There are 84 distinct cultivars of highland bananas (Musa spp.) in Uganda, grouped in five clone sets and it is not known which among these are female fertile. The objective of the study reported herein was to identify female fertile highland bananas that can be used in a cross breeding program a...

Banana is an important food and cash crop in Uganda. The crop displays wide diversity but the genetic relationship between and withing cultivars is largely unknown. A study was conducted to assess genetic relationships among 'Sukali Ndizi' clones collected from 16 different localities in Uganda ...

Low maize yields and the impacts of climate change on maize production highlight the need to improve yields in eastern and southern Africa. Climate projections suggest higher temperatures within drought-prone areas. Research in model species suggests that tolerance to combined drought and heat st...

Maize, the main dietary staple in Kenya, is one of the crops most susceptible to contamination by aflatoxin. To understand sources of aflatoxin contamination for home grown maize, we collected 789 maize samples from smallholder farmers’ fields in Eastern and South Western, two regions in Kenya re...

Background
The phenological development of the maize crop from emergence through flowering to maturity, usually expressed as a rate (i.e. 1/duration), is largely controlled by temperature in the tropics. Maize plant phenological responses vary between varieties and quantifying these responses can...

Cultivated bananas originated from interspecific hybridisation of two wild diploid (2n = 2x = 22) species, Musa acuminata and M. balbisiana that were the donors of the A and B genomes, respectively. Most cultivated bananas are triploids with 2n = 3x = 33 chromosomes. They vary in genome compositi...
The East African highland banana (Musa spp. AAA) is an economically important food crop. The crop is affected by a number of diseases and pests. Genetic improvement of the crop is hindered by very low seed set and poor seed germination. The objective of this study was to compare seed set, seed qu...
