“…The property of type II diabetes-related enzyme inhibition capacity in this crop has recently been revealed in raw and different processed forms of seeds [19,20]. In recent times, genetic improvement programs for desirable agronomic features particularly high yield and low antinutritional factors including neurotoxin ( -ODAP) have gained momentum in grass pea with development of robust mutation genetic and cytogenetic stocks [21][22][23][24][25][26][27][28][29]. However, like many other pulses, grass pea faces diverse types of abiotic stresses such as drought, salinity, metal, and weed-induced toxicity [30][31][32][33].…”

Response of six improved grass pea genotypes to prolonged salinity stress was investigated on seedlings grown in pot experiment using 150 mM NaCl up to 60 days of growth after commencement of treatment (DAC). NaCl exposure significantly reduced growth potential of varieties PUSA-90-2 and WBK-CB-14, but no such effect was observed in varieties B1, BioL-212 and in two mutant lines LR3 and LR4. A time-bound measurement at 15, 30 and 60 DAC revealed significant reduction in plant dry matter production, orchestrated through abnormally low capacity of leaf photosynthesis accompanied by low K + /Na + ratio and onset of oxidative stress in all six genotypes at 15 DAC and the extension of the phenomena in PUSA-90-2 and WBK-CB-14 to 60 DAC. High superoxide dismutase (SOD) activity coupled with low ascorbate redox and declining ascorbate peroxidase (APX) and catalases (CAT) levels led to abnormal rise in H 2 O 2 content at reproductive stage (30 DAC) in the latter two genotypes, consequently, resulting in NaClinduced oxidative damage. H 2 O 2 level in the rest of the four genotypes was modulated in a controlled way by balanced action of SOD, APX and CAT, preventing oxidative damage even under prolonged NaCl-exposure. Enzyme isoforms were involved in regulation of foliar H 2 O 2 -metabolism, which was critical in determining As tolerance of grass pea genotypes.

“…Quantitative variation in these compounds has been linked to phenotypic (seed hilum color) and molecular markers, which should assist with the breeding of lines having very low activities of these anti-nutrients Gutierrez et al, 2004). In grass pea, major breeding efforts have aimed at reducing the β-ODAP content, resulting in the release of a number of cultivars with low β-ODAP (Kumar et al, 2011). However, this strategy of prioritizing the reduction of β-ODAP content in breeding programs is under debate today (Vaz Patto and Rubiales, 2014).…”

“…The seeds analyzed under Austria conditions using the Ceora variety had a β-ODAP content of 0.1 mg/g. [2,26] However, when this variety was grown under Antalya conditions, the β-ODAP content was 3.52 mg/ g. This situation is thought to result from changing environmental conditions or genetic segregation, caused by foreign pollination which exists at a rate of 2-5% in Lathyrus species. Vaz Patto et al [3] and Jiao et al [27] previously reported that the L. sativus plant has a wide range of variability in β-ODAP content.…”

Lathyrus sativus L. is considered one of the most promising calorie and protein sources for the vast, expanding populations living in drought-prone and marginalized areas of the world. This study was conducted to determine the β-N-oxalyl-L-2,3-diaminopropionic acid (β-ODAP), L-homoarginine, and asparagine content of a total of 173 Lathyrus sativus L. genotypes, of which 93 were collected under natural conditions in Antalya. The β-ODAP, L-homoarginine, and asparagine content of Lathyrus sativus L. genotypes ranged from 1.55 to 20.8 mg/g seeds, 1.35 to 11.64 mg/g seeds, and 0.59 to 5.22 mg/g seeds, respectively.
