cotton are an important source of useful genetic variability (Percival, 1987; Meredith, 1991; McCarty and JenPrimitive accessions of cotton, Gossypium hirsutum L., may prokins, 1992; McCarty et al., 1995). Percival and Kohel vide useful traits for cultivar development. Genetic effects for yield, yield components, and fiber traits were analyzed for five generations (1990) reviewed the collection...

Reactions of Os3(CO)10(NCMe)2 with HGePh3 have yielded the compounds Os3(CO)10(NCMe)(GePh3)(μ-H) (1) and Os3(CO)10(GePh3)2(μ-H)2 (2) by the sequential replacement of the NCMe ligands and the oxidative addition of the GeH bonds of one and two HGePh3 molecules, respectively, to the osmium atoms of the cluster. Compound 2 exists as two isomers in solution at low temperatures which interconvert rap...
