Safflower (Carthamus tinctorious L.) is an oilseed crop that is valued as a source of high quality vegetable oil. The genetic diversity of 16 safflower genotypes originated from different geographical regions of Iran and some with exotic origin were evaluated. Eight different seed quality-related traits including fatty acid composition of seed oil (stearic acid, palmitic acid, oleic acid and li...

castor (ricinus communis l.) is one of the most ancient medicinal oil crops in the world. it has been vastly distributed in different parts of iran. in the present study, the inter simple sequence repeat (issr) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of iran. totally, 16 issr primers amplified 166 loci, of whic...

—Sceptridium dissectum, the most variable North American grapefern species, demonstrates variation in degree of blade dissection, blade color, pinnule shape, and pinnule margins. Historically, various morphologies have been included within S. dissectum. For example, Clausen’s monograph recognized five infraspecific taxa in S. dissectum, of which only the morphologies of variety dissectum and ob...
