Table 1 Segregation of different traits of resistance against BPH and WBPH among RILs derived from the cross between TN1 X RP2068 observed in different phenotyping tests under greenhouse conditions

From: RNA-Sequencing Reveals Differentially Expressed Rice Genes Functionally Associated with Defense against BPH and WBPH in RILs Derived from a Cross between RP2068 and TN1

Test Number of RILs under group
RRa RS SR SS
Damage score (DS) in standard seedbox screening test (SSST) 9 16 28 127
Nymphal survival (%, NS) 8 22 33 117
Days to wilt (DW) 13 14 49 104
Nymphal preference at 24 h (%, NP24) 8 38 29 105
Nymphal preference at 48 h (%, NP48) 13 30 38 99
  1. Threshold values for R in DS: ≤ 3.0 (BPH), ≤ 4.0 (WBPH); NS ≤ 60.0%; DW ≥ 10.0; NP ≤ 10%
  2. aRR- resistant to both BPH & WBPH; RS- resistant to BPH only; SR- resistant to WBPH only; SS - susceptible to both BPH and WBPH
