A diallel cross consisting of ten parents was grown on the
Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain
estimates of the gene action contributing to yield and its components
in wheat. Gene action estimates were obtained by two methods of
diallel analysis and from narrow sense heritability...
Experimental crosses between Rana pretiosa pretiosa Baird
and Girard and Rana cascadae Slater, resulted in viable hybrids.
Reciprocal differences at the time of fertilization are indicated. A
high level of success in producing viable hybrids can be obtained if
Rana pretiosa pretiosa is the female of the parent species, The...
