AbstractPerennial grain crops would address many agricultural problems, including soil erosion, nutrient loss and pesticide contamination. Doubts about the possibility of perennial grain crops rest upon two assumptions: (1) that the relationship between yield and longevity is a fixed function that cannot be influenced by selection, mutation or environmental changes; and (2) that yield and longevity trade off in a bivariate manner to the exclusion of all other traits. These assumptions are consistent with the phenotypic trade-off model, but recent research suggests that a quantitative genetic model is a more appropriate approach to trade-offs. In the quantitative genetic model, environmental and genetic changes can result in increases in two traits simultaneously even when a trade-off, or negative correlation, exists between the two traits. Empirical evidence that the trade-off between perenniality and reproductive allocation is not fixed comes from wild, herbaceous perennials that can produce more than 2000 kg seed ha−1 in the temperate zone, and herbaceous perennial crops that produce on average 8900 kg fruit ha−1 in the tropics. Ecological literature suggests that most perennials produce small amounts of seed relative to their vegetative growth not as a physiological absolute, but rather as a result of natural selection in a stable, competitive environment favoring longevity. By selecting strongly for seed yield in a population of perennial plants, the plant breeder can likely achieve that which is rare in nature—a high seed-yielding perennial plant. The same general methodologies that have allowed annual grain breeders to increase grain yield and push many combinations of negatively correlated traits to levels of expression not seen in nature are available to the perennial grain breeder. Perennial grain breeders are integrating ecological principles and traditional plant breeding methods in their efforts to develop perennial grain wheat (Triticum spp.), sorghum (Sorghum spp.), sunflower (Helianthus spp.), Illinois bundleflower (Desmanthus illinoensis) and rice (Oryza spp.).

Abstract The article presents an overview of perennial grain crops, gives a comparative characteristic of annual winter wheat and perennial grain crops such as Trititrigia (Trititrigia cziczinii Tsvelev), Thinopyrum intermedium, perennial rye (Secale cereale L) and perennial sorghum (Sorghum x derzhavinii Tzvel.). The study aims to consider the main perennial crops grown in Russia and in the world, to compare their quality indicators, sowing agrotechnical requirements, cultivation conditions, yields, and to justify the choice of perennial crops that meet the needs and climatic conditions of the Rostov region. Presented is the generalized information on the grain quality changes during maturation, ripeness phases of grain crops are considered. Based on the review, the optimal ripeness phases, at which it is advisable to harvest are presented. Literature review showed that in the phase of lactic (мoлoчнaя cпeлocть) and wax maturity (вocкoвaя cпeлocть) wheat grain contains the greatest amount of basic nutrients. It was found that perennial crops have a positive effect on the state of the soil: prevent its erosion and depletion; there is an accumulation of carbon, soil methane CH 4. Comparative characterization of perennial crops with annual crops shows increased protein content - on average 2-3% higher. Also considered are the green mass quality indicators of perennial crops as a source of nutrients in the feed-production technology.

Methods of disease management used in annual grain crops, especially cultural practices designed to disrupt the disease cycle of a particular pathogen, will not necessarily be applicable to perennial grain crops. Resistance to multiple pathogens, therefore, will clearly be important in disease management. The objective of this research was to evaluate disease resistance in 10 perennial grain accessions (one to two accessions of each: perennial wheat (Thinopyrum sp. × Triticum aestivum), intermediate wheatgrass (Thinopyrum intermedium), perennial rye (Secale montanum), hexaploid triticale (Triticum turgidum × S. montanum), octoploid triticale (Triticum aestivum × S. montanum), tetraploid perennial rye (Secale cereale × S. montanum), and tall wheat-grass (Thinopyrum ponticum)) to tan spot (caused by Pyrenophora tritici-repentis), take-all (caused by Gaeumannomyces graminis var. tritici), wheat streak mosaic, and barley yellow dwarf, four important diseases of the Great Plains. Several of the grasses were resistant to tan spot, barley yellow dwarf, and wheat streak mosaic. Indeed, the wild grasses and perennial donors T. intermedium (including BFPMC1), T. ponticum, and S. montanum, in addition to Permontra, a tetraploid perennial rye, were highly resistant to all three diseases. Additionally, the remaining grasses tested were also more resistant to tan spot than the susceptible wheat control. However, none of the 10 grass accessions appeared highly resistant to take-all, and substantial losses in biomass were observed, although such effects may be moderated under field conditions due to the potential for take-all decline in perennial plantings.

This chapter considers four ideas—suggested by Wes Jackson and Jon Piper in the classic paper, “The necessary marriage between ecology and agriculture”—for how agriculture might attempt to mimic nature: perennial grain crops; reliance on only local sources of nutrients; polyculture or intercropping (that is, deploying crop diversity as mixtures, as in many natural ecosystems); and reliance on biodiversity to control pests. The chapter examines each of the proposals in light of the conclusion that copying landscape-scale patterns from natural ecosystems is not necessarily a good idea, arguing that all of them are representative of many self-styled “agroecologists.” It also discusses complementarity in crop mixtures, specifically spatial complementarity, temporal complementarity, and nutritional complementarity.

Although agriculture has traditionally been primarily the concern of the world, it now plays an increasingly important role in how we meet challenges—international food security, environmental protection, climate change, energy supply, economic sustainability, and human health. With population growth and environmental deterioration, the attention about food security and sustainable agriculture is on the increase, and the status of ecological agriculture comes into prominence. Perennial grain crops would address many agricultural problems as well as substantial ecological and economic benefits, which can provide multiple ecosystem services essential for sustainable production more effectively than production systems based on annual crops, such as protecting against soil erosion, conserving water and nutrients, storing more carbon below ground, and building better pest tolerance. This paper presents some of advantages of perennial grain crops as a new option for the food security and ecoagriculture, as well as prospects the significant utilization of perennial crop on sustainability of agriculture and environment in the future.

Perennial grain crops have been proposed as environmentally sustainable alternatives to annual grain crop systems that currently dominate the world's major breadbaskets. Proponents emphasize the potential of perennial grains to mimic natural systems and thereby reduce soil erosion, nutrient losses, and degradation of soil quality although need for adequate grain yield is also recognized as a prerequisite for success. Here we assess progress since 2005 (16 y) towards development of perennial grain systems with sufficient productivity to be seen as competent alternatives to annual wheat on the prairies and plains of North America and Australia. Based on reports published in refereed journals, we see little evidence that yield of Intermediate Wheatgrass or perennial wheats have improved to the point they are viable alternatives. Slow progress is attributed to lack of minimum grain yield targets for economic viability, lack of designated target regions where perennial grains are most likely to be competitive against annuals, selection methods that focused on components of yield rather than yield per se (i.e. on an area basis), and relatively small R & D investment compared to resources given to genetic and agronomic improvement of major annual grain crops. Given current status, we conclude that perennial grains will require substantial R & D investment and several decades if they are to achieve sufficient yield potential and yield persistence to become more than a niche crop for upscale health food markets in wealthy countries.
