| 摘要: |
| 以5个樱桃番茄自交系为材料,按Griffing完全双列杂交第一种设计方法,对其7个品质性状的配合力和遗传效应进行了研究。结果表明,各性状的一般配合力方差和特殊配合力方差均达到了显著或极显著水平;可溶性总糖、可滴定酸、糖酸比、维生素C、番茄红素、可溶性固形物等性状主要受基因的加性效应控制,β-胡萝卜素由非加性基因控制;番茄红素的广义和狭义遗传力最高,分别为84.23%和67.76%;Q03是选配高品质组合的理想亲本,Q01×Q03是品质较好的组合。 |

| Abstract: |
| Combining ability and genetic effects of 7 quality characteristics in cherry tomato were analysed by way of Griffing complete diallel crosses design with 5 inbred lines as subjects.The results showed that general combining ability and special combining ability were significantly different.Soluble solid,total soluble sugar,titrationable acid,sugar acid ratio,vitamin C and lycopene were controlled by additive gene effects,and β-carotene was controlled by non-additive gene effects.The broad and narrow heredity of lycopene reached the highest,84.23% and 67.76%,respectively,however,the other traits showed lower heredity.Line Q03 was very useful line for quality breeding.Q01×Q03 could have a good developmental prospect in cherry tomate culture. |
