Allelic variability of oil palm inter-population progenies based on simple sequence repeats markers
The genetic structure and variability was described among 52 oil palm inter-population crosses after two selection cycles using simple sequence repeats markers (SRR). The 10 sets of SSR markers covering 62.5% of the oil palm genome showed a high level of polymorphism (average number of alleles per locus = 6.7; unbiased expected heterozygosity = 0.655; G”st = 0.346) across the oil palm samples. On the basis of...

Potential of ten wild diploid cotton species for the improvement of fiber fineness of upland cotton through interspecific hybridization
Cotton is the highest source of natural fiber in textile industry worldwide. With the modern spinning technologies, the demand for cotton fiber with higher quality has increased, making the genetic improvement of fiber quality one of the main challenges for cotton breeders. In cotton breeding, wild species are important source of several desirable genes for genetic improvement of the main cultivated cotton Gossypium...

Establishment of an early selection method (criteria) for breeding in cowpea (Vigna unguiculata)
Populations with high genetic variability are targeted by breeders as they create opportunity for selection and genetic improvement. To achieve this, multiple populations are created, but resources are often scarce. This calls for identification of populations with the desired traits at early generation. The study was carried out at MUARIK in seasons 2017A and 2017B on 135 F2 and 40 F3 cowpea populations respectively...

Harnessing genotype-by-environment interaction to determine adaptability of advanced cowpea lines to multiple environments in Uganda
This study was conducted to determine the yield stability of advanced cowpea lines in diverse agro-ecological zones of Uganda in order to facilitate documentation requirements for national performance trials (NPT). Thirty cowpea genotypes were evaluated against six checks in three localities, over three growing seasons, making a total of 9 unique environments. The trials were laid in a 6x6 alpha lattice design with...

Selection of drought tolerant genotypes in groundnut (Arachis hypogaea L.) using indices
A study was carried out to evaluate the effect of drought stress on pod yield and other traits of groundnut genotypes to select the ten best performing genotypes using indices. Ninety six genotypes including 90 F2:3 progenies, 4 parents and 2 checks were planted under well-watered (WW) and water-stressed (WS) conditions at the International Crops Research Institute for the Semi-Arid Tropics ICRISAT, Mali. Six selection...

Genetic variation among white lupin (Lupinus albus L.) landraces from Northwestern and Southern Ethiopia for agronomic traits and nutrient contents of grain
White lupin (Lupinus albus L.) is rich in quality protein, relatively tolerant to drought, soil salinity and acidity, increase the fertility of soils and can contribute to improved agricultural sustainability, food security and reduce malnutrition which has close associations with climate change. This study was conducted to assess genetic variability of white lupin genotypes for agronomic traits and nutrient contents of...

Evaluation of improved pigeon pea (Cajanus cajan) varieties for organoleptic dal quality in India
Pigeon pea (Cajanus cajan L.) is an important pulse crop in the Indian diet and one of the most important sources of dietary protein for the population. Organoleptic qualities of pigeon pea dal were tested to draw conclusions on the preferred varieties. Organoleptic qualities such as taste, texture, aroma, tenderness, sweetness and overall acceptance were tested by a trained sensory panel. Available and...

Inheritance pattern of resistance to Fusarium wilt (Fusarium oxysporum f. sp sesame) in sesame
Fusarium wilts (Fusarium oxysporum f.sp. sesame) is among of the most destructive soil-borne disease of sesame in Uganda. The disease may cause yield loss of up to 100% if not controlled. Breeding and use of resistant varieties is the most economic and eco-friendly solution to the disease since majority of sesame growers are resource constrained. Some genotypes were reported to be moderately resistant to the disease in...
