樱桃番茄新品种圣亚的选育

Breeding of a new cherry tomato variety, Shengya

摘要: 选择亲缘关系较远且性状差异较明显的9个樱桃番茄高代自交系,配制39个杂交组合。通过比较观察,组合T-013(圣亚)综合性状表现优良,生长力强,中早熟,果实椭圆形且光泽,红色,果肉多,种子少,品质佳,糖度7.8～8.5度,单果重12～15g。参加福州、宁德、三明多点试验,总产量达52000～55000kghm-2,分别比对照品种龙女增产19.3%、20.7%、18.5%。

Abstract: By using 9 high-generation,inbred lines of cherry tomato varieties with distinctively different characteristics among them,39 hybrid combinations were bred for comparison.Among them,the combination T-013(Shengya) showed the most desirable overall characteristics.It grew vigorously,matured in middle-to-early season,and its oval,glossy,red fruits were full-flesh with few seeds,a desirable sweetness of Brix 7.8-8.5,and weighed 12-15g.Field tests on Shengya at various locations rendered a fruit yield ranging from 52000 to 55000 kghm-2,which were 19.3%,20.7% and 18.5% higher than that of the control at Fuzhou,Ningde and Sanming,respectively.
