Embodiment 1
[0083] Example 1. Breeding and application of an induction line for efficient identification of maize haploid immature embryos
[0084] 1. Breeding of induction lines for efficient identification of maize haploid immature embryos
[0085] Schematic diagram of breeding induced lines for efficient identification of maize haploid immature embryos image 3 .
[0086] 1. In the spring of 2015, the maize haploid induction line (CAU3 or CAU5) was used as the male parent and S23 was used as the female parent to obtain hybrid F1.
[0087] The hybridization method is: field planting (experimental site is Beijing) maize haploid induction line (as the male parent) and S23 (as the female parent), and before the filaments of the female parent are spit out, they are subjected to emasculation and ear bagging; After the filaments are spit out, cut the filaments and pollinate.
[0088] 2. In the winter of 2015, hybrid F1 was planted in the field (the experimental site was Hainan), and backcr...
