| Abstract | ||
| To produce pyrethrum economically, high yielding varieties and clones should be produced. Therefore, pyrethrum - breeding program was started since 1993 following clonal selection method including four steps (single plant selection,single line selection,screening trial and replicated yield trial). By starting with 2000 plants , only six clones of high content and production of total pyrethnns were selected and concerned as better clones for both growers and researchers. In this experiment it was found that pyrethrins content in clones SE 6 , 15 , S»h 77, si and SE 87 were 1.806,1.856, 1.532, 1.890 and 2.205%, respectively. Due to high pyrethrins yield in clone SE 134, this clone was also selected.* | ||
