After establishing the trials, they need to be managed to ensure the required data quality. The management of trials includes a series of agronomic activities ranging from gap...

Land preparation and planting are very important in the successful establishment of a trial. A poorly prepared land can affect seed germination, increase weed pressure, increase...

Semi-Autotrophic Hydroponics (SAH) is a robust technique for efficiently and rapidly multiplying clonally propagated crops. It is a low-cost and licensed method for high ratio...

Site selection and field plot layout are important components of experimentations and require adequate attention. Poor site selections and field layouts are major sources of...

This document lists the different tasks to be performed by the use case team before and during the enumerators’ training to ensure digital data collection in the field is smooth.

Accurate data collection is essential for precise decisions in yam breeding activities. It is relevant for reliable choices in selecting and advancing desirable genotypes.

The yam breeding generates thousands of genotypic and phenotypic data every year from genetic studies and breeding trials. There is a need for data centralization, curation,...

Yam (Dioscorea species) leaf samples contain high levels of polysaccharides and polyphenolic compounds. The extraction of DNA from leaves is usually problematic. Therefore,...

The tuber is the food organ and the essential part of the yam plant. Evaluations and selection are premised on this economic part, just like in other root ad tuber crops. The...

Yam trial management involves all the activities implemented throughout the life cycle of a yam trial/experiment, either in the field, screenhouse and laboratory, following a...

The yam breeding program executes regional varietal trials (RVTs) in collaboration with its national partners in different countries. The objective of the trial is to...

Barcode labels are used for trials plot, genotypes identification and tracking purposes. For the labelling of a trial, this includes stages of advancement, the location of the...

Hybridization in yam is a process of transferring of male pollens to female flowers to generate viable seeds with desired genetic recombination of the parents. Hybridization...

Seedling nursery involves the raising and management of seedlings from botanical seeds for the purpose of progeny or population development. This is a major stage that succeeds...

The design of experiments and how it is established have significant impact on the quality of data and the decisions made based on such data thereof. Properly designed...

Harvesting is another key activity in the cowpea breeding program that requires much attention. This is the stage where varietal seed mixing can occur. Timely harvesting is...

Data capturing is a key component of any trial, given that it drives the decisions in the breeding programs. Without good data, the main purpose for which the trial is...

Genotyping is the process of determining differences in the genetic make-up (genotype) of an individual by examining the individual's DNA sequence using biological assays and...

Sesamia calamistis Hmps. and Eldana sacharina Walker are two of the most important stem borers of maize in Africa (Bosque-Perez et al... these proceedings). Resistant varieties...

Seed packaging processes in any breeding program is very important. Seed packaging procedures are fundamental to the long-term, cost effective and efficient conservation of...
