Table 2 Segregation analysis of resistance to P. sojae PNJ4 in F8:11 (Guizao1 × BRSMG68)

From: Fine mapping of a Phytophthora-resistance locus RpsGZ in soybean using genotyping-by-sequencing

Cross or Parenta Total no. of plants/lines Expected ratio and goodness of fit
Resistance Susceptibility Expected ratio X2 P
BRSMG68 0 180    
Guizao1 180 0    
F8:11(Guizao1 × BRSMG68) 113 115 1:1 0.004 0.95
  1. (a) BRSMG68 was PRR-susceptible cultivars to PNJ4 strain, and Guizao1 was PRR-resistant to PNJ4 strain
