Population diversity of rice bacterial leaf blight isolates in Uganda
(Pelagia Research Library, 2013)The deployment of resistant cultivars is the best option to control bacterial leaf blight (BLB) and requires an understanding of the pathogen diversity. BLB caused by Xanthomonas oryzae pv.oryzae is a destructive disease ... -
A preliminary analysis of diversity among East African sweet potato landraces using morphological and simple sequence repeats (SSR) markers
(International Society for Hoticultural Science, 2006)East Africa is known to have a wide range of sweet potato landraces and, therefore, is considered to be a secondary center of diversity. In this study, we assessed the diversity among sweet potato landraces from Kenya, ... -
Variability of grain-filling traits in early maturing CIMMYT tropical maize inbred lines
(Crop Science Society of America, 2014)Grain-filling rate (GFR), effective grain-filling duration (EGFD), and total grain-filling duration (TGFD) are important physiological traits of maize (Zea mays L.) grain yield (GY) formation. To devise effective breeding ... -
Exploiting grain-filling rate and effective grain-filling duration to improve grain yield of early-maturing maize
(Crop Science Society of America, 2013)Early-maturing maize (Zea mays L.) genotypes yield 15 to 30% less than late-maturing genotypes. One strategy for improving grain yield in the early-maturing group involves assessment of grain-filling traits as secondary ... -
A comparative analysis of conventional and marker-assisted selection methods in breeding maize streak virus resistance in maize.
(Crop Science Society of America, 2009)Reliable information regarding comparative advantage of marker-assisted selection (MAS) over conventional selection (CS) in breeding for maize streak virus (MSV) resistance in maize (Zea mays L.) is scarcely available. A ... -
Evaluation of rhizobial inoculants on the productivity of soybean varieties grown on an acidic soil in Rwanda
(Makerere University, 2014)Several high yielding soybean varieties have been introduced in Rwanda but yields have remained low and even declining especially in areas with acidic soils. Consequently a number of rhizobial inoculants were introduced ... -
Stability of Barley genotypes for earliness, yield and resistance to leaf scald disease in Ethiopia
(2014-12)Scald, caused by Rhynchosporium secalis (Oud) Davis, is the most widely distributed and destructive disease of barley (Hordeum vulgare) in Ethiopia. Developing genetic resistance in early maturing genotypes is a viable ... -
Evaluation of yam bean (Pachyrhizus spp.) accessions for root yield and nutritional quality under different agro ecologies in Uganda.
(Makerere University, 2013-08)Yam bean (Pachyrhizus spp.) is one of the legume root crops that is exclusively used for its storage roots. The yam bean has three closely related cultivated species: P. tuberosus (Lam.) Sprengel, P. erosus (L.) Urban, and ... -
Farmers’ willingness to pay for irrigation water: The case of Doho rice irrigation scheme in Eastern Uganda
(Makerere University, 2014-12)The government of Uganda is currently rehabilitating three major irrigation schemes whose infrastructure had broken down due to poor maintenance. Among these schemes is Doho rice irrigation scheme. It is expected that after ... -
Evaluation of Ugandan sorghum accessions for cytoplasm male sterility status and combining ability for hybrid development.
(2014)In sorghum, a predominantly self-pollinated crop, hybrid seed production relies exclusively on the cytoplasmic-genetic male sterility system. The system of hybrid development requires sorghum breeding programs to develop ... -
Evaluation of the usefulness criterion to identify Bi-Parental maize populations with the best potential for producing superior inbreds.
(Makerere University, 2014)Because resources are obviously restricted, it is not possible to advance all the progenies generated to later generations, so there is need to reduce the number of populations that will be subject to intensive testing and ... -
Influence of mineral zinc application on plant zinc biofortification, protein content, yield and nodule activity of bush bean genotypes.
(Makerere University, 2014)Legumes contribute considerably to human dietary mineral requirements and proteins in Sub-Saharan Africa (SSA). Bush bean (Phaseolus vulgaris L.) in particular, is a key staple crop in the region. The crop is recognised ... -
Evaluation of resistance to bruchids within the common dry bean germplasm in Uganda.
(2014)Dry bean (Phaseolus vulgaris L.) is economically and nutritionally an important legume in many parts of Africa and Latin America. Unfortunately, two bruchid species, Acanthoscelides obtectus Say, and Zabrotes subfasciatus ... -
Performance of starter pigs fed diets based on malted and fermented maize.
(Makerere University, 2014)Two growth trials involving crossbred (Large white x Landrace) starter pigs were conducted to compare feed intake, growth rate, feed conversion efficiency and cost of feeding malted (MTD), fermented (FTD), fermented maize ... -
Determinants of participation of small holder farmers in marketing of grain amaranth: A case of Kamuli District, Uganda.
(Makerere University, 2014)As a vegetable crop, grain amaranth plays an important role in improving household nutritional and economic status. Grain amaranth is still a new crop in Uganda's farming system, after being introduced by VEDCO in 2005 to ... -
Heritability analysis of drought adaptation traits in sweet potato.
(Makerere University, 2014)Sweet potato is a key food security crop in Uganda whose per capita consumption is third to bananas and cassava. Drought is among the major constraints to sweet potato production in Uganda. A part from decreasing tuber ... -
Insect vectors of Xanthomonas campestris pv musacearum: Distribution across altitudes, seasons and banana cultivars in Rwanda.
(Makerere University, 2013-10)Xanthomonas Wilt of banana (XW) is a devastating bacterial disease in Rwanda. To gain an improved understanding on the management of XW, two studies were carried out in Rwanda. Data were collected mainly on identification ... -
Performance of low phosphorus tolerant bean genotypes on acidic soils of Rwanda.
(Makerere University, 2014-06)In eastern Africa, bean (Phaseolus vulgaris L.) production is highly limited by soil fertility decline, particularly phosphorus (P); yet the typical small-scale farmers are incapable of accessing the often recommended means ... -
Transgenic breeding of sweet potato for resistance to African weevil (Cylas puncticollis).
(Makerere University, 2014-08)Sweet potato weevil (Cylas puncticollis) Boheman is a serious pest throughout Sub-Saharan Africa. The pest causes up to 28% production losses annually in Uganda. Due to difficulties to implement pest management measures ... -
