Hualien No. 1 has been developed and released by Hualien DAIS in 1997. This variety was derived by using the single-seed descent method from a cross between Tainan S.9 and ICG (FDRS)-46 at spring crop in 1987. The final single plant selection was made in F5 generation and Hualien No. 1 was evaluated in series of tests during 1990~1992 at the experimental field of Hualien DAIS, and at the major peanut production area in Hualien under the designation of HL76-14. In addition, Hualien No. 1 was evaluated in regional yield trials around the Island during 1994-1995 for its yield potential and stability under the designation of Hua-Yu No. 2.Hualien No. 1 is Spanish type peanut with erect growth habit and required approximately 120 to 130 days and 105~115 days to harvest, respectively, in the spring and fall environments in Taiwan. It has two-seedes pod with medium cylindrical shape, constriction and reticulation. The pod size is 2.88 cm x 1.30 cm, and the kernel size is 1.46 cm x 0.81 cm. The 100-pod weight is 147.5~154.5 g and the 100-kernel weight is 60.1~63.1 g. Hualien No. 1 possess high yield potential and the average pod yield is 3411 kg/ha in the spring crop and is 2807 kg/ha in the fall crop. The average kernel yield are 2370 and 1934 kg/ha in the spring and fall crop, respectively. Oil and protein content are 47.8~48.2% and 30.9%, respectively. Hualien No. 1 has higher resistance to rust and leaf spot than the commercial cultivar Tainan S.9 and tolerance to leaf chlorosis in the field condition.
