The main problems encountered in breeding winter rye in the northwestern region are: winterhardiness, lodging resistance, disease resistance and grain quality. Winterhardiness in the northwest of the USSR depends on the resistance of rye to snow mould. Varieties from the USSR (Vyatka, Falenskaja, Udinskaja, Narymskaja 23 and some others) and Austria (Lungauer Tauern, Schlager) as well as many varieties from Finland present valuable material for breeding for winterhardiness. The breeding of short-strawed varieties was promoted considerably by the use of donors with the dominant type of inheritance of the short straw characteristic (EM-1, k-10028) and many forms and varieties created on their basis. Nine commercial varieties with a high yield potential and winterhardiness were bred. Short-strawed donors resistant to powdery mildew and brown rust (Imering 4, Fletera 2, Immunnaja 5), unique in their kind and very valuable, were bred by introgression of the genes for resistance, which had been discovered in the populations of wild species and older varieties. A strategy of breeding rye for disease resistance is suggested. In breeding to improve grain quality, a gene bank of varieties, in which the stability of high grain quality is retained, is valuable. Some varieties have a protein content in the grain of 10 %, with a lysine content in the protein of 4 % or more (Marienhofer, Wieselburger, Kisvardai). Four short-strawed analogues of commercial varieties (Ural’skaja HI, Tchishminskaja HI, Kustro HI, Stalrug HI) are close to the variety Otello as to their baking qualities. The material presented on the inheritance of characteristics contributes to the selection of donors when new varieties are bred.

High Yield Potential

In Chile, durum wheat is cultivated in high-yielding Mediterranean environments, therefore breeding programs have selected cultivars with high yield potential in addition to grain quality. The genetic progress in grain yield (GY) between 1964 and 2010 was 72.8 kg ha−1 per year. GY showed a positive and significant correlation with days to heading, kernels per unit ground area and thousand kernel weight. The gluten and protein content tended to decrease with the year of cultivar release. The correlation between the δ13C of kernels and GY was negative and significant (−0.62, p < 0.05, for all cultivars; and −0.97, p < 0.001, excluding the two oldest cultivars). The yield progress (genetic plus agronomic improvements) of a set of 40–46 advanced lines evaluated between 2006 and 2015 was 569 kg ha−1 per year. Unlike other Mediterranean agro-environments, a longer growing cycle together with taller plants seems to be related to the increase in the GY of Chilean durum wheat during recent decades.

The article presents the results of screening of 20 varieties of fiber flax (Linum usitatissimum L.) according to the yield of flax fiber and adaptability parameters in the conditions of the Northwestern region. The variety Dobrynya (Russia) zoned in the region was taken as standard. On average, over the years of research (2015-2017), the yield of flax fiber in varie-ty numbers varied in the range of 1.22-2.67 t/ha. According to the calculations of the environmental conditions index, the most favorable conditions for growth and development of fiber flax varieties were in 2016-2017 (Ij = +0.07-0.73), the worst in 2015 (Ij = -0.79). The highest yield of fiber (t/ha) was observed in varieties Y 51269 (2.67) (China), A-236 (2.66), Dobrynya (2.49), M-249 (2.48) and L 280-02 (2.38) (Russia), Glazur (2.48) (Ukraine), which exceeded the average among the varieties by 9.7-2.3 %. Among them, the varieties Y 51269 (China) and A-236 (Russia) exceeded the standard by 0.17-0.18 t/ha, in two years of three the growth was reliable. The studied varieties did not fully realize their relatively high yield potential and were characterized by a strong degree of variability. The best indicators of stress resistance (0.79-1.16) were observed in Vesnichka, L-2 (Russia), B-226 (Lithuania), Tyy (China) the varieties and lines Dobrynya, M-249, A-236, L-6, L-4, L-5, L 280-02 (Russia), Glazur, Vruchiy (2.34-2.32) (Ukraine) and Tyy (2.33) (China) were genetically flexible genotypes (2.56-2.23). Samples B-226 (Lithuania), Glazur (Ukraina), L-2-1, Vesnichka, and L 280-02 (Russia) had high homeostatic values and low coefficient of variation. Highly responsive to environmental conditions were samples L-5, L-3, L-4, A-236, M-249, Dobrynya, (Russia), Sxy20, Sxy, Y 51269 (China), Vruchiy (Ukraine); plastic ˗- varieties Glazur (Ukraine), L 280-02, L-5-1, 85-58-26-20 (Russia); weakly responsive − Lu-1, Tyy (China), L-2-1, L-205, Vesnichka (Russia), B-226 (Lithuania). According to the yield of flax fiber and the complex of adaptability parameters, the cultivars B-226 (Lithuania), Y 51269 , Tyy, Lu 1 (China), L 280-02, L-6, A-236, Dobrynya (Russia), Vruchiy and Glazur (Ukraine) were distinguished. They had high stress resistance, genetic flexibility, plasticity and stability. They can be used as sources of adaptability when creating new varieties of fiber flax.

Rainfed Wheat

The improvement in grain yield of wheat throughout Australia through both breeding and management has been impressive. Averaged across all farms, there has been an approximate doubling of yield per unit area since ~1940. This has occurred across a broad range of environments with different rainfall patterns. Interestingly, the gain in the driest years (9 kg ha–1 year–1 or 0.81% year–1) has been proportionally greater than in the most favourable years (13.2 kg ha–1 year–1 or 0.61% per year) when expressed as yield relative to 2012. These data from all farms suggest that further yield progress is likely, and evidence is presented that improved management practices alone could double this rate of progress. The yield increases achieved have been without any known compromise in grain quality or disease resistance. As expected, improvements have come from both changed management and from better genetics, as well as from the synergy between them. Yield improvements due to changed management have been dramatic and are easiest to quantify, whereas those from breeding have been important but more subtle. The management practices responsible have largely been driven by advances in mechanisation that enable direct seeding, more timely and flexible sowing and nutrient management, and improved weed and pest control, many of which have been facilitated by improved crop sequences with grain legumes and oilseeds that improve water- and nutrient-use efficiency. Most of the yield improvements from breeding in Australia have come from conventional breeding approaches where selection is almost solely for grain yield (together with grain quality and disease resistance). Improvements have primarily been through increased harvest index (HI), although aboveground biomass has also been important. We discuss future opportunities to further increase Australian rainfed wheat yields. An important one is earlier planting, which increases resource capture. This will require knowledge of the genes regulating phenological development so that flowering still occurs at the optimum time; appropriate modifications to sowing arrangements and nutrient management will also be required. To improve yield potential, we propose a focus on physiological traits that increase biomass and HI and suggest that there may be more scope to improve biomass than HI. In addition, there are likely to be important opportunities to combine novel management practices with new breeding traits to capture the synergy possible from variety × management interactions. Finally, we comment on research aimed at adapting agriculture to climate change.

The Stability

The phenotypic analysis of new candidate varieties at multiple locations could provide information on the stability of their genotypes. We evaluated the stability of 11 maize hybrid candidates in five districts in East Java Province, Indonesia. Maize hybrids with high yield potential and early maturity traits derived from a diallel cross were planted in a randomized complete block design with two checks (Srikandi Kuning and BISI-2) as a single factor with four replicates. The observed traits were grain yield per hectare and harvest age. The effects of environment, genotype, and genotype × environment interaction on yield were highly significant (P < 0.01). KTM-1, KTM-2, KTM-4, KTM-5, and KTM-6 showed higher average grain yield per hectare than the checks (Srikandi Kuning = 8.49 ton ha−1 and BISI-2 = 7.32 ton ha−1) at five different locations. The average harvest age of 11 candidates was less than 100 days. KTM-4 and KTM-5 had production yields that were higher than the average yield of all genotypes in all environments (Yi > 7.78 tons ha−1) and were considered stable on the basis of three stability parameters, i.e., Finlay–Wilkinson, Eberhart–Russell, and additive main effect multiplicative interaction (AMMI). KTM-2 had the highest yield among all tested genotypes (9.33 ton ha−1) and was considered as stable on the basis of AMMI but not on the basis of Finlay–Wilkinson and Eberhart–Russell. KTM-1 performed well only in Pamekasan, whereas KTM-6 performed well only in Sampang. Thus, these two genotypes could be targeted for these specific locations.

Sorghum (Sorghum bicolor (L) Moench) is the most widely produced and consumed cereal crop in Sudan. However, productivity is low since the crop is produced in favorable and unfavorable environments where the crop suffers from drought stresses at different growth stages. In the present study, six sorghum inbred lines developed by local breeding program and two commercial checks were evaluated for grain yield potential, yield stability, some important agronomic characters and grain quality properties. Series variety trials were conducted at Elobeid and Suki, Damazin areas of Sudan, during three consecutive rainy seasons. The selected locations represent low, medium and high rainfall areas of Sudan. The trial was laid out in a randomized complete block design. The results revealed that mean squares of genotypes, seasons, locations, location x season, location x genotypes, season x genotypes and season x location x genotype interactions were highly significant (P=0.01) for grain yield. The sorghum genotypes Edo 34-23-4, Edo 26-18 and Edo 16-dwarf produced substantially higher grain yields than commercial checks and the trial mean. Their percentage yield increase ranged from 5% to 75% over commercial checks. The stability analysis revealed that the above mentioned Edo-genotypes had high yield potentials and were stable across a wide range of agricultural conditions. Moreover, the same Edo-lines showed early maturing compared to selected commercial checks and also the Edo-lines possessed good food grains and were market preferred and acceptable for making quality kisra (fermented sorghum pancake-like flatbread). The Edo developed lines also possess the acceptable grain quality in addition to moderate physical grain characteristics such as protein content, fat acidity and moisture content.

Sixteen rice genotypes were planted under normal and high temperature during 2018 and 2019 seasons to understand the mechanisms that make plants tolerant or susceptible to heat stress and methods which may lead to generate new varieties with sustainable yield production. The combined analysis showed significant differences at the level of probability 0.05 and 0.01 among years for all characters except, chlorophyll content and leaf rolling which would indicate wide differences among the weather of both years. Environment’s variance was significant at the level of probability 0.01 over all characteristics. The significant differences at the level of probability 0.01 were recorded among genotypes and G x E interaction variances for all characteristics. The highest values of panicles number plant-1 were obtained from ‘Giza 178’ and ‘Hybrid 2’, however, the highest values of 100-grain weight were recorded with ‘Giza 179’ and ‘Egyptian Yasmine’. The minimum values of sterility% were recorded with ‘Sakha 107’ and ‘IET1444’. Concerning the cultivars performance across two environments, the cultivars ‘Giza 178’, ‘Giza 179’, ‘Sakha 107’ and ‘IET 1444’ gave the best desirable values over natural and heat stress so, those cultivars are considered to play a vital role in breeding program to enhance heat stresses tolerance accompanied with high yield potential.
