Effect Of Plantitng Pattern Of Winter Wheat On Agrodiversity
T. Z. Moskalets
We studied the introductions of cultivars and lines of wheat soft winter wheat that are adaptive to specific physical and climatic conditions ecotopes regards forest-steppe and Polissia ecotypes by ecological and biological characteristics. We also determined their influence on formation of the diversity and productivity of agricultural ecosystems. It was established that mosaic planting pattern of winter wheat allows to get a high yield (up to 9 t/ha) and of strong and superstrong wheat (Ariivka, L 4696/96, KC-5, KC-7, KC-14, KC-22, Yuvivata 60, etc.) in comparison to monocultivar technology. Some genotypes, namely Yuvivata 60, Ariiivka KC-22, KC-7 have moderate and high resistance towards complex diseases. The mosaic planting pattern of cultivars is the important factor of increasing the diversity and strengthening the links in agricultural ecosystems. Based on the long-term ecological research of genetic forms of winter soft wheat in different ecotopes and comparing them by major agronomic features with cultivar-standards we selected some promising cultivars and lines. We suggested the semi dwarf, medium-grown productive, and high adaptive genotypes of wheat soft winter, like Prydesnianska, Ariiivka, Nosshpa 100, ???-5, ???-7, ???-14, ???-21, ???-22, Yuvivata 60, Zoriana Nosivska, ???-16, ???-17, ??9646/96.
