“…The low heritability values obtained in the current study suggests that environmental factors play a big role in inheritance of resistance to Foc race 1 and therefore, selection based on phenotype is not recommended. Dutta et al (2013) and Bushra et al (2017) reported that selection based on phenotype performance is more effective when the heritability estimates are significantly high. It is, therefore, commendable to use molecular markers when selecting for pest and disease resistances in Musa spp.…”

Fusarium wilt of bananas (Musa spp.), caused by Fusarium oxysporum f. sp. cubense (Foc) causes up to 100% yield loss in bananas. Foc race 1 in particular is very devastating to dessert bananas in Uganda. One of the effective control strategies for the disease is the development of resistant cultivars through breeding. The objectives of this study were to identify suitable banana germplasm for generating a segregating population for resistance to Foc race 1 and understand the mode of inheritance of resistance to Foc race 1. Twenty-two banana accessions sourced from the National Agricultural Research Organisation in Uganda were challenged with Foc race 1 in a screen house experiment. Monyet, resistant to Foc race 1 and Kokopo, susceptible, were selected and crossed to generate 142 F1 genotypes. These F1 genotypes were also challenged with Foc race 1 in a screen house experiment. Data were collected on rhizome discoloration index (RDI), leaf symptom index (LSI) and pseudo-stem splitting (PSS), and analysed for variability. The banana accessions evaluated showed varying degrees of resistance to Foc race 1. Segregation ratios for resistant versus susceptible progenies fitted 13:3 (χ2 = 0.12, P = 0.73) for RDI and 11:5 (χ2 = 3.04, P = 0.08) for PSS. Estimated broad sense heritability was 27.8% for RDI, 13.9% for LSI and 14.7% for PSS. The results suggest that resistance to Foc race 1 in banana is controlled by at least two dominant genes with epistatic interaction and that heritability of resistance to Foc race 1 is low in Musa spp.

“…Itoffer a rich scope for creation, conservation, and utilization of genetic variability for the improvement of plants (Sharma et al, 2012;Gaikwad et al, 2017). Tissue culture techniques have been used for mass multiplication of plants and their conservation (Gosal et al, 2010;Hussain, et al, 2012;El Meskaoui, 2013;Ghaffar et al, 2016;Rashid et al, 2017;Oseni et al, 2018). These in vitro techniques (TC) also enjoyed enormous application for the production of secondary metabolites (Namdeo 2007;El Meskaoui, 2013).…”

There are many constraints that severely affect the global agricultural production and productivity which include the ever increasing of population growth, degradation of natural resources, climate changes and emerging pests. Among these factors, biotic constraints or pests are known to cause 25-50% or complete loss of plant production. Accordingly, various plant protection technologies have been deployed with the trend of focusing on the use modern biotechnological tools that are proven to be most effective and mandatory. The review covers a wide array of pest management methods ranging from the conventional biological control methods up to molecular breeding techniques. Furthermore, the application of new genetic engineering techniques fueled by new breakthroughs and innovations are the cornerstone of this review. Accordingly, the continuous increasing trend of GM crops cultivation in both crop type and hectare has urged many countries to deploy the technology as a key strategy to enhance their bioeconomy. In fact, plant protection is the discipline that immensely benefit from biotechnology than any other disciplines for ensuring food security and sustainable development. However, in order to fully exploit the enormous potential of biotechnology, appropriate biosafety regulatory frameworks and proper stewardship programs need to be effectively implemented. This integrated approach can promptly help respond to the ever-dynamic threat of pests and hence reliably combat food insecurity and ably contribute to sustainable development. Int. J. Appl. Sci.

“…To maximize their productive potential, cultivated plants need adequate amounts of water, light, carbon dioxide and mineral nutrients (nitrogen, phosphorus, potassium, calcium, magnesium, sulphur and several microelements) [1][2][3][4][5][6][7][8][9]. Soil is the main source of mineral nutrients and water for plants.…”

“…It is important to keep in mind that oleaginous crop, compared to wheat and corn, reacts less efficiently to the application of chemical fertilizers. Therefore, excellent results can be obtained if natural fertilizers are used in the mentioned quantities [3,4,6,8,10,12,24,28].…”

The main objective of the current research is to determine the influence of some soil fertilizations systems on the variation of the content of magnesium, aluminium, potassium, chromium and manganese from the soil. The experiments have been carried out in a experimental field, for a soil cultivated with oleaginous crop. In the case when was applied the variant fertilizations with farmyard manure was registered the higher values of the nutrients content in soil like magnesium, potassium and manganese.
