Abstract

Aim. Our goal was to identify sources of increased oil and carotenoid contents in grain and strongly expressed valuable economic traits in a new corn collection of the National Center for Plant Genetic Resources of Ukraine.

Result and Discussion. Forty-three corn lines with various grain consistency were analyzed. There were  significant inter-line differences in the contents of β-carotene and oil. The β-carotene content in grain varied from 0.89 to 18.88 mg/kg; the oil content - from 3.10 to 7.24 mg/kg. In the studied material, the following lines with increased content of β-carotene (5.44–6.77 mg/kg) were distinguished: flint lines UKhK 549, UKhK 656, UKhK 719, UKhK 731, UKhK 732, UKhS 107, UKhS 227, Kharkivska 548, and others (UKR), AG 15-3030 (MDA); flint-dent lines UKhK 414, UKhK 746, UKhK 749, UKhS 236, UKhF 124, KhaA 408, Kharkivska 125 MV (UKR), MAS 24C (FRA). All of these lines exhibit elevated levels of oil (5.36-10.50 mg/kg) in grain, are highly productive (47-96 g of grain per plant), have a lot of kernels per cob (412-442) and high thousand-kernel weight (235-262 g). These lines are sources of high carotene and oil contents for breeding to create hybrids.

Conclusions. The results on identification of new corn collection accessions with improved grain quality from the National Center for Plant Genetic Resources of Ukraine are presented. Modern corn lines of different ripeness groups and origins have been selected: UKhK 656, UKhK 549, UKhK 657, UKhK 746, UKhF 124 (UKR), AG 15-3030 (MDA), MAS 24C (FRA); these lines combine the main agronomic traits, such as plant productivity, kernel number per cob, and thousand-kernel weight, with high β-carotene and oil contents in grain. The study has confirmed that one genotype can combine high carotene and oil contents in grain with strong expression of valuable economic traits. The results show that in the analyzed corn lines with with various grain consistency the mean contents of β-carotene and oil in grain varied: the β-carotene content ranged from 0,89 to 18,88 mg/kg and the oil content - from 3,10 to 7,24 mg/kg.
