Abstract

Hongshuo 729 is a new first-generation hybrid of middle-early maturing tomato variety, which is prepared with inbred line 1863 as the female parent and inbred line 1529 as the male parent. In open fields cultivation, its growing period is about 96 d from sowing to first harvest. It is infinite growth type and strong plant growth potential. The first inflorescence emerged at the 6th to 7th node of the main stem, with 1 inflorescence every about 4 leaves. The mature fruits are oblate and pink with no green shoulder, smooth fruit surface and small fruit umbilicus. Average single fruit mass is 202 g. The content of soluble solids is 5.25%, The vitamin C content is 250.00 mg·kg ^-1 and lycopene content is 22.90 mg·kg^-1. The average yield per 667 m² is about 6 499.8 kg in open field cultivation. It is medium resistant to cucumber mosaic virus (CMV), tomato mosaic virus (ToMV), tomato yellow leaf curl virus (TYLCV), blight, leaf mold and root-knot nematodes. Therefore, it is suitable for planting in the early spring protected area, open field, late autumn protected area and overwintering solar greenhouse in Gansu, Inner Mongolia, Shandong, Ningxia, Qinghai, Yunnan and other regions.
