Abstract
*Corresponding author e-mail: marian.wiwart@uwm.edu.pl **This work was financially supported by Minister of Education and Science in the range of the program entitled “Regional Initiative of Excellence” for the years 2019-2022, Project No. 010/ RID/2018/19, amount of funding 12.000.000 PLN. A b s t r a c t. The nutrient content and the morphological and anatomical features of kernels were compared for 11 breeding lines of tritordeum and three Triticum durum cultivars. The kernel shape descriptors were examined using digital image analysis, and the contents of four basic nutrients were determined. Tritordeum grain had a significantly higher content of protein, fat, ash and fibre than durum wheat grain. In turn, the values of one kernel weight, kernel thickness and hardness were significantly lower in tritordeum. Tritordeum kernels are elongated, relatively small, with a deep crease and a small cross-sectional area. All lines differed considerably with regard to the examined phenotypic attributes. Tritordeum lines and the reference cultivars were most effectively distinguished based on fibre content, spike length, spikelet number per spike, and kernel number and weight per spike. One kernel weight, whole kernel area, crease depth, and the distance from the bottom of the crease to the kernel edge were the least distinguishing traits. The results indicate that tritordeum grain can accumulate more than 19% protein and 43% more fibre than durum wheat in Central Europe. The examined tritordeum lines are highly promising despite the fact that their yield potential is twice lower compared to modern T. durum cultivars.

期刊介绍:
The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed.
Particularly the journal is focused on the following areas:
implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment,
soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture,
postharvest management and processing of agricultural and horticultural products in relation to food quality and safety,
mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing,
advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments.
Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used.
All manuscripts are initially checked on topic suitability and linguistic quality.
