INHERITANCE OF CATECHIN AND CAFFEINE CONTENT IN KENYAN TEA (Camellia sinensis (L.) O. Kuntze)
(University of Eldoret, 2014)
Diallel designs are used in many breeding programmes because of the important genetic information they offer to plant breeders. Eight biochemical traits were studied to estimate the general combining abilities (GCA), ...
SCREENING FOR STEM RUST RESISTANCE IN MUTANT BARLEY (Hordeum vulgare L.) LINES
(University of Eldoret, 2013)
Stem rust is a devastating disease in barley that is caused by a fungi (Puccinia graminis f.sp tritici, Eriks. and E. Henn).The disease has been controlled for quite some time due to the presence of cultivars carrying the ...
THE EFFECT OF IMPROVED SOLUBILITY AND UPTAKE OF LIME BY THE USE OF TRIPLE SUPER PHOSPHATE FERTILIZER AND SLUDGE ON CROP PRODUCTION
(University of Eldoret, 2015)
Soil acidity is one of the major problems that limit agricultural productivity. Improving fertilizer uptake is a key issue to sustainability of crop production. Fertilizer efficiency by most crops and farming systems is ...
THE COMBINING ABILITY OF SINGLE CROSSES AND THEIR REACTION TO MAIZE LETHAL NECROSIS VIRUS.
(University of Eldoret, 2019)
Maize is a key staple crop that is grown in most regions of Kenya and it is consumed in various forms by 80% of the population. Among the biotic constraints, maize lethal necrosis disease causes heavy yield losses thus ...
CHARACTERIZATION OF FINGER MILLET (Eleusine Coracana L. Gaertn.) GENOTYPES USING MORPHOLOGICAL TRAITS AND SIMPLE SEQUENCE REPEAT MARKERS
(University of Eldoret, 2013)
Finger millet is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation of finger millet germplasm is important for ...
DIVERSITY OF ELITE KENYAN BREAD WHEAT MUTANT LINES IN STEM RUST (Puccinia graminis f. sp. tritici) RESISTANCE
(University of Eldoret, 2018)
Stem rust caused by Puccinia graminis f. sp. tritici is a major constraint to wheat production in Kenya. The re-emergence of a new fungal race Ug99 and its variants have caused devastating losses to wheat production since ...
EVALUATION OF BEAN VARIETIES (phaseolus vulgaris L) FOR RESISTANCE TO bean common mosaic virus (BCMV) and bean common mosaic necrotic virus (BCMNV) ACROSS A SOIL FERTILITY GRADIENT IN WESTERN KENYA
(University of Eldoret, 2013)
Bean Common Mosaic and Bean Common Mosaic Necrosis are some of the most devastating diseases of common beans (Phaseolus vulgaris L) in Kenya. These viral diseases cause more than 80% yield losses. Control by chemical method ...
INTROGRESSION AND QTL MAPPING OF STEM RUST RESISTANCE GENES USING BI-PARENTAL WHEAT POPULATIONS
(University of Eldoret, 2018)
Rust diseases are a global challenge to wheat production, causing yield losses of up to 50% and even 100% in susceptible host cultivars. A virulent stem rust race named Ug99 (TTKSK) was discovered in Uganda in 1999, and ...
TAXONOMIC IDENTIFICATION OF ELEUSINE SPP. USING PLASTID GENES
(University of Eldoret, 2016)
Finger millet (Eleusine coracana subsp. Coracana) is a very promising crop to alleviate the problems of food scarcity and malnutrition in the semi-arid tropics and beyond because of its known wide ecological adaptability ...
GENOTYPE BY ENVIRONMENT INTERACTIONS FOR SUCROSE CONTENT IN SUGARCANE (Saccharum spp. hybrid) CLONES GROWN UNDER RAINFED CONDITIONS IN WESTERN KENYA
(University of Eldoret, 2017)
Sugarcane (Saccharum spp hybrid) refers to sucrose storing members of the family (poaceae) and is cultivated primarily for the extraction of sucrose (sugar) from the plant stalks. Recent uses of this tropical crop include ...
