Harvesting time influence on the spring soft wheat seed sowing qualities in the process of growing in the south-east of Western Siberia

Harvesting time influence on the sowing qualities of Baganskaya 95 cultivar spring soft wheat seeds in the process of growing in the south-east of Western Siberia is studied. It was determined that the main factor in formation of the seed sowing qualities is hydrothermal conditions. Low temperatures in July of 2010 (12,3-12,8 оC), August of 2011 (10,9-12,3 оC), as well as shortage of sunshine hours at the time of seed maturity and formation have led to decrease of yield level and conditioned seed yield by 52,4-84,0%.
