Breeding erect plant type sweetpotato lines using cross breeding and gamma-ray irradiation

Breeding erect plant type sweetpotato lines using cross breeding and gamma-ray irradiation

Few sweetpotato (Ipomoea batatas Lam.) cultivars with erect plant type are available despite their advantages over spreading type, such as simplicity of cultivation and ability to adapt to limited space. One of the reasons is insufficiency of their agronomic characteristics for table use. So, it is important to overcome these drawbacks of ER-type lines. We attempted to breed new erect plant typ...

Pollen irradiation and variability in plant breeding materials

In a conventional breeding programme, all F1 plants, from homozygous self-fertilizing parents, are identically heterozygous. The F2 is produced, and the character combination selected for, is carried on further into daughter generations. In case the pollen was irradiated before pollination it would be investigated whether genetic changes had taken place which influence the variability in the pr...

Genomics and Plant Breeding

The recent announcements of the breakthroughs in obtaining the oil palm genome sequence map herald a new chapter in oil palm genetic improvement. These breakthroughs will spur the further development of oil palm genomics. This article examines how genomics would impact plant and oil palm breeding. The knowledge derived from genomics research in terms of the DNA structure of a gene, how it funct...

Evolution of plant breeding

Plant breeding is considered one of the longest ongoing activities undertaken by humans, who select plants more productive and useful to themselves and the animals for at least 10,000 years ago. The evolution of civilizations paralleled the success of plant breeding, although this has not been recognized by the public. The reason may be lack of understanding of what plant breeding encompasses. ...
