Distant crossing intermediate Form 2, 3, 5 and 1-all these four intermediate types with common wheat and a sky-blue oat grass chromosome set are selected from the posterities (common wheat × sky-blue oat grass) with common wheat chromosome set AABBDD and sky-blue oat grass chromosome set EE (or FF).Analysis is made on the cells and heredity of the intermediate types. New varieties and lines are established through the crossing between the intermediate type and common wheat. The writer considers that it is of importance in theory and practice to study the cell heredity for the intermedrate types.

Glycine max(L.)Merr. anther cultured in vitro on the modified B5 medium has been produced successfully pollen calli, from which pollen plants were differentiated. Cytological examinations showed that the chromosome set was 2n = 20, indicating that these plants were developed from haploid pollen.Anthers containing early and mid-uninucleate pollen were found to be the optimal stage for culture.The nuclear vegetative in nature derived from unequal or equal division ot the uninucleate pollen in soybean anther cultured in vitro develops into two-celled pollen grain, from which multicellular pollen grain was produced, and calli derived from the multicellular. Under the optimal condition, the green haploid plantlets were differentiated successfully.
