Likewise, emerging inflorescences of female parents were bagged with transparent plastic bags, to avoid natural crossing with alien pollen until the last flower was pollinated. They are a staple food cropin Ugandaand other Great Lakes countries, and are used to make matoke. “Tissue culture technology for the improvement of African plantains,” in Sigatoka Leaf Spot Diseases of Bananas: Proceedings of an International Workshop Held at San José, Costa Rica, 28 March–1 April 1989, eds R.

Matoke is a variety of banana indigenous to southwest Uganda. I. East African Highland bananas therefore respond to or seem to ‘worry’ more about K deficiency than drought stress. Of particular concern is the threat to food security in Africa, where the East African Highland bananas (EAHB) and plantains form the staple diet and only source of income to millions of Africans. . Appl. Banana streak virus and an associated filamentous virus disease complex of highland bananas in Uganda; an alarming outbreak threatening to wipe out Ugandan Bananas. East African Highland bananas Uganda: Ankole grower frustrated over low banana prices A drastic decline in prices of matooke (East African Highland bananas) has … Brown, A., Tumuhimbise, R., Amah, D., Uwimana, B., Nyine, M., Mduma, H., et al. f. sp. R: A Language and Environment for Statistical Computing. Genet. Field Crops Res. . Twenty-seven NARITA hybrids (mostly secondary triploids ensuing from the 4x × 2x) were selected for further evaluation in the East African region. The temperature is high: averaging 27°C during the warmest months (February, March and April) and 25°C in the coolest month (July) (Ortiz and Vuylsteke, 1995). (2001). “The genetic improvement of bananas and plantains (Musa spp. ‘KABANA 6H’) black sigatoka, nematode and banana weevil tolerant ‘matooke’ hybrid banana released in Uganda. All the EAHB that generated the tetraploids which were used in the 4x × 2x crosses producing NARITA cultivars, were from the Nfuuka clone set (Supplementary Table 3). “SH2095” was produced from the cross - [(“Sinwobogi” × “Tjau lagada”) × (“wild malaccensis” × “Guyod”)], while “SH2766” was generated from the cross - [“Tjau lagada” × (“wild malaccensis” × “Guyod”)] (Supplementary Table 3). Banana (Musa spp.) The following data were taken from April 1995 to December 2015 and used in the analyses: Pollination/crossing number, female parent, ploidy of the female parent, male parent, ploidy of male parent, date of pollination, harvest date, date of seed extraction, total number of seeds, number of good seeds (with black hard integuments), number of bad seeds (with brown soft integuments), date of embryo extraction, number of extracted embryos, number of germinated embryos after two months, contaminations, number of weaned plants, and number of hardened plants ready for planting in the field. (2016). The origin of an edible diploid and the significance of interspecific hybridisation in the banana complex. (00°31′ 47″ N and 32°36′ 9″ E) and with an average temperature of 22°C and average annual rainfall of 1264 mm (Nsubuga et al., 2011). The first efforts toward banana research in the East African region can be traced back to 1948, when a survey was conducted in Kenya, Uganda, Tanganyika and Zanzibar, under the auspices of the Banana Research Scheme (Baker and Simmonds, 1951).
