Roots, tubers and cooking bananas are bulky and highly perishable. In Africa, except for yams, their consumption is mainly after transport, peeling and cooking in the form of boiled pieces or dough, a few days after harvest. To stabilize, better preserve the products and, in the case of cassava, release toxic cyanogenic glucosides, a range of intermediate products have been developed, mainly for cassava, related to fermentation and drying after numerous processing operations. This review highlights, for the first time, the impact of genotypes on labour requirements, productivity, and the associated drudgery in processing operations primarily carried out by women processors. Peeling, soaking/grinding/fermentation, dewatering, sieving, and toasting steps were evaluated on a wide range of new hybrids and traditional landraces. The review highlights case studies of gari production from cassava. Results show that, depending on the genotypes used, women's required labour can be more than doubled and even the sum of the weights transported along the process can be up to four times higher for the same quantity of end product. Productivity and loads carried between each processing operation are highly influenced by root shape, ease of peeling, dry matter content and/or fiber content. Productivity and the often related experienced drudgery are key factors to be considered for a better acceptance of new genotypes by actors in the value‐addition chain, leading to enhanced adoption, and ultimately to improved livelihoods for women processors.This article is protected by copyright.

A total of 61 superior genotypes which included germplasm collections and prebreeding lines of sweet potato maintained in NAGS at ICAR-CTCRI and the popular released variety Sree Arun as control were evaluated in this study for six seasons for finding out the stable performer over the seasons. The best performers in each season were continued in the following seasons along with new genotypes for evaluation for six seasons. The observed variable was the yield (kg per plant). Data analysis was performed on yield character (kg per plant) by using SAS 9.1.3 (SAS Institute, Cary, North Carolina, USA), and means were separated by the least significant difference (LSD) at (p ≤ 0.01). The dry matter, starch, sugar, fibre and ash were estimated in the selected accessions. The genetic merit of each genotype was evaluated by best linear unbiased prediction (BLUP) using restricted maximum likelihood (REML) for variance component estimation in R. The overall mean across locations and years for tuber yield showed that 526/7 (S-1609) as the best accession, followed by S-1401. A similar ranking of varieties was observed for tuber yield using BLUPs. Amongst the tested samples, two (526/7 and S-1401) were found to be superior as compared to the rest of samples in terms of sensory evaluation criteria especially consistency, texture and sweetness and overall taste.
