Table 1 Mean squares from ANOVA and correlation coefficients for KRN, KNPR, and HKW

From: A non-synonymous SNP within the isopentenyl transferase 2 locus is associated with kernel weight in Chinese maize inbreds (Zea mays L.)

  1. DF degrees of freedom, HKW hundred kernel weight, KRN kernel row number, KNPR kernel number per row, h2 broad-sense heritability; **, P <0.01; *, P <0.05.
  2. a Because the phenotypic values for some lines were missing for kernel weight, the DF differ. The numbers in parentheses indicate the DF for HKW and the numbers outside parentheses indicate the DF for KRN and KNPR.
