The feasibility of the hybridization in four species of scallop and the early development of their offsprings;

To utilize rapeseed male-sterile lines,increase the affinity of cruciferae hybridization and breed new vegetable species,the studies conducted the affinity experiments of hybridization, investigated the cytoplasm effection of hybridization,growth vigor,yield and main nourisgment elementsts of tender flower stelk.

This paper studied germination of pollen grains , growth of pollen tubes,fertiliza-tion, development of hybrid embryos and endOsperm in interspecific crosses of genomesamongst G.

napus lines was created by using the method of interspecific cross between early mature B.

The good genes from wild rice can be introduced into the cultivated rice cultivars through the interspecific cross between wild rice and cultivated rice so as to enhance the breeding and production level of the cultivated rice.

The experimental materials were two interspecific hybrids F1(Zhong 86-44×YD1785, Zhong 156×3-66) with traits of completely male sterils between the cultivated rice (AA) and the distant wild species, O.

The results indicated that:it was easier to obtain interspecific hybrid between the same ploidy than between those different in ploidy; cross between D.
