Abstract:
Records and breeding reports of registered soybean cultivars from 1923 to 2007 in Jilin Province were analyzed.Total 323 soybean cultivars have been bred during the past 85 years in Jilin and the number of released cultivars has been increased along with the time.Total 125 soybean cultivars have been bred since 2000.Average yield of regional test cultivars increased from 1549.7 kg.hm-2before 1950s to 2777.8 kg.hm-2 after 2000.Yield increasing respectively reached 45.2%，5.2%，5.0%，4.5% and 15.3% during 1960s，1970s，1980s，1990s and after 2000.Forty-five soybean cultivars with oil content higher than 22% were bred and oil content of Jiyu 89 reached 24.61%.Twelve soybean cultivars with protein content higher than 45% were bred and protein content of Jiyu 101 reached 47.94%.Contributions to breeding in different years showed that breeding progress had been the largest since 2000.
