低温敏核不育系培矮６４ Ｓ、 Ｌ Ｓ２ Ｓ 在１９ ～２２ ℃井水串灌〈淹没生长点〉条件下自交结实率分别达３５ ．５ ％ 和３７ ．０ ％ 。串联时期为第二次枝梗分化期和减数分裂期，历经１５ 天。以井水为“冷源”串灌繁种技术的实验成功，为北方利用低温敏核不育系，配制两系杂交水稻创造了条件。
The low temperature-sensitive genic male sterile line Peiai 64 S and L S2 S achieved self-fertility of 35% under the conditions of 19-22 ℃ well stringing under flooded growth point. 5% and 37. 0%. The tandem stage was the second branch and the meiosis stage, after 15 days. Well-water as a “cold source” of the success of string breeding techniques for the northern use of low-temperature-sensitive genic male sterile lines, preparation of two-line hybrid rice to create the conditions.
