One of the objectives cassava-breeding project at CIAT is identification clones with special root quality characteristics. A large number self-pollinations have been made in search useful recessive traits. During 2006 harvests an S1 plant produced roots that stained brownish-red when treated iodine solution, suggesting it had lower-than-normal levels amylose its starch. Colorimetric and DSC measurements indicated low (3.4%) absence starch, respectively. SDS-PAGE demonstrated GBSS enzyme...
Abstract Cassava ( Manihot esculenta Crantz) is one of the most important sources starch in tropics. There limited and contradictory information regarding cassava characteristics. The International Center for Tropical Agriculture (CIAT) holds trust FAO's germplasm collection. Starches from 3272 landraces (including 12 wild relatives) 772 improved clones were extracted analyzed over a period several years. In cases only sample per genotype was analyzed. Average cyanogenic potential 327 ppm...
Functional properties of normal and waxy starches from maize, rice, potato, cassava as well the modified maize starch COLFLO 67 were compared. The main objective this study is to position recently discovered spontaneous mutation for amylose-free in relation other with well-known characteristics. Paste clarity, wavelength maximum absorption (lambda(max)), pasting properties, swelling power, solubility, dispersed volume fraction measurements gel stability (acid alkaline resistance, shear,...
ABSTRACT Improving total carotenoids content (TCC) in cassava roots is an important strategy to reduce vitamin A deficiency human populations that rely on as a source of energy their diets. The high heritability for TCC the allowed International Center Tropical Agriculture implement rapid cycling recurrent selection approach reduced standard length each cycle from ordinary 8 yr 3. Data successive evaluation nurseries suggested gains have been made through time. However, no comparison...
The quality of cassava starch, an important trait in breeding programs, determines its applications various industries. For example, development waxy (having a low level amylose) is demand. Amylose synthesized by granule-bound starch synthase I (GBSSI) plants, and therefore, down-regulation GBSSI expression might lead to reduced amylose content. We produced 63 transgenic plant lines that express hair-pin dsRNAs homologous the conserved region under control vascular-specific promoter p54/1.0...
The morphological, physical, and chemical characteristics of 23 unripe cultivated varieties Colombian Musaceae were assessed. Fresh pulp dry matter helped to discriminate the following consumption subgroups: FHIA dessert hybrids (hydes: 24.6%) < bananas (des: 29.4%) nonplantain cooking (cook: 32.0%) (hycook: 34.2%) plantains (pl: 41.1%). Banana flour starch content on basis (db) varied from 74.2 88.2% among varieties, with: pl: 86.5% > cook hycook: 84% des: 81.9% hydes: 79.7% (p <or= 0.01)....
"Mapuey" tubers in Venezuela are staple food for indigenous peoples from the Caribbean coast and Amazon regions. Noticeable differences between genotypes of yam starches were observed. Granules large, triangular, or shell-shaped with monomodal particle size distribution 24.5 35.5 μm. Differential scanning calorimetry (DSC) analyses revealed onset gelatinization temperatures 69.1 to 73.4 °C high enthalpy changes 22.4 25.3 J g−1. All X-ray diffractograms exhibit B-type crystallinity....
Only two mutations have been described in the literature, so far, regarding starch and root quality traits cassava. This article reports on an induced mutation this crop, first identified 2006. Botanical seed from five different cassava families were irradiated with γ rays. Seed was germinated, transplanted to field (M1 plants), self-pollinated produce M2 generation. Abnormal types granule morphology during single plant evaluation of genotypes. To confirm these characteristics, selected...
Abstract BACKGROUND: Orange‐fleshed sweetpotato (OFSP) can be used to tackle vitamin A deficiency, a major public health problem in most developing countries. In East Africa, common ways of using include drying and subsequent storage. The aim the study was investigate impact storage on total carotenoid retention (as an estimate provitamin retention) from OFSP. RESULTS: Losses during were generally low (15% or less). Total OFSP not dependent type dryer (solar sun). Sweetpotato cultivar...
Peach palm (Bactris gasipaes) is a multi-purpose tree native to tropical Latin America, which predominantly cultivated by smallholders in agroforestry systems. The fruits are rich starch and contribute importantly food security the cash income of farmers who cultivate them. Complex value chains have emerged that link producers consumers, but irregular product quality market chain inequalities undermine economic well-being retailers. genetically diverse, screening for traits commercial...
Portable Vis/NIRS are flexible tools for fast and unbiased analyses of constituents with minimal sample preparation. This study developed calibration models dry matter content (DMC) carotenoids in fresh cassava roots using a portable system. We examined the effects eight data pre-treatment combinations on assessed calibrations processed intact root samples. compared derived-DMC to other phenotyping methods. The results showed that combination standard normal variate de-trend (SNVD) first...
Cassava (Manihot esculenta, Crantz) is an important food security crop, but it becoming raw material for different industrial applications. the second most source of starch worldwide. Novel properties are interest to industry, and one them recently identified amylose-free (waxy) cassava starch. Waxy mutants have been found in crops often associated with a yield penalty. There ongoing efforts develop commercial varieties However, little information available regarding biological agronomic...
Abstract Within communities in Osun and Imo States of Nigeria, farmer–processors grew processed a diverse set improved landrace cassava varieties into the locally popular foods, gari , eba fufu . Local 15 main were grown ‘mother baby trials’ design each state. Mother trials with three replications by renown their community for processing skills. Baby managed other farmer–processors. The objective was to identify food quality criteria inform demand‐led breeding benefit users, especially...
Abstract Ontologies are widely used in databases to standardize data, improving data quality, integration, and ease of comparison. Within ontologies tailored diverse use cases, post-composing user-defined terms reconciles the demands for standardization on one hand flexibility other. In many instances Breedbase, a digital ecosystem plant breeding designed genomic selection, goal is capture phenotypic using highly curated rigorous crop ontologies, while adapting specific requirements breeders...
