“…This is consistent with existing research on U.S. cotton cultivars (Burke, 1990;Mahan, 2000;Wanjura et al, 1990Wanjura et al, , 1992. Although genotypic variation in chlorophyll fl uorescence recovery rates can be observed in G. hirsutum between genotypes of diff erent thermotolerances (Snider et al, 2010) and in other species (Karlsen and Steiner, 2007), the Australian cultivar Sicot 70BRF gave similar results to the historically studied U.S. cultivars Paymaster 145 and Paymaster HS26.…”

A plant-based thermal optinnum approach to irrigation scheduling provides potential benefits in that water applications are scheduled on the basis of plant response to vi/ater status. Such irrigation systems require a defined thermal optimum for the crop and while such optimum values have been identified for cotton {Gossyplum hirsutum L.) cultivars in the United States, tinere is no information of this type for cultivars common in Australian production. This paper outlines a threefold approach to determining the optimum temperature (T^^p,) of the commercial Australian cotton cultivar Sicot 70BRF in an Australian production system. It combines the use of a laboratorybased fluorescence assay, field-based net C assimilation rate (A) and stomatal conductance to water vapor (g J, and canopy temperature {TJ-yield relations. The fluorescence assay showed a T^pt between 28 and 30°C while leaf gas exchange rates peaked at a leaf temperature (T,) of 29°C. The T^-yield relations peaked at 26°C, with yield reductions observed when T^ > 28°C. We conclude the T^p, of the Australian upland cotton cultivar Sicot 70BRF to be 28 ± 2°C. This 1^ J will provide valuable information for use in thermal optimum irrigation scheduling systems.

“…Zhao et al (2006) found the amount of genetic similarity (GS) averaged between 0.51 and 0.63 within this set of A. capillaris, suggesting that this material may be a source of genetic diversity. Karlsen and Steiner (2007) used random amplifi ed polymorphic DNA markers to assess the genetic diversity in a set of 18 Scandinavian colonial bentgrass accessions. Similarity ranged from 0.23 to 0.84, and based on marker clustering, three major groups were formed.…”

It is estimated that there are between 150 and 200 species of Agrostis, and interspecific hybridization is a proven method for improving cultivated Agrostis species. The pool of publicly available Agrostis germplasm, available through the National Plant Germplasm System, represents 17% of the total number of Agrostis species. The total amount of genetic diversity of this germplasm should be assessed to determine if there are novel sources of stress resistance. Agrostis species have a base haploid chromosome number of seven and can range in ploidy from diploid (2n = 2x = 14) to dodecaploid (2n = 12x =: 84)

The modern concept of crop production development, focused on the biologization of agriculture, provides for an increase in the diversity of plant species and varieties used, most adapted to the conditions of specific areas of their use and providing maximum ecological and economic effect. To do this, it is necessary to intensify the selection and seed-growing work on the breeding of new varieties of herbs with the simultaneous expansion of species representation. Representatives of the genus bentgrass (Agrostis L.) have a high biological potential, cenotic activity and productive longevity when creating artificial agrocenoses for various purposes. The article analyzes the features of the taxonomic classification of the genus Agrostis, biological features of the most promising bentgrass species for economic use. In the State Register of Breeding achievements approved for use in the territory of the Russian Federation as of 2023, 8 varieties of giant bentgrass (A. gigantea Roth.), 9 — creeping bent (A. stolonifera L.) and 7 — brown top (ordinary) (A. tenuis Sibth.). The last two types are mainly used to create lawns for various purposes. The most promising Agrostis species for establishing agrocenoses for fodder use, primarily in grassland farming in the Non-Chernozem Zone, is giant bentgrass. The article presents the results of breeding work of the Federal Scientific Center "VIK named after V.R. Williams" on the development of new varieties of giant bentgrass.
