Background,
,
The,navy,bean,(Phaseolus)vulgaris,L.),is,an,important,ingredient,of,the,
BriVsh,diet,,with,many,people,in,the,UK,relying,on,baked,beans,as,a,part,
of,their,fiveWaWday,nutriVon.,,
,
All,of,the,baked,beans,we,eat,in,Britain,(~1.7,million,cans,per,day),are,
imported,,primarily,from,Canada,(Fig.%1).,
,
The,navy,bean,is,a,potenVally,viable,rotaVonal,crop,for,UK,farmers,,
however,,and,homeWgrown,beans,could,appeal,to,people,in,Britain.,,
,
In,addiVon,to,the,potenVal,market,value,of,locally,produced,navy,beans,,
growers,could,make,agronomic,gains,from,incorporaVng,a,leguminous,
break,crop,into,their,rotaVons,,which,could,promote,soil,renewal,a[er,
repeated,cereal,and,oilseed,rape,rotaVons.,,

This,research,revives,heritage,navy,bean,lines,developed,
for,UK,condiVons,by,crop,scienVsts,at,the,NaVonal,
Vegetable,Research,StaVon,in,Wellesbourne,in,the,1980s.,,

It,involves,applying,modern,DNA,sequencing,technology,
to,begin,mapping,genes,governing,the,traits,required,by,
a,variety,for,UK,farmers,to,grow,navy,beans,successfully.,

The,project,involves,developing,a,database,of,geneVc,markers,that,are,

,
It,is,anVcipated,that,these,markers,–,some,of,which,will,act,as,signposts,
for,the,genes,(alleles),of,interest,–,will,improve,the,ability,of,breeders,to,
select,varieVes,combining,these,traits.,This,could,help,to,redress,the,
