水稻产量由品种、种植地点、品种与种植地点互作,但不同品种间适应性、稳定性存在着差异。本文对黑龙江省水稻7个不同水稻生态区,6个水稻品种(系),试验结果表明:适应性较好有B2(绥04—5348)、B4(龙交06—2110)、B1(龙交04-908),好的有B3(盛昌06—0123),B5(牡06—1318)、B6(绥粳11)表现较差;试验品种(系)B4(龙交06—2110)在试验地点C4(鸡西种子管理处)表现最好,产量为9389.2 kg/hm2。
Rice yield varies by species, planting location, variety and planting site, but there are differences in adaptability and stability among different varieties. In this paper, seven different paddy rice ecological regions and six rice cultivars (lines) in Heilongjiang Province were studied. The results showed that the adaptability was better in B2 (Sui 04-5348), B4 (Longjiao 06-2110), B1 04-908), but B3 (Shengchang 06-0123), B5 (MU06-1318) and B6 (Suijing11) performed worse. In the experiment, B4 (Longjiao 06-2110) Location C4 (Jixi Seeds Management Office) performed best with a yield of 9,389.2 kg / hm2.
