WebThe production of a hybrid corn variety involves three steps: (1) the selection of superior plants; (2) selfing for several generations to produce a series of inbred lines, which although different from each other are each pure-breeding and highly uniform; and (3) crossing selected inbred lines. Webinbred line; instead, it has a proportion of the undesirable A-188 background, and theprogeny segregates for phenotypic characteristics and shows poor agronomic performance. In an effort to identify genotypes that combine a high somatic embryogenic response and good agronomic performance, we evaluated 48 advanced inbred lines developed at INTA.
WebMar 27, 2024 · Sunflower is a hybrid crop, and CWRs were used to develop cytoplasmic male sterile “female” lines and branching, fertility-restoring “male” lines for hybrid production. The male-restorer lines (PSC8, OQP8, and RHA438) generally had more introgressions than the female-maintainer lines (HA412, XRQ, IR, HA89, LR1, and HA300) ( SI Appendix, Fig. S16 ).
