摘　　要：通过表型选择和抗生性测定,已筛选出11个抗蓟马的苜蓿无性系,经过配合力测定,选出配合力高的无性系9个。通过试验还证明,采用一个冬春的温室与田问相结合的配合力试验,可以取代轮回选择中二年的配合力试验,缩短育种过程。Eleven thrips-resistant alfalfa clones are screened by phenotype selection and antibiosis appraisal. Nine of them are selected on the basis of high combining ability. The test has proved that two years, tests of combining ability in recurrent selection can be replaced by combining ability test i. e. using a green house in winter and spring, along with field trials. This method will shorten the breeding procedure.
