Genetic distance as a predictor of heterosis in single cross hybrids of fodder maize (Zea mays L.)
Assessment of genetic distance between parents and selection of diverse parents are extensively used in many crops. Current study focuses the importance of genetic distance assessed through SSR markers (GDMOL) and morphological traits (GDMOR) in 28 fodder maize inbred lines and its impact on heter...

| description | Assessment of genetic distance between parents and selection of diverse parents are extensively used in many crops.
Current study focuses the importance of genetic distance assessed through SSR markers (GDMOL) and morphological
traits (GDMOR) in 28 fodder maize inbred lines and its impact on heterotic expression in resultant 195 single cross fodder
maize hybrids. While comparing the mean green fodder yield in top performing hybrids synthesised with parents of
higher GDMOL and GDMOR, it is understood that the genetic distance had definite impact on yielding heterotic hybrids
with superior green fodder yield. It is evident from identification of a single cross UMI 1200 X GETM 25 with parents of
greater GDMOL and GDMOR and a cross N 66 X DM 12-4 with parents of higher GDMOR recorded greater green fodder yield
and superior standard heterosis (20.88%). The correlation studies revealed significant positive association between
higher GDMOL of parents and heterotic performance of hybrids for crude protein and desirable negative association with
crude fibre, ADF and NDF. |
