Improving the efficiency of selection in conventional crossbreeding is a major priority in banana (Musa spp.) breeding. Routine application of classical marker assisted selection (MAS) is lagging in banana due to limitations in MAS tools. Genomic selection (GS) based on genomic prediction models ...

Genomic prediction in a multiploid crop: genotype by environment interaction and allele dosage effects on predictive ability in banana
Banana (Musa spp.) is an important crop in the African Great Lakes region in terms of income and food security, with the highest per capita consumption worldwide. Pests, diseases and climate change hamper sustainable production of bananas. New breeding tools with increased crossbreeding efficienc...

East African Highland bananas (EAHBs) are a subgroup of triploid (AAA genome) bananas of importance to food security in the Great Lakes region of Africa. Little is known about their genetic variation, population structure and evolutionary history. Ninety phenotypically diverse EAHB cultivars were...

A well-saturated genetic linkage map is valuable for fundamental and applied genetic research. Genetic linkage maps of two half-sib diploid banana populations were constructed using allele-specific-polymerase chain reactions (AS-PCRs), diversity array technology (DArT), and simple sequence repeat...

Pests and diseases have become major constraints to smallholder banana production in the highlands of East Africa. Biotic challenges to banana cultivation include fungi, bacteria, viruses, nematodes and insects. Host-plant resistance, developed either by conventional breeding or by application of...

The potato genotype ND4382-19 has Solanum chacoense Bitt. in its genetic background. Foliar alkaloid analysis of it and its progeny ND5873 (ND4382-19 × Chipeta) by gas chromatography–mass spectrometry (GC–MS) showed that, in addition to the expected alkaloids (solanidine, leptinidine, and acetyl-...

Corky ringspot disease (CRS) resistance is an ideal target trait for breeding using marker-assisted selection (MAS) due to the high variability in field disease incidence that complicates screening for resistance. To develop molecular marker(s) associated with CRS resistance, a linkage map was co...
