简介
Background
In-vivo maternal haploids serve as the basis of doubled haploid (DH) breeding in maize. R1-navajo (R1-nj) gene governing anthocyanin colouration in the endosperm and embryo is widely used to identify haploid seeds. However, the expression of R1-nj depends on genetic-background of source-germplasm used for deriving DH-lines. Further, presence of C1-Inhibitor (C1-I) gene suppresses the expression of R1-nj, thus makes the selection of haploids difficult.
Methods
In the present study, 178 subtropically-adapted maize inbreds were crossed with two R1-nj donors ‘that do not have haploid induction genes’. Of these, 76.4% inbreds developed purple colour in endosperm, while 23.6% did not show any colouration. In case of scutellum, 62.9% inbreds possessed colour and 37.1% were colourless. The anthocyanin intensity varied greatly, with 19.66% and 42.98% inbreds displayed the least intensity …
