Abstract
臺農秈20號為本省經雜交育成之秈型香米品種，具有濃芳之香味，米質優良，並抗稻熱病，褐飛蝨等病蟲害，株高一期作109.3公分，二期作115.0公分；每株穗數一期作16.1支，二期作12.4支；全生育日數一期作143天，二期作107天；粒型中長稍細，米粒富光澤，心腹白少，直鏈性澱粉含量18.5％，種子稍具休眠性，稻穀產量根據區域試驗結果，平均每公頃一期作為6,061公斤，二期作為5,371公斤，一期作在高屏地區較高產，二期作在褐飛蝨易發生地區都適合栽培。
本品種耐寒性較差，一期作不宜過早育苗及插秧，以免秧苗受寒害，又本品種較易脫粒，在沿海季節風較大地區避免種植，以免脫粒損失，香米之香味為揮發性，因比貯藏時最好放置通風良好之涼冷地方。
Rice variety Tainung Sen 20 was a selection from the cross between Chianung Shi-pi 671178 and a F4 line, having heavy aromatic flavor, excellent rice quality and resistance to blast disease and brown planthopper. Its plant height was 109─115 cm with panicle number of 12─16 per hill, and the growing duration, 107─143 days. It has long grains somewhat slendel and shinny, with very few white-belly kernel. The average grain yield at 3 locations in 2 years was 6,061 kg/ha and 5,371 kg/ha, respectively in the first and second crops. The yield potential was higher at Kao-ping area in the first crop. It is adaptable in where the brown planthopper prevails.
This variety is less cold tolerance, therefore, it is not recommended for early planting in the first crop. Since this is easy-shatting, it is not recommended to be grown in the coastal region where monsoon is strong and keep this rice in a cool place for storage to maintain the aromatic flavor.
