A quantitative trait locus (QTL) controlling shoot differentiation from immature embryo callus was identified by linkage analysis with morphological and isozyme markers in barley, Hordeum vulgare L. Immature embryos were isolated from cvs ‘Azumamugi’ (difficult to differentiate), ‘Kanto Nakate Gold’ (easy to differentiate), their hybrids (F1) and a(More)
The locus Shd1, which we previously mapped to the long arm of chromosome 2 of Hordeum vulgare L., controls the differentiation of shoots from immature barley embryo callus. The locus has major effects and its action explains more than 65% of the total genetic variance in the shoot-differentiation rate. The allele of cultivar Kanto Nakate Gold designated(More)
INTRODUCTION Spatial coherency (or incoherency) of ground motion is important in the earthquake response analysis for mult-supported, buried and large-scale structures. However, the characteristics of the spatial coherency, especially that in short separation distance, are not fully investigated primarily because of the lack of the data. The loss of the(More)
