小米品種(系)選育

Abstract

99 年於臺東市、金鋒鄉及海端鄉的春作區域試驗結果，三試區平均產量以臺東8 號 (CK)的2,084 公頃/公斤為最高，然除豐里試區，在金鋒與海端兩處皆以TTS-8309 的產量表現為最佳，分別較對照品種臺東8 號 (CK) 增產14%與4%；99 年秋作在本場小米區域試驗結果以TTS-8322 籽粒單位面積產量1,443 公頃/公斤為最高，較對照品種臺東8 號 (CK) 1,360 公頃/公斤增產約6%。本場秋作小米新品系區域試驗之海端試區因接連颱風，已終止該田區之試驗。其餘試區則較去年同期作減產約47~60%不等，其中以對照品種臺東8 號減產59.88%最多、以TTS-8322 減產47.06%為最少。99 年小米春作高級試驗結果以對照品種臺東8 號 (CK) 單位面積籽粒產量最高，為3,065 公斤/公頃；秋作以單位面積籽粒產量以TTS-8803 最高，為1,254公斤/公頃，較對照品種臺東8 號之1,031 公斤/公頃增產約22%。 The accession with the highest average grain yield among all 3 experimental field-- Taitung city (at Feng-li station), Chinfong county and Haiduan county, in spring crop of 2010 was Taitung no.8 (control), which is 2,084 kg/ha in average of regional trial. However, except for Feng-li, the accession with the highest yield in both Chinfong county and Haiduan county was TTS-8309, with the performance about 14% and 4 % higher than Taitung no.8 (control) respectively. In autumn crop, TTS-8322 was the accession with the highest average yield, with the performance of 1,443 kg/ha, which was about 6 % higher than Taitung no.8 (control). The experimental field at Haiduan county in 2010 autumn crop was terminated due to the successive typhoons. The yield of other experimental fields also reduced greatly from 47% to 60%. There was 59.88% decrease in yield of Taitung no.8 (control), which was the one with the most decreased yield among all the accessions tested, whereas 47.06% yield reduction of TTS-8322 was the mildest decrease. The accession with the highest average yield of the advance yield trial in 2010 spring crop was Taitung no.8 (control), which was 3,065 kg/ha in average. The accession with the highest average yield of the advance yield trial in 2010 autumn crop was TTS-8803, with the performance of 1,254 kg/ha, which was about 22% higher than Taitung no.8 (control), whose average yield was 1,031 kg/ha.
