Great achievements have been reached in ornamental lily breeding, however, there is little work on edible lily breeding. In order to breed edible lilies as good as ornamental ones, in the present study, two edible lilies, Lilium brownii var. viridulum and L. davidii var. unicolor, were mainly investigated for their microsporogenesis, hybridization, genomic differences, and hybrid identity and fertility using conventional and modern cytogenetic techniques. The results showed that both L. brownii var. viridulum and L. davidii var. unicolor had normal meiosis and fertility; their hybrids could be obtained through cut style pollination and embryo rescue only when L. brownii var. viridulum was used as female and L. davidii var. unicolor as male; the hybrids were male sterile and the two genomes of their hybrids could be distinguished with genomic in situ hybridization. The results are similar to what observed in ornamental LA, OA, OT, and LO lily hybrids. It is concluded that L. brownii var. viridulum and L. davidii var. unicolor are distantly related and the hybrids are promise to breed allotriploid edible lilies in the next few years.

在观赏百合育种方面已经取得了巨大的成就，但是可食用百合育种工作很少。为了繁殖可食用百合和观赏百合一样好的花色，在本研究中，使用了两个可食用百合，即棕百合。viridulum和L. davidii var。使用常规和现代细胞遗传学技术，主要研究了单色的微孢子发生，杂交，基因组差异以及杂种身份和繁殖力。结果表明，两个L. brownii var。viridulum和L. davidii var。单色的减数分裂和生育能力正常；它们的杂种只有在布朗氏乳杆菌变种时才能通过切花授粉和抢救胚胎获得。viridulum用作雌性，L。davidii var。单色如男性; 这些杂种是雄性不育的，可以通过基因组原位杂交来区分它们的两个基因组。结果类似于在观赏LA，OA，OT和LO百合杂交种中观察到的结果。得出结论，布朗氏乳杆菌变种。viridulum和L. davidii var。单色关系很远，杂种有望在未来几年内繁殖出同种三倍体可食用百合。
