摘要
浙江省作为我国经济较为发达的地区,较早地开展了水稻新品种选育研究。浙江省种植的品种基本涵盖了各种水稻类型,其中粳稻是主要的种植类型,尤其是晚粳稻。虽然自杂交水稻出现后,常规水稻面积占比日益减小,但由于晚粳稻兼顾产量和品质,在生产上仍具有不可替代的地位。对晚粳稻产量影响最大的4个因素进行分析,发现可以通过增加穗粒数和有效穗数以及千粒重来提高产量。除了产量的提高之外,稻米品质也成为了晚粳稻育种的主要目标,因此,现在的育种工作已经将米质作为重要育种目标。本文主要通过对浙江省近20 a通过审定的晚粳稻品种进行生育期、产量、品质、抗病性等方面的分析,总结浙江省粳稻品种的性状变化,以期为浙江省的粳稻育种工作提供参考依据。
The research on the breeding of new rice varieties was carried out earlier in Zhejiang Province,a relatively economically developed region in China.The varieties planted in Zhejiang Province basically include various rice types,among which japonica rice is the main planting type,especially late japonica rice.Although the proportion of conventional rice area has been decreasing since the emergence of hybrid rice,it still has an irreplaceable position in production due to the balance between yield and quality of late japonica rice.Based on the analysis of the four factors that had the greatest impact on the yield of late japonica rice,it was found that the yield could be improved by increasing the number of grains per spike,the number of effective panicles and the 1000-grain weight.In addition to the improvement of yield,rice quality has also become the main goal of late japonica rice breeding,so rice quality has been regarded as an important breeding goal in the current breeding work.In this paper,we analyzed the growth period,yield,quality and disease resistance of late japonica rice varieties approved in Zhejiang Province in the past 20 years,and summarized the changes of traits of japonica rice varieties in Zhejiang Province,in order to provide a reference for the breeding work in Zhejiang Province.
