A Comparative Study on Fruit Characters, Germination and Seedling Growth in Some Monoembryonic and Polyembryonic Mango Genotypes

The investigations were carried out to compare the fruit characters, germination behaviour and nursery performance of twelve polyembryonic and ten monoembryonic genotypes. Wide variation was observed in fruit and stone characters like weight, volume, length, breadth and circumference in polyembryonic genotypes. The monoembryonic genotypes had higher pulp content whereas polyembryonic genotypes had more thick peel and less pulp percentage which reflects on the poor acceptability of polyembryonic genotypes. Based on the nursery performance, the genotypes were classified with respect to their vigour for being tried as rootstocks. Among the polyembryonic genotypes, Starch, Peach and Kurukkan were classified as less vigorous genotypes. In monoembryonic genotypes, Amrapali, Langra and Chausa were grouped as less vigorous genotypes.
