小米品種(系)選育

Abstract

94 年春作小米新品系比較試驗中以TTS-8501、TTS-8502、TTS-8505 等三個品系採收率可達到79.45~95.56%，其中以TTS-8502 小米仔粒產量最高，達到2,771 公斤/公頃，穗長平均24.5 公分，粒重14.5 公克，脫粒率達到81.77%。 94 年春作小米新品系高級品系試驗經調查結果：以TTS-8305 的採收率最高，達到40.83%，其平均粒重9.60 公克，脫粒率是61.92%，小米仔粒產量才達到980 公斤/公頃。94 年春作小米單穗選拔中以TS2×TTY-504 組合的TTS-8807 單株粒重平均為23.3 公克，脫粒率77.0%；其次是TS2×TTY-500 組合的TTS-8817 單株平均粒重為21.9 公克，脫粒率高達81.7%。 The results of the breeding program were summarized as following : (1). In the preliminary yield trial, The line, TTS-8502 was the highest grain yield - 2,771 kg/ha and 24.5cm of panicle length, the seed extraction rate 81.77%. ( 2). In the advance yield trial in 2005 spring crop, TTS-8305 had the highest recovery ratio - 40.83%, the average grain weight - 9.6g, the seed extraction rate - 61.92%, and the grain yield - 980kg/ha. (3). In the single panicle selection, the combination of TS2×TTY-500 had heavier grain yield per plant - 23.3g, the seed extraction rate - 77.0%, The next one is TTS-8817. It had average grain yield - 21.9 g/plant and 81.7% seed extraction rate.
