WebOvercoming hybridization barriers in potato. Plant Breeding Conference Proceedings. 125:1-12. Interpretive Summary: The cultivated potato is a major crop worldwide. It is a high input crop with complex quality requirements at harvest and during storage. WebNov 14, 2016 · A major bottleneck to introgressive hybridization is the lack of genome collinearity between the donor (alien) genome and the recipient crop genome. Structural differences between the homeologs may create unbalanced segregation of chromosomes or cause linkage drag. To assess large-scale collinearity between potato and two of its wild …

WebHybridization is essential for gene introgression in plant breeding. However, embryo abortion may prevent the production of hybrid seeds because of post-zygotic genetic barriers. A breeding program for ornamental Capsicum did not achieve seed germination using crosses of two accessions, although both accessions were from C. annuum var. … WebOvercoming hybridization barriers in potato S.
