摘要： 对耐贮番茄Lok、自交系97-114、大黄柿子、桔黄佳辰、樱桃黄、小黄梨和醋栗番茄分8个生育阶段取样,进行过氧化物酶同工酶酶谱分析,探讨耐贮番茄的亲缘关系和来源.结果表明,耐贮番茄Lok是普通栽培品系97-114的突变体,而与野生亚种的亲缘关系较远.另外,耐贮番茄Lok随生育期进展谱带增减发生了变异,从而也映证了Lok发生了基因突变.

Abstract: In order to approach the sibship of the long-keeping tomato lok, a sel-f bred line 97-114, two var-i eties of ssp.cultum Brezh, two varieties of ssp.subspontaneum Brezh, and a var.eupimpinellifolium variety of ssp.Plimpinellifolium Brezh were studied, samplings were taken at different developmentaLstages.It was proved that the long-keeping tomato lok was a mutant of cultivated subspecies and the relationship with wild subspecies was far away.Moreover, at one of 8 developmentaLstages, the zymogram patteras of lok was differ-ent from that of the line 97-114.T his could show the result of gene mutation.
