The Ppd-A1 genotype of 240 Japanese wheat cultivars and 40 foreign cultivars was determined using a PCR-based method. Among Japanese cultivars, only 12 cultivars, all of which were Hokkaido winter wheat, carried the Ppd-A1a allele, while this allele was not found in Hokkaido spring wheat cultivars or Tohoku-Kyushu cultivars. Cultivars with a(More)
Changes in peak time and amplitude of the direct current registered c-wave of the electroretinogram of the albino rabbit were investigated with various stimuli of duration ranging from 0.25 to 10 sec. The stimulus intensity was 500 lux at the surface of the cornea. Slow PIII was isolated by administrations of sodium iodate and sodium aspartate. The peak(More)
The winter wheat variety Kitahonami shows a superior flour yield in comparison to other Japanese soft wheat varieties. To map the quantitative trait loci (QTL) associated with this trait, association mapping was performed using a panel of lines from Kitahonami's pedigree, along with leading Japanese varieties and advanced breeding lines. Using a mixed(More)
Wheat yellow mosaic virus resistance of Madsen is governed by two complementary QTLs, Qym1 and Qym2 , located on chromosome arms 2DL and 3BS. Wheat yellow mosaic, caused by Wheat yellow mosaic virus (WYMV), is one of the most serious wheat diseases in East Asia. In this study, recombinant inbred lines (RILs, F9) from a cross between cultivars Madsen(More)
UNLABELLED The mechanism of hypotension induced by anesthetics is not completely understood. Because no electrophysiologic examination of the effects of propofol on the central nervous system has shown its involvement in the control of sympathetic and cardiovascular functions, we investigated the actions of propofol on rat hypothalamic paraventricular(More)
Additional evidence for the rare kaon decay K+-->pi+nu(nu) has been found in a new data set with comparable sensitivity to the previously reported result. One new event was observed in the pion momentum region examined, 211<P<229 MeV/c, bringing the total for the combined data set to two. Including all data taken, the backgrounds were estimated to(More)
Three cases of congenital stationary night blindness are reported. In all patients a negative electroretinogram was recorded by single bright flash stimulation and changed to positive on sequential reduction of the stimulus intensities. Oscillatory potentials were recognized. Biphasic dark adaptation curves and moderate elevation of the relative logarithmic(More)
