我们用夏繁V_(41)不育系进行雌蕊生活力测定试验,观察其开花后一周内每天的受精结实情况,现将试验结果简介如下,供制种、繁殖者参考。一、试验方法(一)剪叶、套袋:选择母本不育系同时抽穗的21个穗,剪去上部1—2张功能叶,消除包颈,使稻穗完全外露,减少授粉障碍。为了防止串花,将剪叶稻穗用玻璃纸袋罩住。(二)整穗:将穗顶部已开花或正在开花的和基部因割叶而外露的颖花剪去,尽量使保留的颖花在发育进度上较为一致。(三)授粉:每日取套袋的稻穗3穗,选用开花正盛而一致的V_(41)保持系进行授粉后继续套袋,连续7天,结束一个重复。(四)考种:将不同授粉日期的稻穗单独收获,进 We use Xia Fan V_ (41) sterile line pistil activity test to observe the blooming one day after flowering day fertilization and solidification, the test results are summarized below, for the breeding, breeder reference. First, the test method (a) cut the leaves, bagging: Select the male sterile line at the same time heading 21 ears, cut the top 1-2 functional leaves, eliminating the neck, so that rice ears completely exposed to reduce pollination disorders. In order to prevent the string flower, cut the leaf of rice with a cellophane bag. (B) the whole panicle: the top of the spike has been flowering or flowering and the base cut off the leaves of the spirea cut off, as far as possible to keep the spike in the development of a more consistent. (C) pollination: take the bagged panicle 3 spike daily, the selection of flowering Zheng consistent V_ (41) holding line after pollination to continue bagging for 7 days, the end of a repeat. (D) test species: the date of the different pollination of rice harvest alone, into
