Abstract

Abstract: A fast generation cycling system (FGCS) was developed in oat and triticale, allowing the production of pure line populations of the crops within 1‐year timeframe. Twelve oat and 12 triticale cultivars were tested using the FGCS, and most of them completed a generation cycle within 48–61 days under the system achieving up to seven generations a year. This system involves growing plants under stressed conditions to promote reproduction and in vitro culture of immature embryos bypassing full seed maturation. The developed system could be widely adopted in breeding and genetic studies of crops for producing desired segregating pure line populations, which could significantly shorten the breeding cycles.
