摘要

水稻新品種桃園4號原品系代號為桃園育42211號，係本場於1995年第二期作以千代錦與新竹64號進行雜交，再進行分離世代選拔、觀察試驗、各級產量比較試驗、區域試驗、各項特性檢定及儲藏試驗，2005年第一期作提出命名登記為桃園4號，其特性為早熟、產量高而穩定、米飯食味及外觀優良、脫粒性適中、穗上發芽率稍低、耐倒伏且抗稻熱病。產量與對照品種臺稉11號相近，區域試驗結果第一期作平均產量7,600 kg ha^(-1)，第二期作平均產量5,361 kg ha^(-1)，穩定性與生產潛力均佳，適合各地區栽培。

The rice new cultivar Taoyuan No.4, originally referred to line Taoyuan Yu 42211 selected from progenies of Chionishiki × Hsinchu 64, was developed and released by Taoyuan District Agricultural Research and Extension Station in the first crop of 2005. Taoyuan No.4 possesses characters of early maturity, lower preharvest sprouting and shattering, resistance to blast disease, high yield potential, good grain appearance, and high eating quality. The average grain yield from the regional yield trials was 7,600 kg ha^(-1) for the first crop and 5,361 kg ha^(-1) for the second crop The regional yield trials also showed that the stability and yield potential of Taoyuan No. 4 were better than the check variety Taikeng No.11. The palatability of cooked rice of Taoyuan No.4 was similar to that of Taikeng No.9. New cultivar Taoyuan No.4 is recommended for growing both in the first and second crop as high-quality rice variety.
