Table 1 Segregation ratio of spikelet fertility (SS) in the tested 225 lines

From: Identification of QTL Combinations that Cause Spikelet Sterility in Rice Derived from Interspecific Crosses

Reference point (RF) Seg No. of plants X2 value
Fertile Moderate Sterile Total 1:2:1 9:3:4
RF-I F:M:S 130 52 43 225 132.4** 5.49ns
RF-II F:M:S 130 31 65 225 156.4** 4.97ns
RF-III F:M:S 130 20 75 225 179.0** 18.01**
  1. Seg.: segregation of spikelet fertile classified into three classes: F (Fertile), S (Sterile), and M (Moderate fertile) according to reference point (RP) distinguish fertility from sterility. RF-I (F: M: S = over 85%: 85–45%: less than 45%), RF-II (F: M: S = 85: 85–55: 55), RF-III (F: M: S = 85: 85–65: 65)
  2. nsNot significant
  3. Significant levels: *P < 0.05 and **P < 0.001
