Collection,Identification and Evaluation of Rice Germplasm Resources in Henan Province,China
摘要
Abstract
From 2021 to 2023,the Office of the Third National Crop Germplasm Resources Census and Collection Action in Henan province 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 were collected,37 rice germplasm resources were collected,and 33 of them were investigated and identified.The rice planting in Henan showed some trends of concentrated planting area,increased planting area and sharp decrease of local varieties.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 that the plant height was between 100.1-120.0 cm,the culm was erect and length was between 80.1-100.0 cm,green leaf sheath color and leaf blade color,double-lobed ligule shape,erect flag leaf and last second leaf,the flag leaf length was 25.1-30.0 cm and 40.1-45.0 cm,the flag leaf width was 1.51-1.75 cm,well exserted panicle extraction,intermediate panicle type,the panicle length was 15.1-30.0 cm,curved shape of panicle after maturity,multiple branches of secondary branches in panicle,awnless grain,yellow and hairy glume.Based on the phenotype,sixexcellent 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.关键词
