Abstract


Domesticated maize is the consequence of diminished variability and genetic erosion, while wild teosinte is the opulent source of genetic variation in some of the desirable agronomic and kernel traits which are meant to be exploited in maize more through the wide hybridisation to boost up its germplasm amelioration. Very unlikely numbers of researches have been carried on improvement of predomestication alleles. To exploit the variation for some of the novel traits, the teosinte introgressed maize F1 hybrids were analysed for the variability parameters, existing variance and association analysis in this paper. Traits namely number of tillers and main stalk, number of brace roots, plant height, kernel weight, FFD, and kernel area showed high variability which can be used further in useful selection for maize improvement. Simple correlation analysis was analysed for the traits which shows significant positive association of 1000-kernel weight with the other kernel traits. The experiment thus emphasizes the identification and improvement of more desirable predomestication alleles towards the direction of diversity in maize germplasm.
