“…In contrast to a plethora of previous studies (Chipeta, Shanahan, Shanahan, Melis, Sibiya, & Benesi, 2016;Okechukwu & Dixon, 2009;Okogbenin & Fregene, 2002;Olasanmi et al, 2014Olasanmi et al, , 2017, we suggest that the late-bulking cassava genotypes are the key genotypes to target for nutritional food security. Our results suggest that the increased soil-root contact and foraging strategy of late bulking varieties is the driver of increased calcium and zinc concentrations in the F I G U R E 4 Analysis of cassava root development: (a) Accumulation of root system biomass differs between early and late-bulking genotypes.…”

“…With all that said, the environment should be taken care of during the aforementioned development . With rice an maize being the first and second most significant source of calories respectively, cassava is the third most grown plant in the subtropical and topical areas of Africa, Latin America and Asia ∼262,585,741 tonnes of cassava was produced worldwide in 2012 where Nigeria, Thailand, Brazil and Indonesia topped the producer list . Besides, an advantage of cassava is that is can be grown on marginal lands and bad soils as it is tolerant to bad weather and drought.…”

Cassava: Its polymer, fiber, composite, and application

2015

View full text Add to dashboard Cite

Cassava is a type of plant which has different purposes of use. It is used to produce various foods, biofibers, bio-composites, and bio-polymers. Besides, it is now used as renewable energy source of starch. The intention of the paper is to focus on the importance of cassava fibers, polymers, and composites as well as its potential applications, another focus point of this research is the biodegradable polymer development which is taken out from cassava starch. Moreover, this work gives a comprehensive review about surface treatments as well as the most recent developments of cassava polymer/fiber based bio-composites and the summary of main result presented in the literature, focusing on properties of cassava composite and applications. These applications were related to various industrial application as well as others such as the production of xylenes, ethanol and bio-fuel, food, food packaging and cassava foam. POLYM.

“…Two SSR markers, NS1099 and NS346, have been linked to CGM resistance (Macea Choperena et al, 2012 ). SSR markers associated with early bulking, a physiological trait in cassava, have also been identified (Olasanmi et al, 2014 ).…”

QTL Mapping for Pest and Disease Resistance in Cassava and Coincidence of Some QTL with Introgression Regions Derived from Manihot glaziovii

et al. 2017

Genetic mapping of quantitative trait loci (QTL) for resistance to cassava brown streak disease (CBSD), cassava mosaic disease (CMD), and cassava green mite (CGM) was performed using an F1 cross developed between the Tanzanian landrace, Kiroba, and a breeding line, AR37-80. The population was evaluated for two consecutive years in two sites in Tanzania. A genetic linkage map was derived from 106 F1 progeny and 1,974 SNP markers and spanned 18 chromosomes covering a distance of 1,698 cM. Fifteen significant QTL were identified; two are associated with CBSD root necrosis only, and were detected on chromosomes V and XII, while seven were associated with CBSD foliar symptoms only and were detected on chromosomes IV, VI, XVII, and XVIII. QTL on chromosomes 11 and 15 were associated with both CBSD foliar and root necrosis symptoms. Two QTL were found to be associated with CMD and were detected on chromosomes XII and XIV, while two were associated with CGM and were identified on chromosomes V and X. There are large Manihot glaziovii introgression regions in Kiroba on chromosomes I, XVII, and XVIII. The introgression segments on chromosomes XVII and XVIII overlap with QTL associated with CBSD foliar symptoms. The introgression region on chromosome I is of a different haplotype to the characteristic “Amani haplotype” found in the landrace Namikonga and others, and unlike some other genotypes, Kiroba does not have a large introgression block on chromosome IV. Kiroba is closely related to a sampled Tanzanian “tree cassava.” This supports the observation that some of the QTL associated with CBSD resistance in Kiroba are different to those observed in another variety, Namikonga.
