摘要
三系不育系亲本1356A(属陕2A血缘)和3A(属波里玛血缘),在思南气候条件下分别于1月上、中旬和1月下旬播种,群体发育整齐,能在4月中旬至5月中旬开花,5月底至6月初成熟,亩产杂种近5O公斤,杂种恢复株率达90～99％。其相应恢复系的播期:1356R第1期比1356A迟10天,第2期比1356A迟20天;80133第1期比1356A迟15天,比3A迟10天,第2期比1356A迟30天,比3A迟20天。
When the 1356A cms (being of consanguinity) and 3A cms (being of Bolima consanguinity) were sown separately from January 1 to 30,the colonial development of plants showed normal, flowered in April 11 to May 20, matured in May end to June first, hybrid yield reached 50kg/mu and its restoring percentage of the hybrid reached 90-99%. The proper sowing date for the restorers are that: 1356R first period should be delayed 10 days than 1356A, second period to be delayed 20 days than 1356A 80133 first period should be delayed 15 days than 1356A, and delayed 10 days than 3A, second period delayed 30 days than 1356A, and delayed 20 days than 3A.
