A quick and reliable method for evaluating pollen quality is essential in a breeding program, especially in a crop such as banana that is characterized by high male and female sterility. In this study the germination and viability of banana pollen was evaluated in a sucrose solution and diluted b...

In 1990, observations were made on the nematode species profile on bananas in Oyugis district, Kenya. The country-wide survey was conducted in 1993 across 13 primary Musa growing districts. Observations were made on banana cultivars Nakyetengu (AAA) and Sukali Ndizi (AB). Considerable variation i...

This program will conduct research on various roots, tubers, and bananas to more fully realize the potential of these crops for improving nutrition, income generation, and food security among poor and vulnerable people, including women. Researchers and their partners will focus on conserving and ...

The susceptibility and sensitivity to Radopholus similis and Helicotylenchus multicintus of 2-month-old plants derived from sword suckers (early screening) and of sword suckers of established 18-month-old mats belonging to 12 Musa genotype was investigated and compared. Differences in nematode po...

For a mixture of reasons certain tropical crops which are important as primary or secondary food staples are relatively underresearched. The modem tools of molecular and cellular biotechnology offer the opportunity not only to make substantial gains in our knowledge of these crops, but also to ov...

IPM of banana weevil in Africa with emphasis on microbial control
Banana is the primary food crop in Uganda, but yields are low due to a complex of abiotic and biotic constraints. However, quantitative information on the importance, interactions, and geographic distribution of yields and constraints is scanty. We monitored yields, biotic and abiotic constraints...

Timing and distribution of attack on East African highland banana (Musa AAA- EA) by the banana weevil, Cosmopolites sordidus (Germar), (Coleoptera: Curculion- idae) was studied in a field trial at a farm 25 km NE of Kampala, Uganda. Weevils were released at three densities (5, 20 and 40 females p...
