A Study of Ecological and Morphological Characters on Tibet Zebu as a New Genetic Resource
摘要
Abstract
Arpijaza, Lekezhi and Zhangmu cattle discovered in cooled region of Tibet are Bos populationswhich have close blood relationship with zebu. Besides studying their distribution, nature environment and ec-ological conditions, the multivariate statistics analysis of three sides (i. e. , body measurement, morphologyand ecology characters)were carried out on three zebu populations from cooled region of Tibet and other threereference populations. The results indicated that there were various ecology types within Tibet zebu popula-tions. Fore two character values were selected as the principal components (occupied 88.15% of total informa-tion amount). The cluster analysis according to two principal component values of each sample displayed thatthree zebu populations from Tibet and two zebu populations from Yunnan emerged in clustering figure alter-nately, Lhasa yellow cattle was independent from the five zebu populations. The study has proved that therewere zebu populations in Tibet cooled region and there was a possibility of blood relationship between the zebupopulations from Tibet and Yunnan.关键词
