18世纪时，用牛头犬与梗类配种产生叫"bull and terrier"的牛头梗斗犬，后来与英国的玩具梗和惠比特犬品种，产生出具凶猛性，快速敏捷的犬种来。1860年，犬商詹姆士喜克斯将此犬加上英国猎梗，大麦町犬，西班牙波音达的品种，经过多次品种改良后，产生了现在的白色，平脸，强壮，四肢比祖先短小的牛头梗。1920年，因为白色品种遗传了听觉上的缺陷，被毛被加上了其他颜色。19世纪，白色牛头梗在热爱斗牛犬的人中间深受好评。

From differentiation of soybean varieties and photoperiod adjustment, anatomical differentiation essence of different types of stem termination soybean varieties, variation law of stem termination development under different photoperiod treatments, effect of long day on the terminal raceme of soybean, regulation rules of AGAMOUS gene among different soybean varieties and under different photoperiod treatments were studied, which would provide theory base of plant type breeding of soybean especially improvement of podding-habits and cultivation and management of soybean.
