Segregation ratios of leaf colour and lethality in golden-leaved Pelargonium x hortorum Bailey

Popis výsledku v původním jazyce

The aim of our study was to test segregation ratios in golden-leaved pelargoniums, particularly from the aspect of the production of golden-leaved hybrid varieties propagated by seeds. The golden colour of leaves in Pelargonium x hortorum is controlled by the nuclear gene aurea with incomplete dominance. Golden-leaved types may exist only as heterozygotes (Aur+/Aur) while the light yellow homozygous constitution (Aur/Aur) is lethal. When heterozygous golden-leaved and homozygous green-leaved ((Aur+/Aur+) lines were crossed, only three golden-leaved lines (from the five tested) had progenies with segregation ratios consistent with expected segregation ratio 1:1. But also in these consistent progenies was, in the most cases, the class of golden-leaved heterozygotes reduced (reduction by 7-8%). Two hybrid combinations had segregation ratios significantly different (reduction of golden-leaved herozygotes by 15% and 43%).
