The development of a turf‐type bahiagrass could have a remarkable impact on the billion‐dollar turf industry in the south‐eastern United States. The goals of this study were to (i) select bahiagrass genotypes with improved turf attributes and (ii) determine the reproductive mode and seed fertility of selected genotypes. The population included mutants, wild types, hybrids and standard cultivars evaluated at two locations for two years. Morphological variation was observed and clonal repeatability (H2) ranged from 0.27 to 0.90. Flowering was extremely reduced in some mutants, which also exhibited dark green colour, finer texture and reduced canopy height. Cytoembryological observations revealed that diploids reproduced sexually and tetraploids by obligate or facultative apomixis. Genotypes with superior seed fertility were identified, while others were comparable to the standard cultivars. While mutant plants exhibited great morphological variation, the random mutations did not affect their reproductive mode, validating the use of mutagenesis in apomictic species. The high H2 indicated that selection for improved turf attributes could be successfully performed with the advantage of clonal seed propagation.

The review considers the potential environmental risks associated with large scale cultivation of various types of genetically modified forage crops. The results of the study of gene flow in forage grasses occurring in open ecosystems through the dissemination of transgenic pollen by wind and insects at different distances in the stands of forage plants. The necessary conditions for spatial isolation of transgenic and non transgenic samples of forage crops from each other are described. The ecological, biological, and economic value of forage plants, as well as their ecological and environmental functions in agricultural landscapes, including the significant impact they have on the ecological status of ecological communities, contributing to the preservation and accumulation of organic matter in the biosphere are briefly discussed.

Plants having diverse profile in terms of nutrition, availability, tolerance to harsh climatic conditions and possibility of usages as food, forage and biofuel usually referred as Alternative plants. This article will only be focused on the plants having value to reinstate themselves as alternative food crop for the burgeoning population. Indigenous communities across the globe are familiar with a large diversity of flora and fauna that provide sustenance in form of food and medicine. The 'plants for a future' website reveals a list of more than 7000 underutilized species with different values (PFAF website). Most of these plants thrive well on impoverished or marginal soils and dry weather conditions. Millets, Buckwheat, Oats, and Chenopods are coming up as imperative nutritious option. The multipurpose use of Millets, Buckwheat, Oats, Chenopods and Barley coupled with early maturity, low nutrient demand and ability to adapt well to marginal and degraded lands makes them an ideal crop for future sustainable agriculture.
