Phenotypic and serological evaluation of cowpea (Vigna unguiculata l. Walp) genotypes for resistance to viral infection

Viral infection is a challenge to sustainable cowpea productionand can cause up to 100 % yield losses which warrant identification of sources of resistant genotypes for cultivation. Nine cowpea genotypes were evaluated in a field trialinvolvingrandomized complete block design with 4 replications. Reactions of the plants to viral disease weredetermined at 2, 4 and 6 weeks after planting (WAP) based on disease symptoms using...

The toxicity and repellency action of essential oils from Lippia javanica and Microglossa pyrifolia against Sitophilus zeamais (maize weevil)

The efficacy of two plant essential oils and their ground powders(Lippia javanica and Microglossa pyrifolia) in reducing post-harvest loss caused by Sitophilus zeamais in maize was determined in the laboratory. Each plant powder and essential oil was tested by exposing adult weevils of mixed sex to two levels of 2 and 4 g/20 g of grains and 0.5 and 2.0 ml/100 g of grains for plant powders and essential oils respectively...

Impact of climate change on armyworm infestation on maize in Nigeria: A review

Maize (Zea mays) is an important food crop in Nigeria, and it is fast becoming the most widely cultivated crop. Several efforts have been made by Nigeria government to make the country self-sufficiency in maize production but some biotic and abiotic factors are impeding problems. Among the biotic constraints militating against maize production in Nigeria, armyworm (Spodoptera frugiperda) is most devastating in the recent...

Repeatability and number of harvests required for selection in coconut hybrid varieties

In the breeding of perennial plant species, the coefficient of repeatability is an important parameter because it allows effective early selection of superior genotypes, thus saving time and cost. The objective of this study was to determine the minimum numbers of years required for observation to identify superior genotypes of coconut with high degree of accuracy. Four hybrid varieties of coconut were evaluated in a...

Compatibility studies in Cola nitida genotypes

Cross and self-pollination compatibility studies were carried out using 10 Cola nitida genotypes from the Cocoa Research Institute of Nigeria, Ibadan. The few genotypes that were self-pollinated tended to show low pod production; whereas, crosses between the genotypes showed higher pod production. These data would suggest that multiple genotypes should be included in plantations to achieve higher levels of...

Incidence of seed borne fungi in farm saved rice seeds, quality declared seed and certified seed in Morogoro Region in Tanzania

Rice (Oryza sativa L.) is the second most important food crop after maize in Tanzania. It faces many challenges like diseases, pests and physical damages, which reduce the seed quality. This article identified microorganisms and the district where they occurred. 13 fungal species comprising of 11 pathogenic and 2 saprophytic fungi were detected and the incidence level varied among sample. Mvomero District showed the...

Post-harvest evaluation of selected inbred lines to maize weevil Sitophilus zeamais resistance

Maize weevil (Sitophilus zeamais Motschulsky) is a major maize (Zea mays L.) storage insect pest in the tropics which reduces the quantity and quality of maize hence facilitating establishment of aflatoxin and other mycotoxins. The objective of this study was to evaluate maize weevil resistance on selected inbred lines. Twenty eight inbred lines with 2 checks (MTPO701-reistant and Duma 41-susceptible) were used in this...

Genotypes × Environment interaction analysis for Ethiopian mustard (Brassica carinata L.) genotypes using AMMI model

The genotype x environment interaction (GEI) has an influence on the selection and recommendation of genotypes. To this end, G x E interaction and grain yield stability study was conducted for 17 advanced Ethiopian mustard across three districts (Sinana, Adaba and Agarfa) in the highlands of Bale zone during 2014 and 2015 main cropping season. Randomized complete block design with four replications was used. The combined...

Assessing the influence of volatiles compounds produced by flowers of three leguminous plants on the host foraging behavior of the parasitoid Apanteles taragamae Viereck, a larval parasitoid of the cowpea pod borer Maruca vitrata Fabricius

The importance of volatiles produced by three Maruca vitrata host plant in host foraging by the parasitoid Apanteles taragamae was assessed in laboratory conditions. Different odor sources consisted of uninfested flowers, mechanically damaged flowers, M. vitrata-infested flowers and clean air arranged in various combinations were tested using a Y-tube olfactometer. The influence of volatiles produced by flowers of three...

Agro-morphological variability of pearl millet (Pennisetum glaucum (L.) R. Br) accessions planted in arid and semi-arid region in part of Kenya

The experiment was conducted in Marigat and Koibatek in Kenya from 2013 to 2014 under irrigation conditions in two environments. The main objective of the study was to investigate the morphological variability of 36 pearl millet (Pennisetum glaucum L.) accessions sourced from ICRISAT Kenya. Eight agro-morphological parameters were measured using the pearl millet descriptors. The experimental design was randomized complete...

Relationship between the efficiency of selection using combining ability and multiple traits selection indices in extra early tropical maize (Zea mays L.) under low nitrogen condition

Infertile soil mainly due to low nitrogen (N) has become an important abiotic stress affecting maize production. Progress in breeding for varieties that tolerate low-N stress has been slow due to complex genetic control. Breeders have therefore resulted to the use of secondary traits in multiple traits selection indices for selection of best genotypes under low-N condition. The objectives of this study were to identify...

Soil chemical properties and garden egg (Solanum spp) performance under different organic amendment

Field experiments were conducted during the growing seasons of 2012 and 2013 at the experimental farm of National Horticultural Research Institute Mbato out-Station Okigwe, Imo State, Nigeria to evaluate the effect of different organic amendments on some soil chemical properties and performance of five garden egg varieties. The treatments were five garden egg varieties (Solanum gilo, Solanum aethiopicum, Solanum...
