Sedimentation Value

Phenotypic correlations among five quality traits and five agronomic traits were calculated for three groups of 110 lines of a spring wheat cross (Triticum aestivum L.) grown in a total of four years in central Alberta. All correlations among pairs of traits were homogeneous from year to year with the exception of four involving maturity, yield, height and grain nitrogen content. The large negative correlation between nitrogen content and yield was judged detrimental to the prospects of simultaneous improvement of both traits. Maturity, height, kernel weight and yield were all positively interrelated. Large negative correlations were observed between sedimentation, value and tolerance index and between nitrogen content and starch damage. Sedimentation value and dough development time exhibited a strong positive relationship. The mean value for lines fell within the range of the parents in all cases except for sedimentation value and height.

Several linkage maps, mainly based on anonymous markers, are now available for Lolium perenne . The saturation of these maps with markers derived from expressed sequences would provide information useful for QTL mapping and map alignment. Therefore, we initiated a study to develop and map DNA markers in genes related to self-incompatibility, disease resistance, and quality traits such as digestibility and sugar content in two L. perenne families. In total, 483 and 504 primer pairs were designed and used to screen the ILGI and CLO-DvP mapping populations, respectively, for length polymorphisms. Finally, we were able to map 67 EST markers in at least one mapping population. Several of these markers coincide with previously reported QTL regions for the traits considered or are located in the neighbourhood of the self-incompatibility loci, S and Z. The markers developed expand the set of gene-derived markers available for genetic mapping in ryegrasses.
