Funded Projects
Existing KT Funded Research Projects:
The following research projects are either fully or partially funded by the Kirkhouse Trust. The Trust focuses its funding to projects on legumes in third world countries, particularly Africa and South Asia.African Bean Consortium (ABC), East Africa:
The Kirkhouse Trust's objective is the development of common bean (Phaseolus vulgaris) varieties through marker assisted breeding. The Trust supports plant breeders in East Africa to develop a marker assisted participatory breeding programme coordinated by Prof. Paul Gepts, University of California Davis.Integration of Marker-Assisted Selection into African Breeding Programs of Common Bean:
P.I. Prof. Paul Gepts:Project Start Date:01/08/2008
Project End Date: 31/07/2011
The 1x sequence of the gene space of the common bean genome is underway and should be obtained by October 2009. The UC Davis bioinformatics team are developing a database of bean markers. The University of Virginia (UVA) will collaborate with UC Davis by providing identifying markers shared between common bean and cowpea. Prof. Mike Timko is the lead scientist at UVA collaborating with the ABC programme.
The objectives of this project are to:
- develop a genomic survey sequence (1x) for the common bean genome (GSS);
- overlay bean and cowpea GSS, as well as Medicargo and Lotus sequences onto the physical map of common bean;
- develop and map additional micro-satellite markers from targeted BAC contigs, physical map BES, the bean GSS and bean-cowpea synteny areas, and;
- train African bean breeders in bioinformatics and laboratory procedures to develop and utilise new markers.

West African Cowpea Consortium (WACC) Research Projects:
In 2005 the Kirkhouse Trust decided to fund research on cowpea in West Africa. In 2006 a contract was signed to fund the research of the Cowpea Genomics Initiative at the University of Virginia. The West African Cowpea Consortium was formed when the first West African projects began in 2006.The main objective of the Consortium project is to develop improved cowpea varieties for West Africa, using marker-assisted selection (MAS). Sub-objectives are to:
- train African scientists in molecular genetic methods as applied to plant breeding for crop improvement;
- increase capacity in African laboratories and universities, through training of students preferably using legumes, with priority on cowpea;
- enhance trans-national collaboration between the African Institutions.
The WACC aim is to deliver cowpea varieties with a specific beneficial trait(s), manifested on farmers' fields as improved productivity under conditions which otherwise lead to loss in cowpea grain and/or fodder.

University of Agricultural Sciences, Bangalore, India (UAS, B):
The KT Funded Lab - P.I. Dr A. Mohan Rao:Project Start Date: 27/02/2002
Project End Date: 28/02/2010 (renewed yearly)
The Kirkhouse Trust set up and continues to fund a laboratory dedicated to plant molecular biology research at UAS, B. The facility is used by postgraduate students as well as by staff employed in projects funded by the Trust. Support for the laboratory is renewed on a yearly basis. Its overarching aim is to train postgraduate students in the application of molecular work and biotechnology in crop improvement. Students awarded research funding from the Trust gain priority access. The laboratory has also been used for a number of Trust-supported training courses in marker assisted selection and genetic transformation.
Dolichos (Lablab purpureus) - P.I. Dr M. Byre Gowda:
Project Start Date: 01/03/2006
Project End Date: 01/01/2014
The Trust continues to support a dolichos (Lablab purpureus) breeding programme focused on the development of determinate, photoperiod insensitive types, pioneered by the recent release of the variety "HA4". The release of a further two new lines is imminent. The Trust has recently approved a five year extension to continue the improvement of these genetic materials. In support of this activity, a seed storage facility has been constructed, and recent approval has also been given for the installation of a greenhouse. Associated with the breeding programme, the Trust has supported a PhD research programme aiming to develop a genetic map of dolichos (Lablab purpureus).
Pepper (Capsicum annuum L.) - P.I. Dr A. Mohan Rao:
Project Start Date: 01/03/2006
Project End Date: 01/12/2012
The initial project set out to expose the genetics of resistance to anthracnose in chilli pepper (Capsicum annuum L.). This fruit rot disease represents an important yield and quality constraint in Southern India, and natural resistance is rare. A major aim of this project was to develop molecular markers which could be exploited for the breeding of disease resistant varieties. Two sources of resistance; one present in a related species, and the other in a Thai landrace, have been identified. The work has been facilitated by a collaboration with the AVRDC in Taiwan (The World Vegetable Center), and has largely been carried out by a PhD student funded by the Trust. The project will likely be extended into a second phase soon.
Horsegram (Macrotyloma uniflorum (Lam.) Verdc.) - P.I. Dr K. P. Viswanatha:
Project Start Date: 01/07/2006
Project End Date: 27/02/2010
This project focused on the improvement of the orphan legume species horsegram (Macrotyloma uniflorum (Lam.) Verdc.) (referred to as the "poor man's pulse"). Its specific aim was to generate molecular markers for resistance to yellow mosaic virus. A combination of bulk segregant analysis with AFLP genotyping has recently allowed major progress towards this aim. The Trust has recently approved a one year extension, taking the project through until February 2010.
Moth Bean (Phaseolus acontifolia Jacq) - P.I. Dr S. Gangaprasad:
Project Start Date: 20/09/2007
Project End Date: 19/09/2010
Moth bean (Phaseolus acontifolia Jacq) is a rather under-utilised pulse crop, associated with an exceptional level of tolerance of infertile and / or drought-prone soils. The project set out to collect landrace material, evaluate it for key agronomic traits and assess its level of genetic diversity using molecular markers. The rationale of these studies was to identify promising parental combinations for the initiation of a breeding programme, which would apply marker technology, where possible, to improve its efficiency.
Sir M. Visvesvaraya Institute of Technology, Bangalore, India (SMVIT):
Velvet Bean (mucuna spp.) - P.I. Dr N. Sathyanarayana:Project Start Date: 25/02/2009
Project End Date: 25/05/2010
The Trust has recently approved a pilot research project at SMVIT. It aims to validate a spectrophotometric method of assessing the content of the naturally occurring non-standard amino acid 'L-Dopa' in the seed of velvet bean (mucuna spp.). Velvet bean (mucuna spp.) is a productive plant, but the presence of L-Dopa in its seed is a barrier to its exploitation as a food crop. If successful, the intention is to then apply the method to estimate the degree of genetic variability for L-Dopa content among accessions of velvet bean (mucuna spp.), and if relevant, to understand the genetic basis of such variation. This information will facilitate a rational decision as to whether to invest in the initiation of a breeding programme aimed at generating varieties of velvet bean (mucuna spp.) suitable for the human food chain.
