Abstract
L62-904 has resistance (Table 1) to some races of Phytophthora megasperma var . sojae (Pms) . L62-904 was developed by Dr. R. L. Bernard at Urbana from Harosoy6 x T240; it was an F2 selection from an F1 - BC5 plant that was Ps ps W1 w1. It was used at Harrow as a w1w1 'Harosoy' isoline with white flowers/green hypocotyls as a genetic marker in crosses before it was discovered to have Pms resistance.
