Cold-resistance evaluation in 25 wild grape species
A cold-resistance analysis of 64 accessions of 18 wild Chinese Vitis species and 9 accessions of 7 wild American Vitis species was carried out to give a cold index, relative conductivity, soluble sugars, soluble protein, malondialdehyde and proline of one-year-old shoots under appropriate freezing treatments. Subordinate function analysis results indicate that there are substantial differences in cold resistance among the various germplasms. Among the eighteen wild Vitis species native to China, the cold-resistance rankings (high to low) are: V. amurensis, V. yeshanensis, V. adstricta, V. pseudoreticulata, V. quinquangularis, V. piasezkii, V. hancockii, V. ficifolia, V. romanetii, V. davidii, V. piasezkii var. pagnucii, V. bashantica, V. liubaensis, V. qinlingensis, V. davidii var. cyanocarpa, V. wilsonae, V. baihensis, and V. davidii var. ninqiangensis. Among the seven wild Vitis species native to America, cold-resistance rankings are: V. riparia, V. arizonica, V. rupestris, V. rotundifolia and V. californica (all high resistance) and V. labrusca and aV. cinerea (medium resistance). The most cold-resistant accession is V. riparia Mcadams. These results will be valuable for the selection of wild grape species for coldresistance breeding.
