长龄,是我所近年来选育成功的含有纯合nor基因的耐贮番茄品种。nor基因除了影响果实的耐贮性状外,对果实硬度、色素组成及品质风味均有不同程度的影响。为了更好地推广利用长龄番茄,1989～1990年开展了对其耐贮性及品质性状的分析研究。 材料与方法 试验以含纯合nor基因的耐贮番茄长龄及其亲本双黄5号(♀)、84-139(♂)和苏抗5号(CK)为材料。于1989年7月、1990年7月,将采收后各品种番茄分成白熟果、转色果及半红果3种类型,用0.3％强氯精浸
Long age, is a variety of storable tomato that contains homozygous nor gene that I have successfully bred in recent years. In addition to the nor genes that affect the storability of fruits, the nor genes have different degrees of impact on fruit firmness, pigment composition and quality and flavor. In order to promote the use of long-term tomato, from 1989 to 1990 to carry out the analysis of its storage resistance and quality traits. MATERIALS AND METHODS Experiments were conducted on long-staged resistant tomato parents and their parents Shuanghuang 5 (♀), 84-139 (♂) and Sukang 5 (CK) with homozygous nor gene. In July 1989, July 1990, after the harvest of all varieties of tomato is divided into white ripe fruit, turn the color fruit and half red fruit three types, with 0.3%
