Heterosis in Quality Protein Maize

Anusheela. V, A. R. Muthiah, A. Johnjoel

Abstract :

With an objective to identify potential parents and hyids for quality and other traits for maize improvement, an investigation was carried out with Line x Tester analysis involving five lines (UQPM 5,UQPM 11, UQPM 12, UQPM 13, UQPM 15) and three testers (UQPM 9, UQPM 10,UQPM 14) . Eight parents and their fifteen hyids obtained from crosses were evaluated for twelve quantitative traits viz., days to silking, plant height, ear height, number of leaves per plant, leaf length, leaf eadth, cob length, number of grain rows per cob, hundred grain weight, grain length, grain eadth, grain width and grain yield per plant and three qualitative traits namely grain protein, grain tryptophan, and grain lysine. In the Line x Tester analysis, significant variability was observed among the genotypes for fifteen traits. Four hyids viz., UQPM 13 X UQPM 14, UQPM 5 X UQPM 9, UQPM 15 X UQPM 10 and UQPM 12 X UQPM 10 were observed to be potential hyids for exploitation of yield heterosis and utilizing them in pedigree eeding will also result in potential ineds.
