Abstract

Seed qualitative characteristics and their effects on seed GERMINATION are affected by genotype and soil moisture conditions in the field and the time after harvesting. The experiment was carried out as factorial split-plot design in randomized complete with three replicates in laboratory condition. The main plots were combination of 4 different IRRIGATION REGIMES (I1, I2, I3=eight, six and four hours every other day, respectively and I4=four hours per day) and 4 different genotypes [Danial (V1), Line6 (V2), Champa (V3), Red Anbori (V4)]. Five post-harvest interval times (0, 20, 40, 60 and 80 days) were considered as subplots. The results showed that high yielding genotypes were superior in comparison with local genotypes because of less shell percentage, higher 1000 seeds weight and bigger embryo. Seed qualitative characteristics affected by genotype, IRRIGATION REGIMES and the time after harvesting. IR2 was the best treatments in the GERMINATION percentage (77%), length of shoot (8.9cm) and seedling dry weight (34mg). Line 6 had the highest seed GERMINATION (82%), root length (8.7cm) and seedling dry weight (43.6mg). The highest shoot length (9cm) grew up 60 days after harvesting. By applying every IRRIGATION REGIMES, line 6 after the 80-day time after harvesting had the highest seed GERMINATION.
