Anthocyanin Expression Standard 1-67

Sold in packs of 100 seeds.

Plants of 1-67 have strong expression of purple pigment (anthocyanin) on the hypocotyl, cotyledons, stems, leaves, hydathodes, sepal tips and anther spots. Pan (8).  Seed color is brown with the exception of a low percentage (less than 10%) of seeds which have yellow seed coats, Ysc2. Yellow seed coat, Ysc2, in stock 1-067, is conditioned by a few genes (oligogenic), none of which are allelic to anthocyaninless, anl. 

The intensity of Pan expression is high, Pan (9), and is increased by light, nutrient and water stress, low temperature and other environmental factors. Pan appears to be quantitatively inherited and may be quantified by scaling, using a color comparator scale, Pan (0-9). There appear to be major genes or loci that influence the intensity and location of Pan expression, e.g. on the cotyledons, hydathodes, sepal tips and style.

Plants of stock 1-067 have been selected to have numerous hairs on stems and leaves. Hir is quantitatively inherited and may be determined by scaling Hir (0-9) or direct count. Hairs on leaf margins can be easily counted.

This stock was selected and bred from 1-33 with selective crosses to high anthocyanin expressing Brassica rapa vegetables to increase the anthocyanin expression.
