Odd-allotetraploid lily ‘Honesty’ (LAAA) is a new type of allotetraploid. It would be valuable for lily breeding to analyze its meiosis and fertility. In this study, the odd-allotetraploid lily was investigated for its meiosis and fertility using conventional method, and its progenies were analyzed with genomic in situ hybridization. The results showed that many stages of its microsporogenesis seemed to be normal but some chromosomes were lagged at telophase II and tetrad; only about 6.3% of its pollen grains germinated, much lower than that of diploid or tetraploid Asiatic lilies; Regardless of its high male sterility, it could be hybridized with diploid and tetraploid Asiatic lilies, however, it was much more compatible with tetraploid than with diploid Asiatic lilies; their progenies were usually aneuploid. The results are similar to those reported in allotriploid lilies. Triploid is usually regarded as bottleneck for introgression breeding in polygonum-type crops; nevertheless, Lilium are Fritillaria-type plants, allotriploid or odd-allotetraploid could be good source for lily introgression breeding.
