“…This was especially evidentc for tetraploids due to their higher content of water. Some investigations have shown that forage yield of tetraploid can be higher more than 50% in cases when DM yield is higher only by up to 10% (Leto et al, 2004;Zuk-Golaszewska et al, 2010). Our results confirm this relationship, as forage yield of tetraploid genotypes was higher by 12.3%, compared that of with diploid genotypes, while DM yield was higher by only by 6.5%.…”

The research was carried out in 2003-2011 at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry. The fresh forage, dry matter (DM) and seed yields of red clover diploid and tetraploid populations and cultivars were determined. In total 58 diploids and 35 tetraploids were evaluated during four cycles in the study period. The average DM yield of diploids was 16.6 t ha -1 and of tetraploids was 17.8 t ha -1 . The tetraploid average DM yield surpassed that of diploids by only 6.5%. The seed yield was very low over the period. The average seed yield of diploids was 110.4 kg ha -1 . The average seed yield of tetraploids was 94.9 kg ha -1 . The diploid average seed yield was higher than that of tetraploids by 16.3%. The highest negative impact on seed yield was due to wet weather in the seed harvest year, which was favourable for development of diseases on above-ground plant parts. The study showed that tetraploid red clover had no significant advantage over diploid red clover in DM yield under Lithuanian conditions. Variation in seed yield showed that production of diploid red clover seed is less problematic. It seems that only directed disease resistance breeding can improve seed yield as well as forage yield of red clover.

“…The usual stand life for red clover production is no longer than three years, with few cuts and in one growing. Under ecological conditions of West Croatia had achieved average annual forage yield from 9.18 to 10.8 t ha -1 (Leto et al, 2004). It is a perennial, diploid (2n = 2x = 14) and outcrossing species with a gametophytic selfincompatibility system (Taylor, Quesenberry, 1996).…”

The main objectives of this study were 1) to estimate variation in yield, forage quality and morphological traits of newly developed red clover (Trifolium pratense L.) breeding populations of different origin, 2) to compare their yield potential with foreign cultivars, 3) to determine the relationship between studied traits and 4) to identify and select the most promising populations for future breeding work. Eight red clover breeding populations of different origin (OPCD-2, RCOP-1,3,4,5,6,7,8 created within the framework of the forage crops breeding program at the Agricultural Institute Osijek, Croatia) and eight foreign cultivars ('Liepsna', 'Kamaniai', 'Nosovskij 5', 'Pallas', 'Astred', 'Redquin', 'Milvus', 'Amos') were evaluated for thirteen morpho-agronomic and forage quality traits. Field experiment was designed as a randomised complete block with three replications over two consecutive years (2008 and 2009) at the Agricultural Institute Osijek, Croatia. The studied breeding populations/cultivars of red clover significantly varied in yields of green mass and dry matter, plant height, number of internodes, density of hairs, width and length of central leaflet, shape of medial leaflet, leaf to stem ratio, content of crude protein and relative feed value. Croatian breeding populations RCOP-3, OPCD-2 and RCOP-1 had significantly higher total yields of green mass (from 98.50 to 111.82 t ha -1 ) and dry matter (from 22.61 to 25.64 t ha -1 ) compared to the observed yields of other populations and foreign cultivars of red clover, which indicates their high genetic potential for yield. Besides the high forage yield, those breeding populations achieved favourable values of quality and other analyzed morphological traits, and they are representing valuable germplasm for further selection work and improving of our breeding program and/or application for plant cultivar registration. Positive correlations were found between forage yields and plant height, number of internodes and between width and length of central leaflet, and these properties were positively correlated with each other. Most quality traits were in negative correlation with yield and other observed morpho-agronomic traits.

“…In addition, the tetraploid germplasm in summer drought, typical for the plains of Northern Bulgaria, stops growing and does not compensate for its limited vegetative growth, despite the excellent moisture guarantee in the late summer, as well as in the spring the next growing season. The conclusion about reduced productivity and persistence of tetraploids on dry conditions or uneven distribution of rainfall during vegetation is also supported by Leto et al (2004). (Loucks, 2017).…”

From the first to third growing season in the field test carried out at the Experimental Station of Soybean (Pavlikeni, Bulgaria) was observed 12 genotypes of red clover, including two Bulgarian diploid varieties Nika 11 (standard) and Sofia 52, four local diploid populations and next six foreign tetraploid varieties, i.e. Kvarta, Astur, Carbo, Elanus, Fregata and Larus. The goal of study was to determine the effect of ploidity level of the varieties as well as the effect of adaptive variability of local populations on fresh mass yield, dry mass yields and their persistence in an agro-ecological area with lower summer moisture assurance for red clover. The highest total dry mass yield was observed for varieties Sofia 52 (2n), Nika 11 (2n), Kvarta (4n) and Astur (4n). The productivity of tetraploids Kvarta and Astur strongly varies depending on the season and the year, as well as the age of sward. According to the obtained comparative production data for cuts and years, the tetraploid germplasm has a stronger adaptation to the limiting moisture. In summer drought, typical for the plains of Northern Bulgaria, tetraploids stop growing and do not compensate for their limited vegetative growth, despite the excellent moisture guarantee in the late summer, as well as in the spring the next growing season. Local wild-type germplasm of the species is characterized by a rapid development and lower yield of fresh and dry forage mass compared to the diploid standard when growing in conditions of optimum moisture but relatively high productivity in the dry conditions of the summer months. The differences in the genotypic productivity response under dry conditions reported in this experiment also suggest that the abiotic limit studied can be successfully responded by the genotype factor.
