Screening of High-Yield and Disease-Resistant Asparagus Varieties Suitable for Shanxi Province
摘要
Abstract
The introduction and screening of high yield,high quality and disease resistant asparagus varieties suitable for the climatic conditions of Shanxi Province can better promote the development of the asparagus in-dustry.This study conducted a comparative experiment using Feicuimingzhu,Jinlunsun No.1,Grande and JVS-31-001 asparagus varieties and 3 new asparagus combinations from College from Horticulture,Shanxi Agriculture University as experimental materials,and with the Guanjun serving as the control,which is a high yield and high quality asparagus variety with a large planting area in China.The field cultivation conditions were utilized to evaluate morphological index,yield,quality and disease resistance of the asparagus varieties.A comprehen-sive evaluation was performed through variance analysis(ANOVA),correlation analysis and principal component analysis(PCA)to assess the overall characteristics and production performance of different varieties.The results indicated that all of the asparagus varieties tested could complete normal growth and development and enter the spore picking stage.There were significant differences in plant height,number of stems per plant and stem di-ameter,and the growth index was significantly higher than CK except for JVS-31-001.The spear number(ex-cept for Grande in 2025),spear weight and yield in 2 years were all higher than CK,of which the spear number of all varieties were significantly higher than CK except for JVS-31-001 in 2024 and Grande in 2025,the spear weight in all varieties were signifi-cantly higher than CK except for GJ153 and JVS-31-001,and the yield in 2 years in all varieties were signifi-cantly higher than CK except for JVS-31-001 in 2024 and Grande in 2025.Especially,there was no significant difference among Feicuimingzhu,Jinlunsun No.1,Grande and JVS-31-001,and the yield of the 4 varieties were all significantly higher than other varieties.The first-level spear rate of all the varieties was higher than 90％and all higher than CK,except for JVS,and the first-level spear rate of Feicuimingzhu,Jinlunsun No.1,Grande and JVS-31-001 were higher than other in different years.The incidence of stem blight was significantly less than CK,and the order of disease resistance was JLS＞GF73＞GJ77＞GJ153＞Feicuimingzhu＞Grande＞JVS-31-001.And there was significant difference between all the 6 varieties,except for Feicuimingzhu and GJ153.Correlation analysis showed that yield was positively correlated with growth index,spear number and stem weight significantly or extremely significantly.The principal component analysis showed that the nine measured indexes could be reduced to three principal components(the cumulative contribution rate was 83.88％),among which GF73,Feicuimingzhu and Jin-lunsun No.1 had higher comprehensive scores than other varieties.In summary,GF73,Feicuimingzhu and Jinlun-sun No.1 can be promoted in Shanxi Province for the superior comprehensive performance in terms of agronomic traits,yield and disease resistance.关键词
