Selection individual on mutant genotype of soybean (Glycine maxl.merrill) in m₅ generation based on resistance of stem rot disease Athelia rolfsii (curzi)

This study was aimed to obtain selected individuals on soybean plant Glycine max L. (Merrill) in M5 generation based on high production character and tolerance of stem rot disease Athelia rolfsii (Curzi). This research was conducted in Plant Disease Laboratory and experimental field Faculty of Agriculture Universitas Sumatera Utara Medan, Indonesia. This research was conducted from December 2016 to June 2017. The treatments were 15 mutant lines genotypes and Anjasmoro variety. The results showed that some lines mutant genotypes can gave the good agronomic appearance character than Anjasmoro variety on inoculation treatment of stem rot disease. Selection performed on population M₅ producesselected individuals with tolerance of stem rot disease from 100 and 200 Gy population.
