Determination of Flower, Pod and Seed Characteristics Related to Yield Components in Forage Pea Genotypes

Abstract

In this study which was carried out during the 2015 summer season in Eskişehir, the flower, pod and seed characters attributed to yield components were investigated in 12 forage pea genotypes. They showed significant differences in terms of agronomic and morphological (flower, pod, and seed) traits. The highest fresh hay yield with 2171 kg/da and plant height with 106.6 cm were obtained from Populasyon-1. Crackerjack had lower values in some flower traits such as, whereas the higher values of pod and seed traits were obtained from cv. Rose. In addition, Population-1 included in the higher value group for standard petal width, keel petal length, calyx tube and teeth lengths, and flower length. Although cluster analysis did not reflect agronomic traits, the clustering resulted in four groups. The first group consisted of Özkaynak 1, 2, and 3 and Taşkent, Töre, and Population-2, which were the standard petal colour violet, light, and dark violet. Population-1 had both violet and white standard petal; however, it was included in the second group together with white-flowered Ulubatlı and Ürünlü according to cluster analysis. While Rose and Gölyazı were in the third group, Crackerjack was in the fourth group alone. There was a highly significant positive correlation between fresh hay yield and both standard petal width and length and flower length. Consequently, a hopeful result for summer growing in Eskişehir condition was obtained from Population-1. It was suggested that some flower characters can be used for pre-selection of yield-related traits in the evaluation of genetic diversity of pea germplasm through morphological trait.

Determination of Physical Properties, Color Properties, Mechanical Behavior and Germination Parameters of Three Different Forage Peas Cultivars

“…It has been determined in many studies that there is a difference in shoot age weights between cultivars. Okcu et al 2005 used the same cultivars used in our study, Avci et al 2020, the mean fresh shoot weights were between 199 to 243 mg/plant, and Küçüközcü and Avci 2020, in their research including similar cultivars, determined the mean fresh shoot weight as 132.06-161.16 mg/plant. Dumanoglu et al 2021 In the light of the data obtained in their research, reported that species and cultivars with high shoot weight are an important criterion in the evaluation of forage plants used in animal nutrition, and it is important in terms of providing a good genotype preference to scientists, especially in breeding studies.…”

“…While the germination rate of the Töre cultivar was the lowest at 93.33%, the seeds of the other two cultivars were all germinated and a germination rate of 100% was obtained. İt has been reported in many studies that the mean germination rate of forage pea seeds is ≥95% (Okcu et al 2005;Kücüközcü & Avci, 2020;Avci et al 2020;Dumanoglu et al 2021). The vigor index value, which is another examined parameter, was realized as 16.82 on mean, and the lowest vigor index value was obtained from the Töre cultivar, while the highest was obtained from the Özkaynak cultivar.…”

“…Okcu et al (2005) have determined the root lengths of Bolero, Sprinter, and Utrillo cultivars as 13.99 cm, 11.69 cm and 3.19 cm, respectively. Avci et al (2020) determined that the mean root lengths of 2020 are between 7.03-8.00 cm. Demirkol et al (2019), investigated different salt doses in a forage pea genotype, which they considered promising, and they found the radicula length to be 6.24 cm in the control application.…”

“…Reis. Avci et al 2020, determined the mean dry shoot weight of 2020 between 18.8-20.1 mg/plant and determined that the effect of these values on cultivars was not statistically significant. The mean fresh shoot length of the cultivars examined in the study was 11.40 mm and this value did not make any statistical difference on the cultivars.…”
