Winter wheat (Triticum aestivum L.) requires vernalization (exposure to temperatures between 1 and 10 °C) to induce heading. Vernalization also induces earlier heading of many spring wheat varieties. Studies of the spring wheat cv. Chinese Spring identified cytogenetic lines of the group 6 chromosomes that were susceptible to chilling injury when seedlings were grown at 6 °C for 8 weeks. Lines that were either ditelocentric for the long arm of chromosome 6D or nullisomic for 6D were susceptible, while those ditelocentric for the short arm of 6D were not. Neither cv. Chinese Spring nor ditelocentrics for either the long or short arms of chromosomes 6A or 6B were susceptible. Susceptible plants selected from F2 seedlings of plants monosomic for 6D were nullisomics. Doublemonotelocentric F1 hybrids from crosses between plants ditelocentric for 6DS or 6DL were resistant, but susceptible F2 seedlings from this cross were either nullisomic for 6D or telocentric for the long arm. The dominant gene(s) that prevents chilling injury at 6 °C appears to be on the short arm of chromosome 6D of cv. Chinese Spring wheat.Key words: chilling injury, wheat, telocentrics, nullisomics, vernalization.

Winter Wheat Cultivars

Aneuploid seedlings of the common wheat (Triticum aestivum L.) cv. Chinese Spring (CS) that are nullisomic or telosomic for the long arm of chromosome 6D are susceptible to chilling injury under prolonged exposure to 6 °C; normal euploids or telosomics for the short arm are not. Studies of seedling grown for various durations at 20 °C prior to growth at 6 °C showed that chilling injury was a juvenile phenomenon and that the extent of injury was inversely proportional to the duration of growth at 20 °C to a maximum of about 14 days. When reciprocal crosses were made between susceptible 6D nullisomics or long-arm ditelocentrics of CS and resistant 6D nullisomics of three spring and one winter wheat cultivars, progenies from aneuploid F1 hybrids all segregated for susceptibility as a recessive trait and at a frequency approximating a dihybrid ratio; no cytoplasmic effects were detected. Aneuploids of the group 6 homoeologues of the spring wheat cvs. Cadet and Rescue were resistant, as were group 6 whole-chromosome substitutions of eight different donor wheats in the recipient parent CS and 56 other euploids tested. Genes for resistance to chilling injury appear to involve the group 6 chromosomes and the short arm of 6D in Chinese Spring. In contrast with chilling injury, all aneuploid lines with only four doses of the "corroded" loci on group 6 chromosomes exhibited chlorotic symptoms.Key words: Triticum aestivum, chilling injury.

AbstractRed wheats (Triticum aestivum L.) are generally more dormant and sprout resistant than white wheats. Whether this is caused by pleiotropic effectsof the red grain colour genes (R) on dormancy and coat colour, or to tight linkage between R and dormancy genes has not been fully resolved. To directly determine the effect of the R1 allele on dormancy, mutations were induced with sodium azide in a pure line selection of the red genotype (R1R1r2r2r3r3) Chinese Spring wheat. Two white mutants (CSW01, CSW02) were recovered from M3 caryopses derived from approximately 20,000 M2 plants. Both mutants were shown to be allelic to a domesticwhite genotype (r1r1r2r2r3r3). Except for seed coat colour, CSW01 and CSW02 are morphologically indistinguishable from the wild type and are presumed to be near isogenic lines of Chinese Spring. Freshly harvested grainsproduced under four different environments were evaluated for post-harvest dormancy. In all environments, intact caryopses of all three isolines exhibited high temperature dormancy typical of cereal species, although the red wild type consistently exhibited greater dormancy than the white mutant isolines. Dormancy was dissipated by afterripening in dry storage at 37°C in a similar manner for the red and white isolines. Excised embryos of the three isolines exhibited similar levels of dormancy and sensitivities to exogenous abscisic acid. These results indicate a functional R1 allele is not absolutely required for dormancy in wheat, but does enhance its expression in caryopses with dormant (sensitive) embryos

Effect On Yield

Where winter wheat (Triticum aestivum L. ’Norstar’) was worked-down on 1 May and the plots reseeded to spring wheat immediately, no detrimental effect on yield of spring wheat was found. However, delaying this action until 15 May reduced the yields of spring-seeded wheat because of the harmful effect of decomposing winter wheat and late seeding. Moisture depletion by winter wheat was eliminated as a causative effect by light irrigations during May. Yields of rapeseed (Brassica campestris L. ’Candle’) were not so severely reduced by worked-down winter wheat. The harmful effect was significant only with 30 May cultivation and seeding date.Key words: Phytotoxicity, Triticum aestivum, Brassica campestris, worked-down

Abstract To study the effect of sodium Selenite application different methods on the yield of spring wheat varieties, depending on the conditions of water supply, a series of vegetation experiments in accordance with the methodology were carried out. The object of the study is spring wheat of the Zlata variety (Triticum aestivum L.). It was found that the effect of selenium on the yield of wheat of the Zlata variety depended on the method of its application and the conditions of water supply. With optimal water supply, the positive effect of selenium on the yield of spring wheat plants was revealed with both methods of applying sodium selenite. It was found that in conditions of drought, the positive effect of selenium was obtained with both methods of using sodium selenite. The greatest efficiency of selenium is obtained in foliar processing of plants. The increase in grain weight in this variant was 1.4 times. The increase in the share of the agronomic significant part of the wheat crop yield to 36% is shown, which indicates the decrease in the negative effect of drought on the formation of spring wheat yield when using foliar processing of plants.
