Inbred line production and maintenance
WebAn inbred is a plant that possesses only the traits of the self-pollinated plant. Developing inbreds, the parents of hybrids, which exhibit desirable characteristics, is the researcher’s first step of field breeding. Proper selection of inbreds for parent lines is critical to developing consistent, top-performing products. WebSep 18, 2024 · Testing inbred lines for their combining ability is, due to high numbers of line to line testing needed for determination of hybrid performance, the most limiting factor in the F1 hybrid breeding procedure. We propose a novel method of F1 hybrid breeding that enables evaluation of large number of line to line crosses for their hybrid performance. …
