Study sheds new light on roles of women and men on RTB farms

Oct 14, 2019 rtbcomms

Results from a household survey of farmers in Rwanda and Burundi challenge our stereotypes about how women and men engage in growing roots, tubers and bananas. In male-headed households, decision-making and labor-provision were most of the time joint efforts by men and women, while in female-headed households, men made most of the decisions and supplied […]

Scientists show which genetic loci is associated with bunch weight in highland banana

Oct 1, 2019 rtbcomms

Scientists have, for the first time, located the position of major quantitative trait loci associated with bunch weight and its component traits in Matooke, the East African Highland cooking banana. This is an important breakthrough in efforts to speed up the breeding of improved high-yielding varieties for both food security and improved household incomes in […]

More equitable crop improvement

Sep 19, 2019 rtbcomms

Ensuring plant breeders can take women into account M9 is the code name of a new banana variety developed for the smallholder banana farmers of Uganda, where banana is a very important staple. Yields can be 60% higher and, because the variety is resistant to pests and diseases, it does not need to be replanted […]

Researchers look deep under the banana’s skin

Sep 5, 2019 rtbcomms

The very thing that makes bananas so easy to eat – they don’t have seeds – also makes them hard to breed. Beneath that simple observation, however, lies a very complicated evolutionary history, one that three recent papers by researchers with the CGIAR Research Program on Roots, Tubers and Bananas help to uncover and, as […]

Guiding farmers to safer use of pesticides in Rwanda and Burundi

Aug 8, 2019 rtbcomms

It’s hard to overstate the importance of root, tuber, and banana (RTB crops) for smallholder farmers in the Great Lakes region of Central Africa. Thousands of farming households here depend on orange-fleshed sweetpotato, cassava, east African cooking banana and table potato for their daily meals. These families also rely on the cash generated from the […]

Climate change and rising population put pressure on essential crops in low-income regions

Jul 22, 2019 rtbcomms

Crops such as bananas, potatoes, and cassava are essential to food security in the world’s poorest regions. By 2050, their importance will increase, but climate change and population growth will put unprecedented pressure on production.  Climate change and population growth are increasing concerns for global food security. Modeling future agricultural trends that account for these […]

How RTB researchers try to develop the potential of RTB seed systems

Jul 18, 2019 rtbcomms

Roots, tubers and bananas share one characteristic that unites them in the CGIAR Research Program on Roots, Tuber and Bananas (RTB): farmers multiply them vegetatively, rather than as true seeds produced by sexual reproduction. Of course, they are also extremely important for the food security, nutrition and livelihoods of the most resource-poor farmers on Earth. […]
