Abstract:
【Objective】 Its line for fresh and raisins, this project aims to select high yield and good quality in the hope of providing the foundation for the grape's cultivation with high quality and high yield.
【Methods】 18 diverse lines of this variety were taken as materials, Thompson seedless grape was used as control, the characters of bunch were described, the fruit quality was determined and drying test was carried out.
【Results】 Bunch weight of long-bunch Thompson seedless and Ningxia Thompson seedless were 620.20 and 632.67 g respectively, which were 2.25 times and 2.29 times compared with CK. Berry weight of W
3 was maximum and 3.10 g, followed by big-berry Thompson seedless and berry weight was 2.45 g, which was 2.35 times and 2.97 times respectively. The soluble solid content of 18 lines was lower than that of CK, the reducing sugar contents of big-berry Thompson seedless, W
5 and W
9 were 1.34%, 1.91% and 3.17% higher than that of CK respectively, the sugar-acid ratio of W
5, Zaowuhebai and Hongxiu were significantly higher than that of CK, and increased by 18.11%, 23.34% and 22.97%, VC of big-berry Thompson seedless and W
3 were significantly higher than that of CK, and increased by 6.65% and 3.98. In terms of drying characteristics, dry rate of big-berry Thompson seedless and W
8 were 6.65% and 3.98% higher than that of CK. In addition, shape index of long-berry Thompson seedless raisins was 3.10 and 1.46 times compared with CK, and popular in the market. Zaowuhebai was pink and raisins had unique appearance with yellow-red-reddish-brown color.
【Conclusion】 Long-bunch Thompson seedless, big-berry Thompson seedless and long-berry Thompson seedless have excellent performance, which, in addition, Zaowuhebai can be used as a characteristic strain.
