1979年,上海市农科院植保所,参加国际水稻抗褐稻虱试验圃(IRBPHN),筛选出两份抗褐稻虱的粳稻品种,即79—29(KANTO PL_2)和80—101(78F_4 202)。经过南繁,于1981年在丹阳县良种场进行试种,现将初步结果简报如下。 (一)生育特性:80—101 5月27日播种,至始穗天数为84天,全生育期125天左右,属于早熟中粳类型。79—29同期播种至始穗天数为95天,比筑紫晴早5天左右抽穗,全生育期140天左右,属中
In 1979, the plant protection institute of Shanghai Academy of Agricultural Sciences participated in the International Rice Brown Planthopper Test (IRBPHN), and screened two japonica rice varieties resistant to brown planthopper, namely, 79-29 (KANTO PL_2) and 80-101 (78F_4 202). After the South Fan, in 1981 in Danyang County seed field trial planting, the preliminary results are summarized below. (A) of fertility characteristics: 80-101 May 27 sowing, to the ear number of days is 84 days, the whole growth period of about 125 days, belong to the early maturing japonica type. 79-29 Sowing to the beginning of the same day the number of days for the first 95 days, five days earlier than purple clear heading purple heading, the whole growth period of about 140 days, is
