    摘要:

    2021—2023年河南省项目组在“第三次全国农作物种质资源普查与收集行动”中,对省内128个县(市、区)开展农作物种质资源的全面普查和征集工作。经过系统调查共普查到1956年、1981年和2014年水稻种植县信息累计120条;征收集到水稻种质资源37份,并对其中33份的田间性状进行了调查鉴定。普查数据显示,河南省水稻呈现出种植区域集中,种植面积增加,地方品种急剧减少的特征。征收集到的水稻种质资源主要分布在豫北稻区和豫南稻区,大部分分布在海拔50~100m范围。河南省水稻种质资源中,粳稻多于籼稻,粘稻多于糯稻,香稻和有色稻分别占总资源数的27.27 %和21.21 %。资源表型变异丰富,多样性程度高,多表现为株高中等偏高,茎秆直立且较长,穗长穗型适宜,穗抽出良好,成熟后呈弯曲状,穗部二次枝梗多分枝,叶鞘色和叶色绿色,叶舌二裂,剑叶宽度适中,剑叶和倒二叶为直立型,籽粒无芒,外颖黄色且有毛。综合表型性状筛选出息县香稻丸1号、三粒寸、菡香一号F11、毛铺软稻、黑香糯、绿米等6份优异水稻种质资源。本研究可为河南省水稻种质资源的有效保护和利用提供科学依据。

    Abstract:

    From 2021 to 2023, the Henan team of the “Third National Crop Germplasm Resources Census and Collection Action” carried out a comprehensive survey and collection of crop germplasm resources in 128 counties/cities in the Henan province, P.R. China. A total of 120 rice planting information in 1956, 1981, 2014 was obtained. The census data showed that in Henan Province, the rice planting area was concentrated, the planting area increased, and the landraces decreased sharply. At the same time, a total of 37 rice germplasm resources were collected, and the field traits of 33 rice germplasm resources were investigated and identified. The collected rice germplasm resources were mainly from the northern and southern Henan rice areas. 63.64 % of them were planted at an altitude of 50-100 m. Phenotypic character identification showed that japonica rice was more than indica rice, lowland rice was more than upland rice, nonglutinous rice was more than glutinous rice, fragrant rice and colored rice accounted for 27.27 % and 21.21 % of the total resources, respectively. The phenotypic traits of resources were rich in diversity. Most germplasms showed the characters such as high plant height, erect and long culm, suitable panicle length and panicle type, good panicle extraction, curved shape after maturity, multiple branches of secondary branches in panicle, green leaf sheath color and leaf blade color, double-lobed ligule shape, moderate width of flag leaf, erect flag leaf and second leaf, awnless grain, yellow and hairy glume. Based on the phenotype,six excellent rice germplasm resources were screened out , including Xixianxiangdaowan No.1, Sanlicun, Hanxiang No.1 F11, Maopuruandao, Heixiangnuo, Lvmi. In conclusion, this study would provide a scientific basis for the effective protection and utilization of Henan rice germplasm resources.
