Recurrent selection for intrapopulation improvement and cultivar development in maize (Zea mays L.) - An analysis

Published on

Recurrent selection is widely used in maize (Zea mays
L) breeding. Extensive studies have been carried out on
recurrent selection for intrapopulation improvement in elite
populations by the Indian maize breeders. In the present
study, the results of some experiments conducted at the
Punjab Agricultural University, Ludhiana, have been
analysed with respect to improvement in the elite
per se and development of open-pollinated
(OP) cultivars. The analysis indicates that, though,
recurrent selection has been effective in enhancing the
performance of elite populations
per se, recurrent selection
accompanied by germplasm introgression in elite
population has been more successful in OP cultivar
development. It suggests that step-wise intervarietal
hybridization accompanied by recurrent selection for
intrapopulation improvement may be a better approach
than recurrent selection within populations without
germplasm introgression, for the development of OP
