Growth cycle acceleration in bean breeding
This project aims at studying different treatment which induce rapid flowering and development of a single pod and compare different treatments in greenhouse trials.
Common bean (Phaseolus vulgaris L.) is the most important grain legume and protein source for human
consumption worldwide. Beans are of particular importance for nutrition and income of smallholder farmers in the
tropics. Climbing beans, a distinct subgroup of common beans, are reported to have significantly higher yields, produce more vegetative biomass, and have positive effects on soil fertility compared to bush types. The International Center for Tropical Agriculture (CIAT) in collaboration with the ETH started breeding activities in this
neglected climbing type. Faster growth cycle is desired to accelerate the development of new breeding lines. It can be combined with genomic selection strategies, which select suitable parents for a cross based on marker data.
Successful implementation of growth cycle acceleration will allow to double the number of generations per year from two to four and will speed up breeding.

In this project, we would like to extend our knowledge to treatments which induce rapid flowering and development of a single pod and compare different treatments in greenhouse trials

This project will be carried out at the CIAT headquarter in Cali, Colombia. It aims to
develop a protocol for fast generation advance in climbing beans. Stress conditions (drought, removing the apex) and chemical treatments (hormones) will be carried out to induce rapid flowering. Greenhouse trials will determine the earliest stage at
which seeds can be harvested.
