Two new high yielding conventional soybean varieties 'Jake' and "Stoddard were developed and released by the Missouri Agricultural Experiment Station in January 2006. The name Jake is in honor of Jake Fisher, 45 year University of Missouri employee and current superintendent of the University of Missouri-Delta Center at Portageville, MO. Stoddard was named after Stoddard County. Both varieties have broad resistance to soybean cyst nematode (SCN) and resistance to root knot nematode. Jake also carries resistance to reniform nematodes. The have shown moderate resistance to stem canker, SDS and have good resistance to some races of frogeye leaf spot. They have shown moderate resistance to SCN HG type 2.5.7 (Race 1), HG type 1.2- (Race 2), HG type 0- (Race 3) and HG type 2- (Race 5) and HG type 1.3-(Race 14) in greenhouse tests. Broad resistance to SCN is derived from Hartwig via Anand one of the parents of each variety.

Jake is mid group V (relative maturity 5.4) with purple flowers, tawny pubescence and tan pods. Seed are shiny yellow with black hila averaging about 3100 seed per lb. Yield performance of Jake in five years of Delta Center tests averaged across 25 environments and in Regional uniform tests is shown in Table 1 below. Jake has averaged similar in yield on loam soils, but 8 Bu/A more on clay and sands compared to Anand which it is intended to replace. It has averaged four inches taller and one day earlier than Anand.

Stoddard soybean is early group V maturity (relative maturity 5.1) with white flowers tawny pubescence and tan pods. Seeds are shiny yellow with black hila averaging about 3200 seed per lb. Stoddard averages three inches shorter, similar maturity and slightly better lodging resistance than Manokin. Plants most closely resemble Anand in height, lodging and seed characteristics. Performance of Stoddard compared to Manokin in 25 southeast Missouri tests and in the regional uniform tests is shown in Table 2.
