Genetic diversity and combining ability analyses of provitamin A maize (zea mays L.) inbred lines for drought stress tolerance.
(2018)Abstract available in pdf. -
An investigative study of the drought tolerance of F1 maize (Zea mays L.) single crosses derived from PANNAR and CIMMYT inbred lines.
(2015)Drought is the most devastating abiotic stress limiting the production of maize (Zea mays L.) worldwide. The effect of drought stress is greatest in sub-Saharan Africa (SSA) where most small scale farmers rely on open ... -
Assessment of groundnut (Arachis hypogaea L.) for genetic diversity using agro-morphological traits and SSR markers.
(2019)Groundnut (Arachis hypogaea L.) offers one of the cheapest sources of proteins and economic empowerment to smallholder farmers in Africa, contributing significantly to world production and trade. Thus, improved groundnut ... -
Evaluation of early maturing maize (zea mays L.) hybrids for multiple-stress tolerance.
(2018)Maize (Zea mays L.) is the most important cereal in Africa, but a number of constraints including biotic, abiotic and socio-economic factors affect its production. The abiotic factors such as drought, low nitrogen (N) and ... -
The physiology of germination and dormancy in seeds of gynandropsi gynandra L. Briq syn Cleome gynandra L. (Cleomaceae).
(2018)The “spider plant” Gynandropsis gynandra L. Briq,” is an important traditional leafy vegetable in many parts of Africa. The species is considered underutilized and has been mainly neglected by research systems. Yields are ... -
Genotypey by environment interaction, genetic variability and path analysis for grain yield in elite soybean [Glycine max (L.) Merrill] lines.
(2018)Soybean [Glycine max (L.) Merrill] is the world’s leading source of protein and vegetable oil. However, its productivity is still low in the region due to limited availability of stable and high yielding cultivars. Therefore, ... -
Breeding for durable resistance to Cercospora Leaf Spot diseases in groundnuts (Arachis hypogaea L.) in Tanzania.
(2018)Lack of high yielding groundnut cultivars tolerant to Cercospora leaf spot disease (CLD) and stable across different environments is one of the challenges to groundnut production by smallholder farmers in Tanzania. This ... -
Evaluation of soybean [Glycine max (L.) Merrill] genotypes for grain yield and associated agronomic traits under low and high phosphorus environments.
(2018)Phosphorus is an important element for growth, development and seed formation in soybean and other plant species. This element is less available for plants. The capacity of absorbing phosphorus in the soil varies from one ... -
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, ... -
Evaluation of rice genotypes for grain yield and resistance to bacterial leaf blight (Xanthomonas oryzae pv.oryzae) disease.
(2018)Rice (Oryza sativa L.) is a staple food crop in many African countries including Tanzania. However, both regional and national rice production have failed to meet demand due to several constraints, among which is the ... -
Genetic variability, path coefficient and marker-trait association analysis for resistance to rosette disease in groundnut.
(2019-02)Several abiotic, biotic and socio-economic aspects constrain the production of groundnut (Arachis hypogea L.). Groundnut rosette disease (GRD) which can cause yield losses of up to 100% in susceptible cultivars, is among ... -
Determining heterotic orientation of South African maize inbred lines towards USA temperate and CIMMYT- tropical testers and genetic analyses under contrasting environments.
(2018)Drought and low soil fertility are major abiotic stresses limiting maize productivity in South Africa. Developing drought and low nitrogen-tolerant varieties is part of a long-term solution to improved maize productivity ... -
Evaluation of maize hybrids for low-nitrogen stress tolerance, yield stability and genetic purity.
(2019)Nitrogen stress is among the major abiotic constraints that impede maize production in Africa. Therefore, development of maize varieties that are tolerant to low N stress conditions and stable across environments is needed. ... -
Pre-breeding of wheat (Triticum aestivum L.) for Biomass allocation and drought tolerance.
(2018)Bread wheat (Triticum aestivum L., 2n=6x=42) is the third most important cereal crop globally after maize and rice. However, its production and productivity is affected by recurrent drought and declining soil fertility. ... -
Grain yield stability, genetic gain and path coefficient analyses in advanced soybean (Glycine max (L.) Merr.) lines.
(2017)Zambia is among the top 20 leading global producers of soybean (Glycine max L. Merr.) but adequate production is still hampered by low productivity. The yields of soybean in Zambia average below 3.0 t/ha against a yield ... -
Genetic analysis and improvement of groundnut (Arachis hypgaea L.) for drought tolerance and seed yield in Malawi.
(2018)Groundnut (Arachis hypogaea L,) is one of the major sources of food and income for smallholder farmers in Malawi. It is a valuable food security crop that supplies fats and proteins to the predominantly maize–based Malawian ... -
Genetic analysis of upland rice for grain yield and some agronomic traits under Striga hermonthica infestation in Uganda.
