Root system architecture and seed weight relations in forage pea (Pisum sativum ssp. arvense L. Poir.)

Abstract

Forage pea (Pisum sativum ssp. arvense (L.) Poir.) is an important legume crop for fresh and dry herbage production with high input costs as irrigation and fertilization. Selection and breeding of accessions for improved drought tolerance, water, and mineral uptake efficiency become a necessity, rather than a choice. This study evaluated a set of forage pea accessions for the seedling root system architecture diversity and seed reserve utilization, under controlled conditions. Eight cultivars and an elite breeding line were evaluated for the first time in a plexiglass system. The number and lengths of the roots in each depth zone (0, 5, 10, 15+ cm) were evaluated and significant diversity was identified. The cultivar Livioletta had the highest number of roots and total root length. There was a significant correlation between seed weight, seed reserve utilization ratio, and root system vigor. Accessions with the highest seed reserve utilization had the highest total root length and numbers. Seedling root system vigor seems to be effective in predicting the fate of the accessions through maturity. The results suggested a possibility of “seedling root selection” for forage crop breeding.

Comparative Evaluation of Salicylic Acid (SA) and 2,4-Dichloro-6-{(E)-[(3methoxyphenyl)imino]methyl} Phenol (DPMP) on Growth and Salt Stress Tolerance in Forage Pea (Pisum sativum L. arvense)

“…Legume forage crops have a soil nitrogen recovery advantage compared to forage crops from the Poaceae family due to nitrogen fixation ability (Den Herder et al, 2010). Genetic diversity (Demirkol and Yılmaz, 2019), common root trait diversity (Acikbas et al, 2022), yield and yield components (Uzun et al, 2012;Ateş and Tekeli, 2017;Tan and Kadıoğlu, 2018), and PEG induced osmotic stress (Bektas, 2022) responses of forage pea were previously reported. In a study conducted by germination characteristics of forage pea were also evaluated.…”

Evaluation of variation in seedling root architectural traits and their potential association with nitrogen fixation and agronomic traits in field pea accessions

“…Genotypic differences among pea accessions for lateral root number have been observed, with suboptimal root growth media temperatures causing decreased root growth and developmental processes (Balliu & Sallaku, 2021). Acikbas et al (2021) studied RSA variation in forage pea accessions and reported positive correlations between seed weight, seed reserve utilization, and root system vigor. Kraft and Boge (2001) highlighted the correlation of root architectural traits such as greater number of lateral roots, high RD, and root dry weight with Fusarium root rot resistance.…”

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

“…Forage pea ( P. sativum ssp. arvense L.) is a significant legume crop for fresh and dry grass production as well as an alternative to barley and vetch in animal nutrition [ 1 ]. Field-pea ( P. sativum ssp.…”

“…Forage pea plays an important role in meeting global forage demand. The annual green herbage production of forage pea is about 21 million tones on 2.7 million ha area globally, and 452.776 tons on about 24 thousand ha area in Turkey [ 1 ]. Although Turkey is the genetic pool and center of origin of many cultivated and wild forage crops, the production of high-quality hay remains a key challenge in Turkey compared to the global production scale due to insufficient forage cultivation [ 5 ], while the average productivity of forage peas in Turkey is very low.…”
