我场科技组在水稻杂交育种工作中简化杂交技术,用一根别针或一支大头针、家用剪子,先后育成了吉良红、科珍4号、吉良11、12号等12个良种,本县其它单位采用此法的也育出了红农、红珍等良种。一、杂交方法步骤(一)透视选粒:晴天上午8点钟左右,把正抽穗的稻花对着太阳看,能清晰地见到三种暗影情况(图1):(1)是前一天已授粉的;(2)是今天还不能开花的,都可淘汰剪去;只有(3)方形暗影在上端的,标志着当天将开花,应把它留下。这样一穗只留8—9粒或20—30
My field science and technology group in the hybrid rice breeding work to simplify the hybridization technology, with a pin or a pin, household scissors, has bred Ji Liang Hong, Kezhen No. 4, Ji Liang No. 11, 12 and other 12 varieties, the county other Units using this method also raised red peasants, red and other seeds. First, the hybridization method steps (A) Perspective granule: sunny at about 8 o’clock in the morning, the heading is heading to the sun to see rice, can clearly see the three kinds of shadow situation (Figure 1): (1) the day before Pollination; (2) is not flowering today, can be eliminated cut; only (3) square shadow at the top, marking the day will flowering, it should be left. Such a spike only leave 8-9 tablets or 20-30
