“…There are a number of publications that reported about estimation of combining ability and gene action for different traits in spring (Kumari et al, 2020;Darabad et al, 2021a) and winter (Ciulca et al, 2015;Bernhard et al, 2017) barley. There are articles dedicated to study of grain yield and its components in barley under relatively normal (Panwar & Sharma, 2019;Katiyar et al, 2021;Zymogliad et al, 2021) and stress condition, such as drought (Sultan et al, 2016), salinity (Mansour et al, 2016), nitrogen (Abdel-Moneam & Leilah, 2018), as well as assesment of genetic control of the "seedlings-earing" interphase period (Vashchenko & Shevchenko, 2021). There is also a study of combing ability in six-rowed barley (Hordeum vulgare L.) (Lal et al, 2018).…”

The purpose of the present study is to identify breeding and genetic peculiarities for productive tillering in spring barley genotypes of different origin, purposes of usage and botanical affiliation, as well as to identify effective genetic sources to further improving of the trait. There were created two complete (6 × 6) diallel crossing schemes. Into the Scheme I elite Ukrainian (MIP Tytul and Avhur) and Western European (Datcha, Quench, Gladys, and Beatrix) malting spring barley varieties were involved. Scheme II included awnless covered barley varieties Kozyr and Vitrazh bred at the Plant Production Institute named after V. Y. Yuriev of NAAS of Ukraine, naked barley varieties Condor and CDC Rattan from Canada, as well as awned feed barley variety MIP Myroslav created at MIW and malting barley variety Sebastian from Denmark. For more reliable and informative characterization of barley varieties and their progeny for productive tillering in terms of inheritance, parameters of genetic variation and general combining ability (GCA) statistical analyses of experimental data from different (2019 and 2020) growing seasons were conducted. Accordingly to the indicator of phenotypic dominance all possible modes of inheritance were detected, except for negative dominance in the Scheme I in 2020. The degree of phenotypic dominance significantly varied depending on both varieties involved in crossing schemes and conditions of the years of trials. There was overdominance in loci in both schemes in both years. The other parameters of genetic variation showed significant differences in gene action for productive tillering between crossing Schemes. In Scheme I in both years the dominance was mainly unidirectional and due to dominant effects. In the Scheme II in both years there was multidirectional dominance. In Scheme I compliance with the additive-dominant system was revealed in 2019, but in 2020 there was a strong epistasis. In Scheme II in both years non-allelic interaction was identified. In general, the mode of gene action showed a very complex gene action for productive tillering in barley and a significant role of non-genetic factors in phenotypic manifestation of the trait. Despite this, the level of heritability in the narrow sense in both Schemes pointed to the possibility of the successful selection of individuals with genetically determined increased productive tillering in the splitting generations. In Scheme I the final selection for productive tillering will be more effective in later generations, when dominant alleles become homozygous. In Scheme II it is theoretically possible to select plants with high productive tillering on both recessive and dominant basis. In both schemes the non-allelic interaction should be taken into consideration. Spring barley varieties Beatrix, Datcha, MIP Myroslav and Kozyr can be used as effective genetic sources for involvement in crossings aimed at improving the productive tillering. The results of present study contribute to further development of studies devoted to evaluation of gene action for yield-related traits in spring barley, as well as identification of new genetic sources for plant improvement.

“…Rajasthan, Uttar Pradesh, Madhya Pradesh and Haryana are major barley producing states in India. Due to the inherent tolerant capability of barley for drought, salinity, heat, early maturity and low water conditions the crop is one of the favoured traditional crops of MP and UP Bundelkhand region (Elakhdar et al, 2023, Panwar andSharma, 2019).…”

The present study was carried out during November–April, 2019–2020 and 2020–21 with eight diverse barley genotypes and their developed 28F1s (half diallel, excluding reciprocals) to ascertain gene effects, hetrosis and correlations for grain yield, yield attributes and physiological traits under water limited conditions of Bundelkhand region. Days to heading and days to maturity exhibited general mean values of 86 days and 127 days, respectively. The parental genotypes, DWRB180, RD2794 and RD2899 showed early spike emergence and maturity. The cross combinations, namely DWRB160 /DWRB180, DWRB180/RD2907 and BH946/RD2552 were promising for flag leaf length and width. The GCA effects were significant and prevalent for all the characters, except days to heading, plant height and tillers count. The parents, DWRB160 (5.29**) and BH902 (1.59**) depicted high GCA effects for 1000 grain weight. The parents, DWRB180, RD2552, and BH946 exhibited significant positive GCA effects for leaf area index and chlorophyll fluorescence, whereas the genotypes, RD2907, BH946 and RD2899 showed higher GCA effects for chlorophyll content. Grain yield exhibited significant positive correlations with flag leaf width (0.60**), tillers per meter (0.35*), grains per spike (0.39*), harvest index (0.53**), chlorophyll content (0.69**), leaf area index (0.49**) and chlorophyll fluorescence (0.68**). The parents, BH946, DWRB180 and RD2907 and the hybrids, RD2552/DWRB180, BH902/RD2794, DWRB160/DWRB180 and BH946/RD2907 were found promising for yield and yield attributes in the dry agro-ecology of Bundelkhand region. The crosses, DWRB160/BH902 and DWRB160/BH946 can be explored for developing superior segregants for malt barley breeding.

Purpose. To reveal the peculiarities of inheritance of kernel number per spike in crosses of spring barley cultivars of different origin, purpose of use and botanical varieties, as well as to distinguish effective genetic sources for improving the trait. Methods. The study was carried out at the M. Remeslo Myronivka Institute of Wheat of National Academy of Agrarian Sciences of Ukraine in 2019 and 2020. In F1 of spring barley in two diallel crossing schemes the degree of phenotypic dominance, parameters of genetic variation, and combining ability for kernel number per spike were determined. Results. According to the indicator of the degree of phenotypic dominance, all possible types of inheritance of kernel number per spike were identified. In a number of crossing compositions, a change in the type of inheritance depending on the conditions of the year was revealed. Most combinations with overdominance in both years were noted in crossings of the covered awned cultivar ‘Avgur’, as well as the covered awnless cultivar ‘Kozyr’. According to the parameters of genetic variation in crosses of malting varieties (covered awned), correspondence of the additive-dominant model, overdominance and dominance in loci, as well as unidirectional dominance to increasing of the trait caused by dominant effects were revealed. When crossing cultivars of different varieties, a change in gene action in different years was found. In particular, additive-dominant system changed to complementary epistasis, incomplete dominance to overdominance, unidirectional dominance to increasing of the trait to multidirectional dominance. The genetic sources of increased general combining ability were identified, as follows: covered awned malting cultivars ‘Quench’ and ‘Avgur’, the naked awned cultivar ‘CDC Rattan’, as well as the covered awnless cultivar ‘Kozyr’. Based on the constants of specific combining ability, the most promising crossing combinations for further breeding efforts were determined. Conclusions. The identified peculiarities of the inheritance of kernel number per spike make it possible to optimally combine parental components of crossings and carry out directional selection to increase the trait when developing spring barley cultivars for different use and different botanical varieties.
