一、水稻品种的选育推广情况台湾省在20年代前全部栽培籼稻品种,20年代后由于粳稻品种的培育成功,粳稻面积逐年上升,到40年代占水稻面积的60%以上,目前达94%左右。现将粳籼稻品种的选育推广情况介绍如下: 1.粳稻品种的选育推广情况台湾省粳稻生产在40年代前,由于粳稻品种不抗稻瘟病,发展较慢。1949年台湾省农业试验所嘉义分所第一个育成抗稻瘟病品种光复1号开始,随着抗病品种的选育成功并推广,面积逐渐发展。光复1号新品种推广不久,台中区农业改良场又育成了光复401号新品种,其后,嘉农242号新品种育成并一、水稻品种的选育推广情况台湾省在20年代前全部栽培籼稻品种,20年代后由于粳稻品种的培育成功,粳稻面积逐年上升,到40年代占水稻面积的60%以上,目前达94%左右。现将粳籼稻品种的选育推广情况介绍如下: 1.粳稻品种的选育推广情况台湾省粳稻生产在40年代前,由于粳稻品种不抗稻瘟病,发展较慢。1949年台湾省农业试验所嘉义分所第一个育成抗稻瘟病品种光复1号开始,随着抗病品种的选育成功并推广,面积逐渐发展。光复1号新品种推广不久,台中区农业改良场又育成了光复401号新品种,其后,嘉农242号新品种育成并
I. Popularization and Selection of Rice Varieties Taiwan Province all cultivated indica rice varieties before the 1920s. Since the 20s, due to the successful cultivation of japonica rice varieties, the area of japonica rice increased year by year, accounting for more than 60% of the paddy area in the 1940s, up to 94% about. Breeding and promotion of japonica rice varieties now introduced as follows: 1. Breeding and promotion of japonica rice varieties in Taiwan Province before the 40s of the 40th, because Japonica rice varieties are not resistant to blast, the development is slow. In 1949, the first bred rice variety Guangfu No.1 in Chiayi Branch of Taiwan’s Agricultural Experiment Station began to develop gradually with the successful breeding and promotion of resistant varieties. Soon after the promotion of new varieties of Guangfu No. 1, a new variety of Guangfu No. 401 was bred in Taichung Agricultural Improvement Field. Subsequently, new varieties of Jiaonong No. 242 were bred and popularized. Breeding and Promotion of Rice Varieties Taiwan Province was cultivated before the 1920s Indica rice varieties, after the 20s because of the successful cultivation of japonica rice varieties, the area of japonica rice increased year by year, accounting for more than 60% of the rice area in the 1940s, up to now about 94%.
