Triticale is a promising agricultural crop. The increased content of protein, balanced by the amino acid composition, advantageously distinguishes triticale seed for peeled grains and food concentrates production. Seed cleaning is an important technological operation of food productions, but setting regimes of seed-cleaning equipment for processing triticale seed need specification today. The aim of this work is to study geometric and physical characteristics of four-type triticale seed and elaboration of recommendations as to its cleaning and fractionating. There was studied the fractional composition of four-type triticale seed. The comparative analysis of its length, width and thickness in samples of different sorts and fractions was realized. The dependence of geometric properties of triticale seed on sort is reliable. Fractionating reliably influences the change of the mass index of 1000 seeds, changing from 65,2 g to 25,8 g. The mass index of 1000 seeds essentially differs between studied sorts. Such properties are inherent to seed fractions, obtained by a sieve of 3,2–20 mm and 3,0–20 mm, that are recommended to be called big seeds. Fractions, obtained by a sieve of 2,0–20 and 2,2–20 are analogously similar. Properties of the middle fraction, obtained by sieves of 2,4–20; 2,6–20; 2,8–20 essentially changed, depending on sort. The elaborated recommendations may be used at choosing cleaning regimes for triticale seed on sieve and sieve-air separators.

Тритикале (½ Triticosecale Wittmack) -новая сельскохозяйственная культура, объединяющая в себе ценные свойства пшеницы и ржи. К преимуществам тритикале относятся способность произрастать на бедных, кислых, подтопляемых почвах, более высокое, чем у пшеницы, содержание белка в зерне, устойчивость ко многим грибным заболеваниям. Недостатки тритикале -щуплость зерна, склонность к прорастанию зерна на корню, полеганию, некоторая токсичность зерна вследствие содержания алкилрезорцинолов, а также более длительный по сравнению с родительскими формами вегетационный период. Из всех групп генов наибольшее влияние на продолжительность вегетационного периода злаковых культур оказывают Vrn (response to vernalization, реакция на яровизацию). Яровые растения имеют один или несколько доминантных генов Vrn, у озимых все гены vrn рецессивные. Мягкая пшеница может иметь гены Vrn-A1, Vrn-B1, Vrn-D1, расположенные соответственно в хромосомах 5AL, 5BL, 5DL (A.J. Worland, 1996), ген Vrn-D4 в околоцентромерном районе хромосомы 5D (N. Kippes с соавт., 2015) и ген Vrn-B3 в хромосоме 7BS (L. Yan с соавт., 2006). У ржи ген Vrn-R1 находится в хромосоме 5RL (J. Plaschke с соавт., 1993). У тритикале были обнаружены доминантные аллели Vrn-A1a, Vrn-B1a, Vrn-B1b и Vrn-B1c (M. Nowak с соавт., 2014; О.И. Зайцева с соавт., 2015). Ранее эти аллели были выявлены у мягкой пшеницы (D.K. Santra с соавт., 2009; A.B. Shcherban с соавт., 2012; A.B. Shcherban с соавт., 2015; J. Milec с соавт., 2013; И.Е. Лихенко с соавт., 2014). На время колошения растений влияет не только изменение нуклеотидной последовательности генов Vrn, но и изменение числа копий этих генов (A. Diaz с соавт., 2012). Гены Vrn могут влиять на время колошения и в сочетании друг с другом. Так, сорта с тремя доминантными генами Vrn более раннеспелые, чем с одним или двумя доминантными генами Vrn, но имеют наименьшую продуктивность (A.F. Stelmakh, 1993; M. Iqbal с соавт., 2007). Сообщается, что интрогрессия хромосомы 2D укорачивает период вегетации тритикале (А.А. Шишкина, 2008; Л.В. Корень с соавт., 2010). Растения тритикале имеют более длительный вегетационный период, чем исходные линии пшеницы, что может быть вызвано ингибированием генов Vrn геномом ржи (Л.Н. Каминская с соавт., 2005; I.N. Leonova с соавт., 2005). Генетический контроль типа развития спонтанных яровых мутантов в настоящее время не известен. Большинство яровых мутантов позднеспелые, а при посеве осенью в разной степени перезимовывают, что может указывать на то, что они относятся к двуручкам (П.И. Степочкин, 2008; П.И. Степочкин с соавт., 2008). В Сибири озимые тритикале занимают значительные площади, но по яровым тритикале селекция не ведется. Яровые тритикале могут быть использованы для расширения разнообразия яровых культур. Для селекции представляет интерес создание яровых тритикале с разной продолжительностью вегетационного периода. Ключевые слова: гексаплоидная и октаплоидная тритикале, яровой мутант, пшеница, продолжительность вегетационного периода, гены Vrn.

Robertsonian translocations (RobTs) in the progeny of triticale (×Triticosecale Wittmack) plants with monosomic substitution of Aegilops kotschyi chromosome 2S k (2R) were investigated by fluorescence in-situ hybridization. Chromosome 2S k of Ae. kotschyi is reported to possess many valuable loci, such as Lr54 + Yr37 leaf and stripe (yellow) rust resistance genes. We used a standard procedure to produce RobTs, which consisted of self-pollination of monosomic triticale plants, carrying 2R and 2S k chromosomes in monosomic condition. This approach did not result in RobTs. Simultaneously, we succeeded in producing 11 plants carrying 2R.2S k compensatory RobTs using an alternative approach that utilized ditelosomic lines of triticale carrying 2RS (short arm) and 2RL (long arm) telosomic chromosomes. Identification of molecular markers linked to Lr54 + Yr37 genes in the translocation plants confirmed that these resources can be exploited in current triticale breeding programmes.Agronomy 2019, 9, 646 2 of 12 from wild relatives into the wheat genetic background [10]. Recently, several attempts were made to transfer rust resistance genes from Aegilops, Agropyron and Triticum species into triticale [11][12][13][14][15].Aegilops species are closely related to wheat (and triticale, per se) and carry a number of valuable traits, which have been effectively incorporated into wheat by developing wheat-Aegilops hybrids and deriving addition, substitution and translocation lines [16]. Aegilops kotschyi Boiss. (2n = 4x = 28 chromosomes, U-and S-genomes) is a wild tetraploid goatgrass native to Northern Africa, the Mid-East, and Western Asia. Ae. kotschyi germplasm is exploited in wheat breeding [17] as a source of high grain protein, iron and zinc [18]. Moreover, Antonov and Marais [19] observed leaf rust resistance that was effective against the infection of Puccinia triticina in Ae. kotschyi. Marais et al. [20] identified the Lr54 and Yr37 leaf rust and stripe rust resistance genes, and developed aT2DS.2S k L wheat-Ae. kotschyi translocation line. The first Lr54 + Yr37 marker was developed by Heyns et al. [21]. Moreover, translocation gene sequences were cloned and specific SSR markers were developed [22].Homoeologous recombination based engineering is the most common way for efficiently utilizing the wild relative gene pool for crop improvement [23]. The generation of translocation lines is the most promising pathway for the exploitation of alien germplasm in crop breeding [23]. In distant hybrids, unpaired chromosomes are present as univalents during meiosis. Monosomic chromosomes are prone to centric breaks at anaphase I of meiosis, which misdivide and the broken ends fuse during the interkinesis of meiosis II [24][25][26]. Fusion of the misdivided products may result in the formation of a Robertsonian translocation (RobT) [27].Several steps are required to generate RobTs (Figure 1a), with self-pollination of double-monosomic plants being the most common method used in the induction of RobTs [26]. Wheat breeders can use a l...
