Kostanyan, B. A., 1956: Contribution to the problem of the selectivity of impregnation in the sugar and table beets. Izv Akad Nauk Armssr Biol I S Kh Nauki: 33-42Varieties were used for crossing which had contrasting morphological and utilitarian characteristics. Among these were 2 var. of sugar beets: the I-1305 and the sugary V-1612; and two tablebeets, the Bordeaux and Non-pareil. Each var. of sugar beet was crossed with one of the table varieties. The plant pollination and fertilization took place in artificial isolators. It was established that in free intervarietal pollination and with supplemental outside pollination, the sugar beet to a considerable degree selects the pollen of the table beet, although the table beet to a large extent selects its own pollen. First generation plants of both the maternal and intermediary types yield, in the second generation, plants of the intermediary and maternal types, confirming the presence of impregnation (at the first crossing) by outside pollen. A higher percentage of seed setting and greater viability was observed in the plants when cross pollination occurred through its own pollen. Therefore, to obtain plants with a greater viability, it is necessary to use the seeds of pollen from both crossed components.
