Abstract
臺農70號係以臺農67號爲母本與嘉農系比662028雜交而育成。本品種具有高產良質及抗多種病蟲害之特性。株高一期作106.1公分，二期作115.8公分比臺農67號稍高；穗數一期作16.7支，二期作14.4支；全生育日數一期作140天，二期作109天；稻榖產量根據全省區域試驗7個地區平均一期作爲6,230公斤，二期作爲5,685公斤，較對照品種臺農67號增產0.1~7.3騙；糙米率一期作82.1%，二期作81.4%。Rice variety Tainung 70 was a selection from the progensis of a cross between Tainung 67 and Chia-nung-sipi 66028, having a high-yield potential, good quality and resistance to major diseases and insect pests. Its average plant height was 106.1cm in the first crop and 115.8cm in the second crop, slightly higher than those of Tainung 67. The panicle number was 16.7 in the first crop and 14.4 in the second crop in average, and the total growing duration was 140 and 109 days in the first and second crop, respectively. The average yield of Tainung 70 in the seven regional yield tests was 6,230kg /ha in the first crop and 5,685kg/ha in the second crop, outyielded the control variety Tainung 67 by 0.1%-7.3%.
