To screen the rootstock resources for superior traits of convergent parents，94 individual plants of F₁ hybrid population with Red tangerine as the female parent and Trifoliate orange as the male parent were used as test materials to observe their defoliation period and flowering period for two consecutive years，and the fruit quality，seed embryo types and germination rate of 37 individual plants with high fruition rates were analyzed. The results showed that the phenology of 94 individual plants was similar to that of their parents，but there was a significant difference in the defoliation period between hybrid progenies. The fruit shape of the hybrid population was more inclined toward paternal inheritance，mainly oval in shape. The average fruit weight of the offspring populations was 58.63 g，average number of seeds was 14，and 1000-grain weight was 153.73 g.The soluble solid content was 10.7%?16.5%，which was not significantly different from that of the female parent，and the titratable acid content of fruit was 2.00%?5.56%，which was significantly higher than that of the female parent. The flavedo of the hybrid population mainly includes red peel （female parent preferred） and yellow peel （male parent preferred）. The contents of β-cryptoxanthin were significantly higher than those of the parents，and the contents of violaxanthin lutein and zeaxanthin were between those of parents，while the contents of β-carotene in the peel of parents and hybrid offspring were relatively low. The contents of violaxanthin，lutein and β-carotene showed continuous changes，which showed quantitative characteristics. The ratio of monoembryoid to polyembryoid types in the hybrid progeny was close to 1∶3，which indicated that the character was determined by a single gene. In summary，the results showed that the progeny No. 3，No. 6 and No. 24 had the characteristics of polyembryony ，more seeds per fruit and a high germination rate，and could be used as excellent rootstock candidates for further evaluation.
