The genomes of the recently discovered yeast Saccharomyces eubayanus and traditional S. cerevisiae are known to be found in the yeast S. pastorianus (syn. S. carlsbergensis), which are essential for brewing. The cryotolerant yeast S. bayanus var. uvarum is of great importance for production of some wines. Based on ascospore viability and meiotic recombination of the control parental markers in hybrids, we have shown that there is no complete interspecies post-zygotic isolation between the yeasts S. eubayanus, S. bayanus var. bayanus and S. bayanus var. uvarum. The genetic data presented indicate that all of the three taxa belong to the same species.
已知最近发现的酵母巴氏酵母（Saccharomyces eubayanus）和传统的酿酒酵母（S. cerevisiae）的基因组存在于酵母卡尔斯伯酵母（S. pastorianus，同义词：S. carlsbergensis）中，这对于酿造至关重要。耐低温酵母葡萄汁巴氏酵母（S. bayanus var. uvarum）对于某些葡萄酒的生产非常重要。基于杂种中对照亲本标记的子囊孢子活力和减数分裂重组，我们已经表明，巴氏酵母、巴氏酵母变种bayanus和葡萄汁巴氏酵母之间不存在完全的种间合子后隔离。所呈现的遗传数据表明，这三个分类单元都属于同一物种。
