    Notes: Abstract The γ radiation from the ß− decay of the high-spin isomer in98Y has been studied at the separator JOSEF. A main goal was to get insight into the spins of levels in98Zr which have been interpreted as members of an intruder band based on the 02 + state at 854 keV. The measuredγ-γ angular-correlations lead to the assignment of spins of 4 and 3 ℏ to the 2491 and 1844 keV levels, respectively, and contradict their interpretation as the 6+ and 4+ states of the proposed band. For the 2.0s isomer of98Y, the ß{−}-decay properties suggest I=5 with a major configuration [πg9/2,νs1/2(g2 7/2)0].

    Notes: Abstract The Hessian fly [Mayetiola destructor (Say)] is a major pest of wheat (Triticum aestivum L.) and genetic resistance has been used effectively over the past 30 years to protect wheat against serious damage by the fly. To-date, 25 Hessian fly resistance genes, designated H1 to H25, have been identified in wheat. With near-isogenic wheat lines differing for the presence of an individual Hessian fly resistance gene, in conjunction with random amplified polymorphic DNA (RAPD) analysis and denaturing gradient-gel electrophoresis (DGGE), we have identified a DNA marker associated with the H9 resistance gene. The H9 gene confers resistance against biotype L of the Hessian fly, the most virulent biotype. The RAPD marker cosegregates with resistance in a segregating F2 population, remains associated with H9 resistance in a number of different T. aestivum and T. durum L. genetic backgrounds, and is readily detected by either DGGE or DNA gel-blot hybridization.
