• Marker work restricted to only assessment of diversity<br />
• These studies have <strong>in</strong>dicated very low genetic diversity <strong>in</strong> the world collection<br />
- monotypic species – so only primary gene pool to be exploited<br />
• So far ma<strong>in</strong>ly anonymous markers have been used for diversity study<br />
• We have developed 519 class I EST-SSR primers and they are be<strong>in</strong>g used<br />
<strong>in</strong> tagg<strong>in</strong>g wilt resistance gene(s)<br />
• Recently complete genome sequence published<br />
(Nature Biotech., August 22, 2010)<br />
Immediate target traits – reduced ric<strong>in</strong> and RCA content – complex genomics<br />
- Botrytis tolerance (devastat<strong>in</strong>g disease with 80% loss)<br />
- sex expression problem<br />
- heterotic pools for <strong>in</strong>creased yields
