Interspecific Cross-Breeding Between Iris Domestica and I. Dichotoma

Meiotic behaviour and pollen fertility of F1, F2 and BC1 progenies of Iris dichotoma and I. domestica

“…Its individual flowers stay open for about 4 h in form the late afternoon to the early evening (Luo et al, 2016). To improve its flower colour and flowering time, interspecific crosses were conducted to introgress useful genes from I. domestica to I. dichotoma and this has resulted in some novel varieties (Yang et al, 2013;Lian et al, 2016;Ruan et al, 2017;Xu et al, 2017;Gao et al, 2020). Previous studies concentrated on violet and white-flowered I. dichotoma plants (Chimphamba, 1973;Ruan et al, 2017), whereas I. dichotoma with yellow flowers has not been comprehensively investigated.…”
