Bunch weight increase is one of the major objectives of banana improvement programs, but little is known about the loci controlling bunch weight and its component traits. Here we report for the first time some genomic loci associated with bunch weight and its component traits in banana as reveale...

A field experiment was established in the humid forest of southeastern Nigeria to assess host plant response to nematodes. Fifteen plantain and banana polyploid cultivars (landraces and hybrids) were tested in nematode-infested and non-infested fields on both plant and ratoon crops. The main nema...

Bunch orientation is an economically important trait in plantain ( Musa spp. AAB group) and banana ( Musa spp. AAA or ABB groups). Pendulous bunches are more symmetrical than subhorizontal, horizontal, or erect bunches and are, therefore, better adapted for transportation. Erect, horizontal, subh...

Triploid plantains (Musa AAB) are among the most important horticultural crops of West Africa. However, all landraces are susceptible to black Sigatoka, a fungal disease caused by Mycosphaerella fijiensis, Morelet. To ameliorate the spread of this epidemic, exotic triploid cooking bananas (ABB), ...

Several primary tetraploids with desirable attributes have been selected by Musa breeding programs. Diploid parental stocks have become available for further genetic improvement of the Musa genome. Hence, new genome manipulations should be tested before they become routine in breeding programs. T...

Use of resistant host genotypes is an important component of an integrated approach to control black sigatoka, a disease caused by the fungus Mycosphaerella fijiensis Morelet. The objective of the present research was to determine the role of the major gene for black sigatoka resistance (bs1) in ...

The annual harvest of banana and plantain (Musa spp.) is approximately 145 million tons worldwide. About 85% of this global production comes from small plots and kitchen or backyard gardens from the developingworld, and only 15% goes to the export trade. Musa acuminata and Musa balbisiana are the...

Epidermal and histological characterization of Musa species and cultivars were carried out to investigate the descriptor value of calcium oxalate between groups and subgroups of cultivars. Epidermal peels of the bracts of selected plantain and banana cultivars stained with 0.01% safranin solution...
