| 摘 要： | 目的]对江苏省杂交中粳与常规中熟中粳水稻主要性状进行比较分析。方法]利用2013—2016年江苏省杂交中粳和常规中粳区域试验数据,对新选育的杂交中粳与常规中熟中粳品种的主要农艺及品质性状进行比较分析。结果]与中熟中粳相比,杂交中粳组合表现为植株高大、穗大粒多,但穗数较少、结实率偏低;主要品质性状表现为整体水平低于常规中熟中粳品种,但在整精米率和粒型上具有一定的优势。结论]该研究为杂交粳稻育种的改良及推广提供参考。

| Abstract: | Objective] To compare and analyze the main characters between medium hybrid japonica rice and medium maturing medium japonica rice in Jiangsu Province.Method] The regional trial data of medium hybrid japonica rice and medium maturing medium japonica rice in Jiangsu Province in 2013-2016 were used to compare and analyze the main agronomic and quality characters of newly breed medium hybrid japonica rice and medium maturing medium japonica rice.Result] Compared with medium maturing medium japonica rice,medium hybrid japonica rice had higher plant,bigger and more grains,but less ear number and relatively low seed-setting rate.The main qualitative characters of medium hybrid japonica rice were generally lower than that of the medium maturing medium japonica rice,but had certain advantages in head rice rate and grain shape.Conclusion] This research provides references for the improvement and extension of hybrid rice breeding. |
