Genetic diversity of proprietary inbred lines of sunflower, determined by mapped SSR markers and total protein analysis.
(2008)This study compared DNA based SSR markers with total seed protein markers, used to evaluate genetic diversity of sunflower. The multiplex-ability, cost effectiveness and applicability of microsatellites as molecular markers ... -
Genetic diversity of sorghum (Sorghum bicolor L. Moench) germplasm and hybrid potential under contrasting environments in Mozambique.
(2017)Abstract available in PDF file. -
Genetic diversity, stability, and combining ability of maize genotypes for grain yield and resistance to NCLB in the mid-altitude sub-humid agro ecologies of Ethiopia.
(2013)Maize (Zea mays L.) is the third most important cereal crops in the world after wheat and rice. In Ethiopia, maize remains the second largest food security crop after tef [Eragrostis tef (Zucc.) Trotter.]. The mid-altitude, ... -
Genetic enhancement of sweetpotato for weevil (Cylas spp.) resistance, storage root yield and yield-related traits.
(2017)Sweetpotato (Ipomoea batatas [L.] Lam.) is an important crop providing livelihood and economic opportunities for millions of smallholder farmers in sub-Saharan Africa (SSA). Weevil infestation caused by sweetpotato weevil ... -
Genetic gain, advanced cycle pedigree breeding and correlated response to selection under varying moisture conditions in sunflower.
(2013)Sunflower (Helianthus annuus L.) is one of the most important oil crops in South Africa and genetic improvement for grain yield and oil-content was initiated in the country in the early 1970s. Commercial production of ... -
Genetic improvement of cowpea [vigna unguiculata (L.) walp.] for grain yield and yield component components in Zambia.
(2020)Abstract available in pdf. -
Genetic improvement of grain yield and quality in rice (Oryza sativa L.) in South Sudan.
(2017)Abstract available in PDF file. -
Genetic Improvement of pigeonpea (Cajanus cajan (L.) Millsp.) for Fusarium wilt resistance in Tanzania.
(2016)Abstract available in PDF file. -
Genetic improvement of pigeonpea [Cajanus cajan (L.) millspaugh] for yield, earliness and resistance to Fusarium wilt (Fusarium udum Butler) in Malawi.
(2020)Pigeonpea [Cajanus cajan (L.) Millspaugh, 2n=2x=22] is a one of the important food legumes in Sub-Saharan Africa and Asia. Malawi is a major pigeonpea grower in Africa with production of 403,519 tonnes produced in 248,400 ... -
Genetic improvement of Zambian maize (Zea mays L.) populations for resistance to ear rots and a survey of associated mycotoxins.
(2009)Maize ear rots are among the most important impediments to increased maize production in Africa. Besides yield loss, they produce mycotoxins in their host whose contamination has been linked to several human and animal ... -
Genetic studies and recurrent selection for nematode resistance in maize.
(2010)Plant-parasitic nematodes cause grain yield loss in maize. The most important genera of plant-parasitic nematodes demonstrated to be of economic importance to maize are Pratylenchus spp., Meloidogyne spp. and Heterodera ... -
Genetic studies of grain and morphological traits in early generation crosses of Malawi rice (Oryza sativa L.) Landraces and NERICA varieties.
(2010)Rice (Oryza sativa L.) is the second most important cereal crop in Malawi. Rice productivity in the dominant (85%) rainfed ecosystem is very low, with mean yield of only 1.4 t ha-1. Farmers plant traditional landraces that ... -
Genetic studies of quantitative and quality traits in rice under low and high soil nitrogen and phosphorous conditions, and a survey of farmer preferences for varieties.
(2010)Rice is an important crop ranking third after maize and wheat in Kenya. Its demand is growing at 12% per annum, while production has stagnated for quite a number of years. This situation has lead to consumption outstripping ... -
Genetic studies of secondary traits and yield heterosis in maize under high and low nitrogen conditions, incorporating farmer perceptions and preferences for varieties.
(2010)In Tanzania, 85% of the population depend on maize for food security; it provides 60% of their dietary calories and about 50% of their protein. It is not only a source of food security, but is also a cash crop on which ... -
Genetic studies on drought tolerance and grain shattering in rice.
(2010)Grain yield of rice can be enhanced by breeding for drought tolerance and optimum shattering. New generations of rice, the interspecific fixed lines known to carry more drought tolerance traits, are a potential source for ... -
Genetic studies on head architecture, adaptation and blast resistance of finger millet in Uganda.
(2013)Finger millet is the second most important cereal in Uganda after maize. The yields however, have remained low due to several constraints, such as finger millet blast disease and limited technology options. Therefore ... -
Genetic studies on host plant resistance to Mexican bean weevil (Zabrotes subfasciatus Boheman) in Ethiopian common bean (Phaseolus vulgaris L.) germplasms.
(2017)The common bean (Phaseolus vulgaris L.) is the second most important food legume in Ethiopia. It is the most important cash crop for the smallholder farmers and has a significant impact on the national economy. However, ... -
Genetic studies on host-plant resistance to bean fly (Ophiomyia spp.) and seed yield in common bean (Phaseolus vulgaris) under semi-arid conditions.
(2010)Bean fly (Ophiomyia spp.) is a major pest of common bean (Phaseolus vulgaris L.) throughout eastern and southern Africa. In the semi-arid areas, apart from drought, the insect pest is reported to cause high crop losses up ... -
Genetic study of cowpea (Vigna unguiculata (L.) Walp) resistance to Striga gesnerioides (Willd.) vatke in Burkina Faso.
(2010)In Burkina Faso, the existence of different races of Striga gesnerioides (Willd.) Vatke, with apparent variable aggressiveness on cowpea (Vigna unguiculata (L.) Walp) renders the breeding task very complex. Therefore, a ... -
