“…Buckwheat is short duration and fast growing crop and completes the life cycle from seeds to seeds in 70-90 days (Campbell 1995). Buckwheat possesses a shallow taproot system extending up to 1-2.0 m. depth and constitutes 3-4% of total plant biomass (Woo et al 2016). The shallow root system makes the buckwheat plant susceptible to extreme moisture stress conditions, which usually occur in delayed planting conditions (Campbell 1997).…”

“…Common buckwheat (F.esculentum) is a widely cultivated species from Asia to Europe, North America and South Africa, whereas tartary buckwheat (F.tataricum) and F.cymosum are mainly confined to highlands of southwest China and Himalayas (Ohnishi 1998;Zhou et al 2016). By virtue of its rich nutrient composition, there has been an increased interest in consumption of buckwheat as functional food such as naengmyeon (Korean cold noodles), Chinese noodles, Japanese soba and as an ingredient of cake, bread, pasta and pancake mixes in Asia, Europe, North America and Canada (Campbell 1997;Lee et al 2016). The nutritional superiority over major cereals in terms of balanced amino acid profile of seed protein (Table 1) and bioactive flavonoids of diverse pharmaceutical uses makes it a highly valuable crop.…”

Main conclusion Emerging insights in buckwheat molecular genetics allow the integration of genomics driven breeding to revive this ancient crop of immense nutraceutical potential from Asia.Out of several thousand known edible plant species, only four crops-rice, wheat, maize and potato provide the largest proportion of daily nutrition to billions of people. While these crops are the primary supplier of carbohydrates, they lack essential amino acids and minerals for a balanced nutrition. The overdependence on only few crops makes the future cropping systems vulnerable to the predicted climate change. Diversifying food resources through incorporation of orphan or minor crops in modern cropping systems is one potential strategy to improve the nutritional security and mitigate the hostile weather patterns. One such crop is buckwheat, which can contribute to the agricultural sustainability as it grows in a wide range of environments, requires relatively low inputs and possess balanced amino acid and micronutrient profiles. Additionally, gluten-free nature of protein and nutraceutical properties of secondary metabolites make the crop a healthy alternative of wheat-based diet in developed countries. Despite enormous potential, efforts for the genetic improvement of buckwheat are considerably lagged behind the conventional cereal crops. With the draft genome sequences in hand, there is a great scope to speed up the progress of genetic improvement of buckwheat. This article outlines the state of the art in buckwheat research and provides concrete perspectives how modern breeding approaches can be implemented to accelerate the genetic gain. Our suggestions are transferable to many minor and underutilized crops to address the issue of limited genetic gain and low productivity.

“…Buckwheat grain is rich in high-quality proteins and contains well-balanced amounts of essential amino acids (i.e., lysine, methionine, cysteine, tryptophan). In addition, common buckwheat is important as a nectariferous plant, and both Tartary and common buckwheat are pharmaceutical plants [ 97 , 98 , 99 , 100 ]. In recent buckwheat breeding programs, particular properties have been investigated, such as high grain yield, frost resistance, increased protein content, reduced allergenic protein content [ 97 ].…”

People with multiple allergies can also develop an allergy when eating buckwheat [ 85 ], which can be caused by low-molecular-weight proteins in the grain embryo (i.e., 18–29 kD) [ 84 , 100 , 101 , 102 , 103 , 104 , 105 ].…”

Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.) and common buckwheat (Fagopyrum esculentum Moench) are important sources of proteins with balanced amino-acid compositions, and thus of high nutritional value. The polyphenols naturally present in Tartary buckwheat and common buckwheat lower the true digestibility of the proteins. Digestion-resistant peptides are a vehicle for fecal excretion of steroids, and in this way, for bile acid elimination and reduction of cholesterol concentrations in serum. Buckwheat proteins are more effective compared to soy proteins for the prevention of gallstone formation. Tartary and common buckwheat grain that contains appropriate amounts of selenium-containing amino acids can be produced as functional food products. The protein-rich by-products of buckwheat are a good source of bioactive substances that can suppress colon carcinogenesis by reducing cell proliferation. The grain embryo is a rich source of proteins, so breeding buckwheat with larger embryos is a possible strategy to increase protein levels in Tartary and common buckwheat grain. However, chemical analysis of the grain is the most relevant criterion for assessing grain protein levels and quality.

“…The yield of common buckwheat is generally affected by its seed-set, with a low seed-set resulting in a lower seed yield (Woo et al, 2016). Furthermore, lodging, i.e., the tendency of the stem to bend until the plant is lying horizontal, is one of the serious problems affecting buckwheat and resulting in a drastic decline of seed yield (Tetsuka and Morishita, 1999) Darumadattan has been shown to have improved agronomic characteristics and strong lodging resistance (Morishita et al, 2010;Kasajima et al, 2012;2014).…”

Seed-setting habit of a semidwarf common buckwheat line

The seed-setting habit of a semidwarf common buckwheat (Fagopyrum esculentum Moench) line was evaluated in a field experiment under standard and high nitrogen levels. The 'semidwarf line' and 'Kitawasesoba' were used in the present study. The main stem length of the 'semidwarf line' was approximately two thirds of that of the 'Kitawasesoba'. Minimal differences were observed in the numbers of nodes on the main stem and primary branches of the 'semidwarf line' and 'Kitawasesoba' among genotypes and nitrogen levels. No drastic decline of seed yield by the shortening of the main stem length along with the introduction of dwarfness was observed in the 'semidwarf line' compared with 'Kitawasesoba'.The number of flower clusters per plant of the 'semidwarf line' in the high nitrogen plot tended to be greater than that of the 'semidwarf line' in the standard nitrogen plot and 'Kitawasesoba' in both nitrogen plots. This increase in flower clusters occurred on branches. The number of seeds of the 'semidwarf line' in the standard nitrogen plot was considerably lower than that of the 'Kitawasesoba' in both nitrogen plots. Similar tendencies were observed in the weights of seeds. The decline of seed number and weight of the 'semidwarf line' in the standard nitrogen plot was mainly observed in branches. From these results, it was found that the seed-set in the 'semidwarf line' can be improved by nitrogen fertilizer application.
