Forage pea (Pisumsativum var. arvense L.) landraces reveal morphological andgenetic diversities

Abstract

The objective of this study was to assess morphological and genetic diversities of 48 forage pea landraces collected from different locations at different altitudes in Turkey. Morphological, quality, and yield features were determined for the landraces and three control cultivars in three subsequent years. Genetic diversities of the landraces and cultivars were also monitored using microsatellite (SSR) markers. Our results revealed that the features of landraces are significantly different. The hay weights and the relative feed values were found to be significantly affected by altitude, with the landraces generally showing significantly higher hay weight and relative feed values at lower altitudes (P < 0.05). At the genetic level, 32 SSR primers led to distinct placement of one of the samples into a different clade of the dendrogram, showing that it is genetically different from the other 47 samples. This genetically different landrace had the highest forage value, suggesting that it shows higher prime forage features than the cultivars and the other landraces. Moreover, altitude and generally flower color were found to be important factors affecting the genetics of the landraces, as the landraces having white flowers or collected at similar altitudes were clustered well in the dendrogram. The results of this study reveal that the morphological and genetic diversities of forage pea landraces collected from different locations at different altitudes show variations. Such information could be used to develop forage pea landraces with improved characters that can be used in hay management.

“…While no change was observed in ADF and NDF in P1 and P4 (Figure 3, 4), P2, and P3 showed increases under stress condition. Increased ADF rates decreases the forage quality due to the increase of the nondigestible fiber content (Demirkol and Yilmaz, 2019). Similar decreases in crude protein ratio and forage quality under phosphate limited conditions were reported in phosphate-sensitive narbon vetch (Turk et al, 2007).…”

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

“…Our results demonstrated that there was an enormous variation in the available forage pea genotypes. In Turkey, forage pea genotypes collected from North East Anatolia and Eastern Black Sea regions indicated immense variation regarding agro-morphological characteristics similar to these findings (Tan et al, 2012;Tan et al, 2013;Demirkol and Yılmaz, 2019). Plant heights and dry matter yields of forage pea genotypes ranged from 68.8 to 102 cm and 486 to 677 kg/da, respectively according to Tan et al (2013).…”

“…Morphological characterization is the first step in the identification and classification of germplasm (Smith & Smith, 1989). In the studies conducted by, Tan et al (2012), Tan et al (2013) and Demirkol and Yılmaz (2019) compared forage pea genotypes collected from different locations with commercial varieties to identify promising local ecotypes, there were important differences between the genotypes in terms of the agro-morphological characters. Ali et al (2007), Nisar et al (2008), Gatti et al (2011), Nisar et al (2011 and Umar et al (2014) found that the genetic diversity in peas and their relationship with the yield components were mostly based on agromorphological characters.…”

SSR-Based Molecular Identification and Population Structure Analysis for Forage Pea (Pisum sativum var. arvense L.) Landraces

“…Recently, Demirkol and Yilmaz [ 15 ] studied the genetic diversity of 48 forage pea landraces collected from the East Black Sea Region in Turkey. Forage pea landraces were collected using the criteria of the International Union for the Protection of New Varieties of Plants (UPOV) and used 32 SSR markers.…”
