Morphological evaluation of Pyrus genotypes of Kaghan Valley, Pakistan through quantitative parameters

In the present study, 14 genotypes of Pyrus were evaluated and compared for quantitative parameters viz. Petiole length, Leaf Area, Pedicle length, Fruit length, Fruit width and Fruit weight with the help of local names belonging to Kaghan Valley, Pakistan. The study revealed that the genotypes are highly significant with respect to above parameters except leaf area. Mean value shows that genotypes Kushbago, Atti Bating and Shardi Tanchi have maximum value while genotypes Black batangi and Glass batangi have minimum value while all others have intermediate values with respect to petiole length. For Pedicle length, genotypes Black batangi, Brown batangi, Nak Hard Skin, Shardi tanchi have minimum value (ranges 15-20 mm), genotype kushbago has maximum (65.5 mm), Tanchi and Glass batang have similar (55.8mm) values and all others ranges from 21.5-30 mm. Similarly for fruit length, genotypes Glass Batang has highest value fallowed by genotypes Kado and China batang while genotypes Black Batangi, Golden Batangi and Shardi have minimum value. For fruit weidth, genotype Chiana batang has highest value, genotypes black batangi, golden batangi and Shardi tanchi have the lowest value while genotypes Kado and Glass batang have similar values and all others genotypes have values ranges from 35.17-46.1 mm. For fruit weight, genotypes China and Glass batang have maximum value, followed by genotypes Kado, Kushbago and Nak Hard Skin batang while the minimum values showed by genotype black batangi, Golden batangi and Shardi Tanchi. From above discussion it is concluded that these parameters play an important role in the identification of these genotypes belonging to the genus Pyrus.
