1968-1978年,通过选用分属不同生态型的亲本品种之间的杂交育种,育成罐藏专用小果型品种扬州24号和扬州红,已在江苏省部分地区推广应用。继从扬州24号群体的变异单株中又初步选出长果3号新株系,适于整形罐藏,兼可制酱,正在进行生产试验中。结合杂交育种工作,同时对果实可溶性固形物,蕃茄红素含量、胶瓤颜色和抗裂果性等有关加工性状遗传,进行了初步的观察和分析。 From 1968 to 1978, Yangzhou No.24 and Yangzhouhong, the small fruit-type cultivars for breeding, were bred by crossbreeding between selected parents of different ecotypes. They were popularized and applied in some areas of Jiangsu Province. Following from the Yangzhou 24 groups of mutant individuals and initially selected the new No. 3 Changoguo, suitable for plastic storage tank, and can be made sauce, ongoing production test. Combining with the breeding work, the inheritance of soluble solids, lycopene content, gum color and anti-cracking fruit properties were also observed and analyzed.
