Abstract:	The soyabean (Glycine max) germplasm line G93-9009 (PI591825), originating as a F4-derived line from the cross G83-559 √ó (G80-1515*2 √ó PI96354) and released in 1995, has a similar level of resistance to southern root-knot nematode (Meloidogyne incognita (Mi)) as PI96354, which has the highest level of resistance identified in soyabean to date, but higher seed yields. In yield trials conducted near Athens and Plains, Georgia in 1993 and 1994, G93-9009 outyielded PI96354 by 83% and was within 1% of the yield of Bryan. In 2 greenhouse experiments, G93-9009 and PI96354 each averaged 4 Mi galls/plant, compared with 16 galls/plant for Bryan and 164 galls/plant for the susceptible control Bossier. G93-9009 is a maturity group VI germplasm that matures about 4 days earlier than Bryan and 4 days later then PI96354. It is 14 cm shorter and has better lodging resistance than Bryan. G93-9009 is also resistant to M. arenaria, M. javanica, Heterodera glycines races 3 and 14, and Xanthomonas campestris pv. glycines.
