use it as a symbol :organelle rather than as a string “organelle”  
make sure the :organelle field is made available in ur model seqfeature

change like

\<%= form.select :organelle, (["",  
“mitochondrion”, “nucleomorph”, “plastid”, “mitochondrion:  
kinetoplast”,  
“plastid: chloroplast”, “plastid: apicoplast”, “plastid:  
chromoplast”,  
“plastid: cyanelle”, “plastid: leucoplast”, “plastid:  
protoplastid” ])  
%\>

```
 and it will submit to the create action of seqfeature controller. 

```

.There you can write the code as in def view
