Dependence of Various Oat Ecotypes’ Yield Capacity on Climatic Factors in the Middle Amur Region

Resumo

The experiments took place in the Middle Amur region, which is characterized by uneven soil and climatic conditions. The climate of this area of Russia is characterized by drought during tillering time and an excess of moisture during anthesis, grain ripening, and harvest. The impact of climatic factors on yield formation in oats of various origin were studied. The donors of economically important traits to be used in fodder cereals’ breeding were selected. We found correlations between yield of oats and environmental factors, such as sum of air temperatures at the soil level and precipitation. The oat samples with the best agronomic traits were recognized as promising and were involved in the breeding process as paternal parent forms.
