[Mapping QTLs controlling vascular bundle and panicle-related traits from Yuanjiang common wild rice (Oryza rufipogon Griff.)].
Yi Chuan Xue Bao = Acta Genetica Sinica 2005 Februrary
An advanced backcross population (BC3F2), derived from the cross between Yuanjiang common wild rice as the donor parent and Teqing as recurrent parent, was used to map QTLs controlling the number of vascular bundle and panicle-related traits from Yuanjiang common wild rice. Seven QTLs controlling the number of large vascular bundles in peduncle were detected on chromosome 1, 2, 3, 4, 7 and 10. Five QTLs for the number of small vascular bundles in peduncle were mapped on chromosome 1, 2, 3, 4 and 8. A total of 15 QTLs for the number of primary and secondary rachis branches and spikelets per panicle were identified on all chromosomes except chromosome 11 and 12. Most of alleles derived from O. rufipogon Griff. showed negative effect that reduced significantly vascular bundle, rachis branches and spikelets per panicle, suggesting that during the evolution from common wild rice to cultivated rice, favorable alleles were retained while removed undesirable ones. Most of QTLs controlling vascular bundle, rachis branches and spikelets per panicle showed cluster form or close linkage on chromosomes. The directions of their additive effects were consistent, which explained the genetic basis of significant correlation of their phenotypic characters. All the information suggested parallel evolution relationship among these traits.
