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 ). WebIn plants, an inbred line consists of individuals that are genetically very similar.

Webcrossing two unrelated, homozygous inbred lines. Traditionally, the maize plants’ cross-breeding nature required recurrent self-pollinations for 6–10 generations, i.e., 3–5 years when two seasons per year can be accomplished, to obtain sufficiently homozygous inbred lines [13]. Inbred lines are genotypes that are developed to be used as WebInbreeding generally leads to loss in yield; the inbred lines yield much less than the open pollinated varieties from which they are derived. Heterosis is generally expressed as an increase in yield of the hybrid. Commercially this phenomenon is of great importance as an objective of plant breeding. 4.
