Different research institutes belongs to Ministry of Agriculture and collaboration with different universities selected promising mulberry genotypes mostly from Morus alba (white mulberry), Morus nigra (black mulberry) and Morus rubra (red mulberry) through conventional selection breeding studies.
Species, seed formation, fruit weight, SSC (Soluble solid content), titratable acidity, juice yield and pH in the mulberry fruits: Among 34 mulberry genotypes, 28 genotypes were belonging to Morus alba, 4 genotypes belongs to Morus nigra and 2 genotype belong to Morus rubra (Table 1).
Lale and Ozcagiran (1996) and Ozdemir and Topuz (1998) indicated that SSC content was the highest in Morus alba genotypes compared to Morus nigra and Morus rubra.
According to 3 years average values, the pH of genotypes were the highest in Morus rubra genotype 'Mersin mor dut' as 5.
All black mulberries (Morus nigra), except Hikmet 1 had the higher fruit juice yield ratio than Morus alba and Morus rubra genotypes.
