“…In the 2 nd year of use, the cultivar mixture was more productive than the perennial ryegrass single cultivars 'Raminta' and 'Verseka'. Lowry et al (2020) have reported that the effects of functional trait diversity within cultivar mixtures cannot always be predicted by the performance of cultivars in single-species crops. This may also depend on the synergy between varietal traits as well as on management practice (Tubritt et al, 2021).…”

“…Recent studies have focused on single perennial ryegrass cultivars, but little research has been done on cultivation possibilities and prospects for growing mixtures of perennial ryegrass cultivars (Lowry et al, 2020;Tubritt et al, 2021). The competitive dynamics of the mixture of perennial ryegrass cultivars during the two growing seasons showed more pronounced differences in the 2 nd year of sward use.…”

“…Cultivar and/or species mixtures optimized with respect to functional trait diversity have been discussed recently as being highly important for securing grassland productivity (Mahaut et al ., 2019; Lowry et al ., 2020). One principal question of the current study was whether cultivars of perennial ryegrass representing important functional traits affect forage quality in (i) pure stands and (ii) in mixtures with white clover or white clover and forbs.…”

“…Results on the performance of single cultivars, however, do not provide information on their performance in mixtures. It was reported recently that maximizing the functional-trait diversity of perennial ryegrass cultivar mixtures, rather than cultivar richness itself, promoted biomass production (Lowry et al ., 2020). Designers of herbage seed mixtures are now starting to combine cultivars in ways that increase functional trait diversity.…”

Effects of functional traits of perennial ryegrass cultivars on forage quality in mixtures and pure stands

Plant breeding has brought about improvements in the herbage yield potential, forage quality and functional traits of perennial ryegrass (Lolium perenne L.). Under conditions of low external inputs, grassland swards based on perennial ryegrass often contain dicotyledonous species (legume and non-legume). Cultivar-specific functional traits such as growth form or phenology affect the competitive ability and yield in mixtures, but the extent to which cultivars with different functional traits affect forage quality in mixtures compared with pure stands is unknown. Therefore, we analysed four perennial ryegrass cultivars, each representing a combination of two functional traits with respect to phenology (early v. late heading) and growth form (upright v. prostrate) on forage quality, in a field experiment over 5 years. Each cultivar was grown in binary-mixtures with Trifolium repens L., as four-species mixtures with Taraxacum officinale L. and Plantago lanceolata L., and as grass monocultures. The effect of functional traits was dominant in the primary growth and persisted in pure stands but not in the mixtures from the third year onwards. Prostrate cultivars allowed the development of a greater proportion of clover and forbs within the mixtures, resulting in increased protein and energy and reduced fibre contents. In mixtures, forage quality was generally higher in the last regrowth. In conclusion, the indirect effects of growth form on forage quality due to modifications of botanical composition were more important than direct effects on forage quality.

Genotype by environment analysis on multi‐canopy cropping system in rice: Effects of different types of flag leaves

Breeding rice (Oryza sativa L.) for the multi‐canopy (MC) cropping system is one of the novel ideas for increasing production. This system involves combining rice genotypes with different plant heights to form stratified panicles and flag leaves. This study aimed to elucidate the effects of different characteristics of flag leaves of tall plant genotypes on yield and agronomic traits in MC cultivation. The study was conducted from May 2020 to January 2021 at the IPB University Experimental Station at Babakan, Bogor, West Java, Indonesia. The genetic materials were seven rice inbred lines of F9 from an ongoing breeding program at IPB University, consisting of four tall genotypes with different flag leaf characters, namely IPB187‐F‐90‐1‐1 (ordinary, short flag leaf); IPB189‐F‐19‐2‐1 (V‐shaped, medium‐length flag leaf); IPB187‐F‐40‐1‐2 (V‐shape, narrow, half rolled, and long flag leaf); IPB189‐F‐8‐1‐1 (wide, long flag leaf), and three short genotypes, namely IPB193‐F‐19‐1‐3, IPB187‐F‐69‐2‐3, and IPB189‐F‐13‐1‐1. The experiment was carried out in four environmental conditions, namely: (a) monoculture and (b) MC, 2020 dry season, (c) monoculture, and (d) MC, 2020/2021 wet season, using a randomized complete block design with three replications. The results showed that the genotype × cropping system interaction significantly affected total yield (p < .05). The MC cropping system produced a higher average yield (6.65 t ha–1) than the monoculture (6.01 t ha–1) across the two seasons. The genotype with V‐shape and medium‐length flag leaf gave the highest yield in MC. This study substantiated the potential of breeding rice varieties suitable for the MC system.
