摘要
Ovule rescue was used to obtain the intergeneric hybrid Chrysanthemum indicum L. Des Moul. x Opisthopappus taihangensis (Ling) Shih. The hybridity of the seven independent progeny was confirmed by morphology, chromosome counting and GISH analysis. Plant height, crown width, leaf length, leaf width, epidermal hair height and epidermal hair length of the hybrid were all intermediate between those of the parents. However, their petiole length and epidermal hair density exceeded those of either parent. GISH analysis of the hybrid was able to distinguish between the parental genomes.
