| dc.description | Several genetic regions having major effects on maturity have been identified using RFLP analysis. One such region on chromosomes 8 is important across several diverse genotypes and ccounts for up to 50% of the variation for maturity in a cross involving an inbred line (N28) and a 20-backcross generation derivative (N28E). In addition to the chromsome 8 QTL for maturity, we have evidence using the backcross-derived line approach for regions controlling maturity on chromosomes 1, 2, 3, 5, 7, and 9. Chromosome 5 appears to be especially important in both magnitude of effect and across several genetic hackground. Maturity as measured by days to pollen shed or silking may be controlled by additive or nearly dominant gene action depending on the chromosome region. The marker-trait linkages were consistent across environnments based on A662 X B73 F3 per se and testcross evaluations from three locations in one year. UMC12 (chromosome 8) and UMC54 (chromosome 5) also marked important regions for maturity in these materials. | |
