Orychophragmus violaceus O.E. Schulz is a member of Brassicaceae. This plant
is mainly distributed in China, where a number of people collect its flower
stalks from the wild as a traditional vegetable. The purpose of the present
study is to obtain more information about this new germplasm and to exploit
it in breeding of horticultural brassicas. The test material used were O. Violaceus
and a Brassica campestris var. purpuraria L.H. Bailey as a control. The experimental
methods include domestication, cultivation, nutrient analysis and evaluation
of comprehensive nutritive value. The main results are as follows: 1) The result
of domestication shows that the wild species O. violaceus can be domesticated.
It has numerous branches, from which flower stalks with your flower buds can
be collected as a vegetable; 2) When O. violaceus was sown in September in Chengdu,
it had a yield of flower stalks about 14,200 kg/hectare, which was a good yield.
Yield can be improved when appropriate agronomic techniques are applied; 3)
The comprehensive nutritive value of O. violaceus is higher than other members
of Brassicaceae with the highest content of protein and higher contents than
most of the others of fat, calcium, iron, carotene and vitamin. Therefore, it
is suggested that O. violaceus is a potential new vegetable which can be exploited
in breeding of horticultural brassicas.
