Technological Quality and Yield’s Components of Winter Wheat Lines Under Polish Climatic Conditions
The purpose of the study was to determine the influence of temperature and rainfall on selected quality traits and parameters of the yield structure in the period from kernel filling to maturity. The research material comprised 30 strains and variations of winter wheat collected by the staff of the Plant Breeding and Acclimatization Institute. The following traits were marked: resistance to pre-harvest sprouting, falling number and sedimentation value, protein content, 1000-kernel weight, the number and weight of kernels in an ear as well as the number of days from heading to full maturity.
The least stable trait over the annual periods proved to be the resistance to pre-harvest sprouting and the falling number. It was observed that dry and hot summers tended to shorten the period between kernel filling and maturity and also to increase falling number and sedimentation value. Also, a very high correlation was observed between the number of days without rain and resistance to pre-harvest sprouting. In the years with a high level of rain and a balanced distribution of rainfall, there were significant negative correlations between the number of kernels per ear, on the one hand, and protein content and sedimentation value on the other, and also between the sedimentation value and the kernel weight per ear. In the years with the least number of rainfalls, such correlations were not observed.
