QTL mapping of vegetative characters in wheat (Triticum aestivum L.)

摘要

A set of 114 recombinant inbred lines (RILs) of the ITMI mapping population was grown under greenhouse conditions in Gatersleben. The lines were evaluated for the vegetative characters early growth habit, basal culm colour, leaf arrangement, length and width of different leaves, shape of the ligule, presence and absence of an auricle, plant height and waxiness. For the character basal culm colour a major QTL could be detected on chromosome 7AS. This corresponds with a known QTL for coleoptile anthocyanin colour but not with the QTLs for the colour of the upper part of the culm. A major QTL could be confirmed for early growth habit on chromosome 2DS. For the characters leaf arrangement, length and width of different leaves, ligule, and auricle no distinct major QTLs could be found. However, for plant height and waxiness major QTLs were determined on chromosomes 3BS, 5AL and on chromosome 2DS, respectively.
