Özet
Maize grain yield is a complicated character which depends on multiple factors. Considering thisaspect, we carried out an experiment to estimate the genetic parameters and character association ofthirty inbred line in maize during November 2017 to April 2018. The highest genotypic coefficientof variation (GCV) was observed for a Number of kernel row per ear (NKRE), ear diameter (ED),plant height (PH), number of kernels per row (NKR). However, heritability (percentage) exhibitedhighest for the yield per plant (YP), thousands kernel weight (TKW), cob weight (CW), first earheight (FEH), ear length (EL). The percentage of genetic advance (GAM%) was high for YP, CW,PH, FEH, TKW. Results demonstrated that EL has a significant positive correlation with NKR (r =0.661**). YP showed significant positive correlation with PH (r = 0.718**). While EL (r = 0.587**),NKR (r = 0.501**), NKE (r = 0.422**), and TKW (r = 0.612**) showed insignificant associationwith YP (0.718). YP has insignificant association with EL to NKRE (r = -0.0414) and PH to FEH (r= -0.092). Highest and positive direct effect on YP was exhibited by TKW (0.519). Considering alltraits, IL-28, performed better followed by IL-9, IL-15, and IL-10. The development of hybridsgenotypes, these genotypes have the chance to obtain higher heterosis with high performing crosses.
