Understanding the distribution of genetic diversity within and among individuals, populations, species and gene pools is crucial for the efficient management of germplasm collections. Molecular markers are playing an increasing role in germplasm characterization, yet their broad application is li...

Monneveux, P.Ortiz, O.[Is crop breeding the first step to fill the yield gap? Understanding the impact and constraints of developing new improved varieties.]Is crop breeding the first step to fill the yield gap? Understanding the impact and constraints of developing new improved varieties.

Conventional plant breeding largely depends on phenotypic selection and breeder's experience, therefore the breeding efficiency is low and the predictions are inaccurate. Along with the fast development in molecular biology and biotechnology, a large amount of biological data is available for gen...

Cassava is a tropical storage-root crop that serves as a worldwide source of staple food for over 800 million people. Flowering is one of the most important breeding challenges in cassava because in most lines flowering is late and non-synchronized, and flower production is sparse. The FLOWERING ...

Presents findings of a study carried out to determine differences between 24 sorghum varieties in digestibility of leaf and stem components and yield of stover. Emphasis is given to encourrage breeds involved in slelecting sorghum varieties for use on small farms where sorghum stover is an import...

Cassava mosaic begomoviruses (CMBs) cause cassava mosaic disease (CMD) across Africa and the Indian subcontinent. Like all members of the geminivirus family, CMBs have small, circular single-stranded DNA genomes. We report here the discovery of two novel DNA sequences, designated SEGS-1 and SEGS-...

A brief reference is made to new bean germplasm accessions and breeding lines identified at CIAT with specific architectural traits. Examples are given for type I bush beans with 10 or more nodes on the main stem, erect branching, suppressed branching, short foliage and internodes, lanceolate lea...
