Nine rye genotypes and pollen mixture of three maize cultivars were evaluated for embryo formation in rye x maize crosses. Based on cleared ovule preparations, the development of embryo and endosperm were observed at 48, 72 and 96 h after pollination. Embryos were formed in eight cross combinations (3.3% to 23.3% depending on rye genotype), but in five combinations ovules had both embryos and endosperm nuclei. In a sample of 344 cleared ovules, 28 (8.1%) had both embryo and endosperm, 15 (4.4%) had only embryo, and 13 (3.8%) had only endosperm.

The study presents a comparison of ovulation rate (CL number) and litter size between pure Booroola (BB) and their reciprocal crosses (F1 and F2) with Olkuska sheep. As these breeds express a high reproduction potential and in the same time differ significantly in other performance traits affecting lamb production, it was assumed that their crosses might combine beneficial characteristics of both. When the total numbers of CL were analysed the ovulation rate in BB appeared by 0.6 higher (P≤0.002) than in crossbred ewes (F1 and F2 pooled). However, no such difference was ascertained when analysing the maximum CL numbers. Ovulation rate and litter size did not differ between F1 and F2 crossbred ewes.
