摘要
鄂籼杂１号系用新恢复系０９２－８－８与珍汕９７Ａ配组育成的三系杂交水稻新组合。具有高产、稳产、米质好、耐肥耐寒、抗倒伏、再生能力强、适应性广等优点。１９９３～１９９６年在湖北省已累计示范种植７．４万ｈｍ２，平均单产７．５ｔ／ｈｍ２以上。
Exianza 1, i.e., Zhenshan 97A×092-8-8, is a newly-developed three-line indica hybrid rice combination. It has the characteristics of high and stable yielding ability (in 1994 and 1995 Hubei provincial regional trials, it ranked the first in grain yield with a very significant yield advantage of 12% averagely to the check hybrid rice Shanyou 64; in the demonstration and experimental production with a total area of 74 000 hm 2 in Hubei during 1993～1996, it yielded more than 7.5 t/hm 2 on average with a yield increasing percentage of 12.5%～32.0%), acceptable grain quality (brown, milled and head rice are 82.12 %, 73.19 % and 62.61%, respectively, length: width ratio 2.4, chalky rice 54.5%, amylose and protein contents 20.67% and 8.84%, respectively), good tolerance to coldness, good lodging resistance, strong ratooning ability and wide adaptability. The cultural techniques grown as double cropping late rice as well as main crop plus ratoon rice and seed production techniques were also discussed.
