摘　　要： 对44个水稻品种(品系)进行花药培养试验,结果表明,1粳稻品种(品系)的平均出愈率和最高出愈率均大于籼稻,在2个亚种中都存在出愈率高和低的品种(品系);2在粳稻和籼稻中都存在分化率高和低的品种(品系),籼稻和粳稻的平均分化率差异不大;3水稻品种(品系)的花药培养出愈率普遍低于分化率,出愈率低是大部分品种(品系)培养力低下的主要原因;4出愈率与分化率无相关。 The callus induction rate and shoot differentiation rate of 44 rice cultivars were observed. The results showed that:①The cultivars with high or low callus induction rate were found from anther culture in both indica and japonica subspecies, and the average and the highest value of callus induction rate of indica cultivars were higher than those of japonica cultivars; ②The cultivars with high and low shoot differentiation rate were found in both subspecies, and the average value of shoot differentiation rate in indica and japonica was similar;③The callus induction rate was lower than shoot differentiation rate, and the poor anther culture ability in most rice cultivars was mainly due to their low callus induction ability;④There was no correlation between the callus induction rate and shoot differentiation rate in rice anther culture.
