Ploidy and productivity of yeast strains and hybrids obtained by crossing various industrial races were studied. Biological productivity of yeast cultures increases with ploidy as was found by comparing biological productivity (biomass accumulation) in haploids, diploids, triploids, and tetraploids. Possible factors causing an insignificant decrease in productivity of some tetraploids as compared to triploids are discussed.
研究了通过杂交各种工业菌株获得的酵母菌株及杂种的倍性和生产力。通过比较单倍体、二倍体、三倍体和四倍体的生物生产力（生物量积累）发现，酵母培养物的生物生产力随倍性增加。文中讨论了与三倍体相比，某些四倍体生产力显著下降的可能原因。
