Disentangling potential genotypes for macro and micro nutrients and polymorphic markers in Chickpea.

Area of Science:

• Agricultural Science
• Plant Genetics
• Nutritional Science

Background:

• Chickpea (Cicer arietinum L.) is a vital legume crop, but its nutritional diversity needs enhancement for breeding programs.
• Identifying genetic resources for macro- and micro-nutrient traits is crucial for improving chickpea's nutritional value.

Purpose of the Study:

• To assess nutritional diversity in chickpea genotypes.
• To identify novel genetic resources and develop molecular markers for breeding improved chickpea varieties with enhanced nutrient content.

Main Methods:

• Nutritional and phytochemical analysis of nine chickpea genotypes.
• Bioinformatic analysis of EST sequences to mine for novel SSRs (Simple Sequence Repeats).
• Primer design, PCR amplification, and analysis of polymorphism using Jaccard's similarity and UPGMA clustering.

Main Results:

• Significant differences (p < 0.05) in nutritional properties were observed among genotypes.
• Five novel EST-SSR markers (ICCeM0012, ICCeM0049, ICCeM0067, ICCeM0070, ICCeM0078) and existing markers (SVP series) were identified.
• Six newly designed primers showed polymorphism with a median PIC of 0.46, indicating moderate diversity.

Conclusions:

• Specific chickpea genotypes (PUSA-1103, K-850, PUSA-1108, PUSA-1053) and novel EST-SSR markers are valuable genetic resources.
• These resources can be utilized to broaden the germplasm base for chickpea breeding strategies focused on macro- and micro-nutrient enhancement.
• The findings provide a foundation for developing improved chickpea varieties with superior nutritional profiles.
