Abstract：To screen suitable rootstock varieties for the grafting cultivation of fresh tomato in Ningxia solar greenhouse,the fresh tomato variety Jingcai No.6 was used as the scion.The effects of nine tomato rootstocks on the growth,yield,and quality of fresh tomato grafted plants were studied at different crop lengths in the solar greenhouse,and a comprehen-sive evaluation was conducted.The results showed that compared with CK,all nine rootstock varieties significantly in-creased the height and growth rate of grafted tomato plants,promoted the increase of leaf nodes and some rootstocks could also increase the growth rate of stem diameter in both spring and autumn cultivation in the solar greenhouse.The in-cidence of viral diseases in plants grafted with 5 rootstocks in spring and 9 rootstocks in autumn significantly decreased.Different rootstocks increased the average yield of fresh tomato in spring and autumn by 24.85％and 52.56％,respective-ly,with varying increases among different rootstock varieties.Compared with CK,partial rootstock grafting reduced the soluble solids content of the fruit,but increased the soluble sugar content and sugar acid ratio.By using flavor indicators,commodity indicators,growth indicators,and nutritional indicators for analytical hierarchy process(AHP)and weight-ing,the DTOPSIS method was used to calculate the ranking,it was found that Huizhen No.1 ZZ1 and Oubei Tomato OB ranked among the top three in spring and autumn cultivation.The grafted plants showed excellent growth,resistance,yield,and quality,and can be used as reference rootstocks for fresh tomato in solar greenhouse in Ningxia.
