Notes: Abstract Using the genomic in situ hybridization (GISH) technique, one translocation line, seven translocation-addition lines, five translocation plus translocation addition lines and two ditelosomic addition lines were identified in backcross progenies of Triticum aestivum L. -Psathyrostachys juncea (Fisch.) Nevski intergeneric hybrids. No complete P. juncea chromosomes were detected in the 25 lines studied. The results suggest that intact P. juncea chromosomes may be difficult to isolate in a wheat background.

Notes: Conditions are reported for the reverse-phase HPLC analysis of gossypol and of some of its derivatives, including anhydrogossypol, gossypolone, gossypol hexaacetate, and Schiff's base derivatives. It is shown that field desorption (FD) and chemical ionization (CI) mass spectrometry have advantages over electron impact (EI) mass spectrometry for the characterization of these compounds and that combined high-performance liquid chromatography/mass spectrometry (LC/MS), especially when used in the CI mode, is particularly effective.
