Abstract:Abstract:‘Guichicangteng No.1’and‘Guichicangteng No.2’are excellent strains of new medicinal and
edible vegetable varieties screened from the wild resources in Guangxi and bred mainly by rapid propagation via
tissue culture,supplemented by cutting propagation.The tender shoots of‘Guichicangteng No.1’are green
in color,with a yield of 28.5 t · hm-2.The tender shoots of‘Guichicangteng No.2’are red in color.Its flavor
is more rich than that of‘Guichicangteng No.1’.‘Guichicangteng No.2’can yield 25.5 t · hm-2.These 2
varieties all have axillary tendril and slender branches,on which there are indistinct stripes.The leaves change
from papery to thick papery or subleathery and were 8-20 cm in length,4-15 cm in width.The fresh tender
buds are about 15 cm in length with special flavor.The contents of protein,fat,coarse fiber,calcium,
phosphorus,VC and total amino acid content are higher than that of normal vegetables.Three years after field
planting,these 2 varieties will enter into a high-yielding period.They are suitable for open fields cultivation in
Guangxi and Southwestern areas,and protected cultivation in northern regions.
