| 摘 要： | 为了明确作物品种(系)间的耐冷性,在孕穗期采用深冷水串灌的方法对黑龙江省第二积温带的部分水稻品种(系)进行耐冷性筛选和鉴定。结果表明:绥12-7101、龙粳21、绥粳14、绥粳4号耐冷性表现极强,另外还筛选出11个耐冷性较强的品种(系),其中绥12-7101的耐冷性表现最好,而6035、绥12-008、绥12-082、龙粳30、绥12-079、绥12-027、绥12-029、绥12-020和绥12-015的耐冷性表现稍差一些。

| Abstract: | In order to determine cold tolerance of rice varieties（lines）,the cold tolerance of rice varieties（lines）in the second accumulated temperature zone of Heilongjiang province was identified.Using cold water irrigation under natural conditions at jointing-booting stage,the rice varieties by contrasting the data of cold resistance were screened.The results showed that rice varieties with stronger cold tolerance was Sui 12-7101,Longjing21,Suijing 14,Suijing 4,and Sui 12-7101 which was the best,also screened 11 varieties performing not worse.The rice varieties whose cold tolerance perform slightly worse including 6035,Sui 12-008,Sui 12-082,Longjing30,Sui 12-079,Sui 12-027,Sui 12-029,Sui 12-020,Sui 12-015. |
