摘要:
为指导农民选择适宜的水稻品种，以黑龙江省第三积温带24份水稻品种为材料，进行大田对比试验。结果表明：所有参试品种抗稻瘟病较好，有近一半品种有不同程度倒伏发生，有个别品种表现结实率偏低。在农艺性状上，各品种株高差异较大；穗数和每穗粒数上各品种表现为分蘖少大穗型品种，分蘖多穗数型品种，还有二者兼顾型品种；其它性状变化较小。产量高于平均值的品种有11个，整精米率超过70%的品种有14个。选择品种时首先要考虑品种的适应性和抗逆性，其次是要产量和出米率兼顾。适当增加株高，调控穗数，增加粒数，提高品种抗逆性为主要育种目标。
Abstract:
In order to guide farmers to choose the suitable rice varieties,taking 24 rice varierties of third accumulated temperature zone in Heilongjiang province as materials for comparative test.The results showed that all varieties of rice blast resistance were better,nearly half of the species had different degree of lodging, some varieties showed lower seed setting rate.In agronomic traits, the plant height was different.All varieties of panicles showed fewer tillers large panicle varieties, more tillers and panicle type varieties, considering two varieties; other characters had small change.The yield was higher than the average of the 11 varieties, the whole milled rice rate of more than 70% varieties of 14 varieties.Selection of varieties should be considered when varieties of resistance and adaptability, the second yield and whole milled rice rate should be both considered.Appropriate increase plant height, spike number, grain number increased regulation, and improve the resistance of varieties were the main breeding direction.
