From: Improvement of rice blast resistance by developing monogenic lines, two-gene pyramids and three-gene pyramid through MAS

  Pita homozygous Pita heterozygous pita homozygous Total Segregation ratio for Pita Segregation ratio for Pi2
Pi2 homozygous 12a 26 14b 52
Pi2 heterozygous 28 56 21 105
pi2 homozygous 15c 32 13 60
Total 55 114 48 217 55:114:48 52:105:60
χ 2 1.01 0.82
  1. Note: a, b and c mean that the plants carried two R genes (Pi2 + Pita), one R gene (Pi2) and one R gene (Pita), respectively; χ2(0.05, 2) = 5.99.
