“…Therefore, efforts to convert quinoa into a major crop must aim to increase yield, achieve yield stability, and reduce the saponin content of the seed ( Rao and Shahid, 2012 ; Choukr-Allah et al , 2016 ; Ruiz et al , 2017 ; Gamboa et al , 2018 ; Präger et al , 2018 ). Because quinoa displays a natural resilience to adverse environmental factors, breeding goals for quinoa require crop improvements that optimize productivity with minimum inputs ( Zurita-Silva et al , 2014 ; Yabe and Iwata, 2020 ).…”

Abstract Crops tolerant to drought and salt stress may be developed by two approaches. First, major crops may be improved by introducing genes from tolerant plants. For example, many major crops have wild relatives that are more tolerant to drought and high salinity than the cultivated crops, and, once deciphered, the underlying resilience mechanisms could be genetically manipulated to produce crops with improved tolerance. Secondly, some minor (orphan) crops cultivated in marginal areas are already drought and salt tolerant. Improving the agronomic performance of these crops may be an effective way to increase crop and food diversity, and an alternative to engineering tolerance in major crops. Quinoa (Chenopodium quinoa Willd.), a nutritious minor crop that tolerates drought and salinity better than most other crops, is an ideal candidate for both of these approaches. Although quinoa has yet to reach its potential as a fully domesticated crop, breeding efforts to improve the plant have been limited. Molecular and genetic techniques combined with traditional breeding are likely to change this picture. Here we analyse protein-coding sequences in the quinoa genome that are orthologous to domestication genes in established crops. Mutating only a limited number of such genes by targeted mutagenesis appears to be a promising route for accelerating the improvement of quinoa and generating a nutritious high-yielding crop that can meet the future demand for food production in a changing climate.

“…Among millets, mainly foxtail millet, pearl millet, finger millet, job’s tear ( Coix lacrymajobi ) and tef ( Eragrotis tef ) have been investigated for development of genetic and genomic resources (Dwivedi et al 2012 ; Sood et al 2016 ; Babu et al 2018 ). Similarly, pseudo-cereals like Buckwheat Amaranth and Chenopods, and under-utilized pulses have also witnessed good progress in identification of genomic resources for important traits in recent years (Joshi et al 2018 , 2019 ; Pattanayak et al 2019 ; Yabe and Iwata 2020 ).…”

Selective production of input intensive crops in the present scenario have resulted in productivity stagnation or even decline due to excessive usage of chemicals, affecting the farmers economically. Sustainable agriculture is the way to increase agricultural productivity and economic prosperity by protecting all natural resources. It maintains a balance of soil fertility with crop productivity and nutritional quality. The mixed cropping systems followed earlier in different regions according to their tradition, climatic zone, soil and water conditions were climate-smart approaches to sustainable food production based on practical experiences over the years of old generations. The life style changes, imbalance in farming system in last 70 years and demand for more food as well as declining land resources resulted in intensive agriculture. Besides, least returns and less demand of ethnic crops gave more preference to major staple food crops. Barahnaja is a traditional orphan crops based mixed cropping system practiced in Himalayan region due to its sustainability and assured crop harvest during erratic weather conditions. This traditional farming method is an exemplary scientific approach to derive innovations with respect to productivity, quality, plant soil interactions and organic agriculture. The main focus of the review is to substantiate the characteristics of the traditional mixed cropping system by describing the advantages of the system and opportunities for scientific innovation towards new knowledge and sustainability.

“…Apart from pollinator-related pollination, common buckwheat is very sensitive to climatic factors, sowing date, photoperiod sensitivity and local agronomic practices that have a strong impact on yield of seeds. Abiotic factors like weather conditions, drought, solar radiation, weeds and available nutrients may affect the development and yield of buckwheat plants [81][82][83]. Some of the important breeding objectives in common buckwheat breeding include stable yield, superior seed quality, lodging resistance, determinate growth habit, easy dehulling, low shattering of seeds, flood resistance, rutin content, low allergenic protein content, good aroma, and pre-harvest sprouting resistance [2,4,5,58,59,84,85].…”

Common buckwheat (Fagopyrum esculentum Moench) and Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.) are sources of many bioactive compounds, such as rutin, quercetin, emodin, fagopyrin and other (poly)phenolics. In damaged or milled grain under wet conditions, most of the rutin in common and Tartary buckwheat is degraded to quercetin by rutin-degrading enzymes (e.g., rutinosidase). From Tartary buckwheat varieties with low rutinosidase activity it is possible to prepare foods with high levels of rutin, with the preserved initial levels in the grain. The quercetin from rutin degradation in Tartary buckwheat grain is responsible in part for inhibition of α-glucosidase in the intestine, which helps to maintain normal glucose levels in the blood. Rutin and emodin have the potential for antiviral effects. Grain embryos are rich in rutin, so breeding buckwheat with the aim of producing larger embryos may be a promising strategy to increase the levels of rutin in common and Tartary buckwheat grain, and hence to improve its nutritional value.
