Collection of the Ustymivka Experimental Station as a source of original material for maize breeding with improved biochemical indices of corn
Journal Title: Plant varieties studying and protection - Year 2018, Vol 14, Issue 1
Abstract
Purpose of this work is to identify promising samples of corn from the collection of Ustymivka Experimental Station of Plant Production with important biochemical indicators of quality – high protein and starch content. Methods. Field, laboratory, summarizing. Results. The grading of the collection samples of corn according to biochemical indicators was carried out. Only one line with a very high protein content of 15.8% was allocated – ‘UHK 464’ (Ukraine). 57 lines and 35 varieties of different eco-geographical origin had the high level of protein content. This makes it possible to select valuable forms. Among self-polluting lines, the sources of very high protein content (14.0–15.0%) include: ‘UH 220’, (Ukraine) and ‘A 27-51’, ‘R 168’ (USA). 10 varieties of maize had the corn protein content within 12.0–12.9%, the best of them are conventional variety ‘UB0104037’ (Russia) and UB0100419 ‘Cuzco’ (Mexico). Among the maize lines created with the wx, se, o2, ae, su1, su2, sh2 genes, some corn samples were identified as a combination of high productivity with increased protein content. Very high content of starch in corn (70.0–75.5%) was found in 147 samples, including 39 lines and 108 varieties. Only 3 lines had a starch content of more than 76.0% – ‘HLG 4’ and ‘A 169’ (Ukraine), ‘7023’ (Germany). This indicator varies within the limits of 73–75% in 23 maize lines. The best of them are ‘LK 14795’, ‘UHK 383’, ‘UHR 74-2’ (Ukraine), ‘MA 23 S’ (France), ‘B 312’ (Russia), ‘LH 59’ (USA), ‘ВС 70511’ (Croatia), ‘N 4-1-6’ (Serbia and Montenegro), ‘Martonvasar 1’, ‘Martonvasar 2’ (Hungary). It is recommended to use self-pollinated lines ‘G 6’, ‘CO 72-75-13 PR’, ‘D-BE-14’, ‘W 117’, ‘407’, ‘P 502 ZM’, ‘UHK 565’, ‘Oh 45’ in the maize selection process for hybrids and lines with the high content of protein and starch. This provides a valuable source material, which will serve as the basis for the priority directions of maize breeding. Conclusions. Based on the results of the study, a valuable original material for maize lines and hybrids breeding with improved biochemical composition of corn was formed. The studied corn samples are in the collections of the Ustymivka Experimental Station and the National Centre for Plant Genetic Resources of Ukraine and can be used by breeders and other consumers in theoretical and practical developments.
