Biochemical Characterization of Chickpea (Cicer arietinum L.) Genotypes

Abstract

Chickpea (Cicer arietinum L.) is one of the most important legumes in the developed as well as developing countries of the world due to its amazing source of dietary proteins. The present experiment was conducted at Research Farm, RVSKVV, College of Agriculture; Gwalior (M.P.). Forty chickpea genotypes were evaluated during Rabi 2020-21 in Randomized block design with two replications. The samples were analyzed for the analysis of peroxidase, Superoxide Dismutase and some of the key biomolecules like total sugars and proline content. The Total sugar ranged from 16.8 mgg-1 (RVSVT PS-2019- 201) to 24.9 mgg-1 (RVSVT PS-2019- 214), proline varied from 1.49 μmolg-1 (RVSVTK-2019- 104) to 2.91 μmolg-1 (RVSVT PS-2019- 213), superoxide dismutase ranged from 8.2 nmolg-1 (RVSVT PS-2019- 211) to 20.1nmolg-1 (RVSVT PS-2019- 205) and lipid peroxide varied from 1.04 nmolg-1 (RVSVTK-2019-101) to 1.92 nmolg-1 (RVSVTD-2019- 4, RVSVTD-2019- 10). Findings of the present investigation may help to choose better genotypes with useful biochemical contents for future crop improvement.

Screening Chickpea Genotypes against Fusarium Wilt Disease under Controlled Conditions

“…Numerous biotic and abiotic factors contribute to the reduced productivity of chickpea [9][10][11][12][13][14][15][16][17][18]. A comprehensive survey conducted in 1995 across 55 countries revealed the presence of 172 pathogens causing various diseases in chickpea.…”

“…Continuous and exclusive reliance on systemic fungicides for disease control has proven ineffective in achieving complete eradication of the wilt disease from infected areas, even with the development of wilt-resistant pathotypes [21,10]. To address this limitation, the development of resistant chickpea cultivars has emerged as a sustainable alternative approach for disease management [15]. Consequently, the current focus lies on creating wilt-resistant cultivars, conserving genetic diversity, and screening genotypes against specific pathotypes, which are crucial steps towards sustainable farming practices [22].The substantial dependence on intensive fungicide usage as a major agricultural management practice has confirmed inadequacy in reducing the severity of diseases [23][24][25][26][27][28][29][30][31][32], including Fusarium wilt [10,20].…”

Evaluation of Genetic Diversity through D2 Statistic in Chickpea (Cicer arietinum L.)

“…microsperma) is distinguished by its smaller seeds of diverse colors, accompanied by purplish flowers, and contains anthocyanin pigments [8]. The diminished productivity of chickpea is attributed to a combination of different biotic and abiotic factors, as substantiated by recent research [9][10][11][12][13][14][15][16][17][18][19][20].…”
