摘要:

对2001—2018年通过河南省审定的水稻品种基本情况及其产量、米质等性状进行了介绍分析。结果表明,2001—2018年河南省通过审定品种132个,其中籼型水稻77个、占比58.33%,粳型水稻54个、占比40.91%,籼粳杂交稻1个、占比0.76%;育种单位涉及科研、教学及推广单位、种业企业等,种业企业选育或参与选育的品种比例正逐渐增加;审定品种年度间产量总体呈上升趋势,并以粳型杂交稻和籼型两系杂交稻产量最高;46.21%的水稻品种达到国标优质稻谷等级,粳型水稻优质达标率高于籼型水稻,垩白粒率和垩白度是限制河南稻米品质等级的主要因素,有待进一步提高。

Abstract:

In this study, the author analyzed the characteristics of rice varieties registered by Henan province from 2001 to 2018. 132 rice varieties, including 77 indica rice, 54 japonica rice, 1 indica-japonica hybrid rice; the percentage of rice varieties bred by seed enterprises was rapid increased. The yield analysis showed a significant rising trend, the average yield of japonica hybrid rice and two lines indica hybrid rice were higher than other variety types.
