Abstract
Pigeon pea is an alternative protein plants that grows in tropical and subtropical humid regions, and is well-adapted to resist drought and climate change. Pigeon pea contains 18.8-24% protein and includes amino acids that contribute to balanced and beneficial health. Selecting pigeon pea lines that are effective in germination and the seedling growth stage is an important starting point for improving growth, adaptation and yield. This experiment aimed to assess the seed germination and seedling growth stages of selected pigeon pea lines. A total of 30 lines were chosen from the T9 mixed pigeon pea population to identify strains with early growth capacity before evaluating their growth and yield potential under growing conditions. The results showed that the selected pigeon pea line exhibited high variability in plant height, epicotyl length, hypocotyl length, and root length at 10 days after seeding. Additionally, variability in the selected pigeon pea lines at 30 days after seeding indicated statistically significant differences in plant height, epicotyl length, leaf length, leaf width, number of roots, fresh weight, and dry weight. The correlation coefficient of seedling growth at 30 days after seeding showed that plant height was highly positively correlated with epicotyl length (0.77). Lines P80-1-1, P38-6-1, P04-1-1, and P29-1-1 were identified as promising for further assessment of growth and yield potential in breeding programs.
