Abstract: A new and distinct Pyrus communis L. pear tree variety named ‘PE3UNIBO’, is particularly characterized by the following features: medium vigorous and slightly compact trees with upright habitus; bearing habitus normally on spurs on 2-3 years old branches and sometimes on 1 year old shoot; good grafting compatibility with the main quince rootstocks; early medium ripening (about 1-2 days before ‘Bartlett’); high and constant yield; early bearing; good size of fruit (about 200 g), ranging from pyriform to pyriform-elongated shape; green skin until the full ripening stage with a slight russet; tender and juicy white flesh at the full ripening stage with a very good flavor that is slightly sour; long storage capacity in cold room is, until 5 month.

Abstract: The new and distinct Pyrus communis L. pear tree variety named ‘PE1UNIBO’ is particularly characterized by the following features: medium-high vigorous trees with upright growing habitus; bearing habitus normally on spurs on 2-3 years old branches; good grafting compatibility with the main quince rootstocks; early ripening (about 9 days before ‘Bartlett’); high and constant yield and early bearing; green fruit, also when ripe, with slight russet (20-30%); fruit medium size with regular pyriform shape; tender and juicy white-cream flesh at full ripening stage with a very good flavor and high sugar content; possibility of eating the pear at the harvesting time, when crunchy; long storage capacity in cold room, up to 5-6 months.

Abstract: A new and distinct Pyrus communis L. pear tree variety named ‘PE2UNIBO’ is particularly characterized by the following features: medium vigorous trees with semi-upright growing habitus; bearing habitus normally on spurs on 2-3 years old branches and on 1 year shoots; good grafting compatibility with the main quince rootstocks; early ripening (about 15 days before ‘Bartlett’); high and constant yield and early bearing; good size of the fruit (over 200 g) with regular pyriform shape; green skin at picking time and yellow-green at full ripening stage (after the cold storage), with an attractive red-orange over-color in the fruit surface previously exposed to sun; tender, juicy and white flash, with a very good flavor (good sugar-acid balance) at full ripening stage; long storage capacity in cold room, up to 5-6 months.

Abstract: A new and distinct Pyrus communis L. pear tree variety named ‘PE4UNIBO’ is particularly characterized by the following features: medium vigorous trees with semi-upright habit; bearing habitus mainly on 1 year old shoots and subsequently on 2-3 years old branches (like ‘Bartlett’); partial grafting incompatibility with quince rootstocks; medium late ripening (about 15 days after ‘Bartlett’); medium productivity; big size of the fruit (about 300 g) with pyriform-elongated shape (like ‘Abbé Fétel’); yellow-green skin with a nice red over-color on 70-80% of surface; tender and juicy white flesh, at full ripening stage and with a very good flavor and sweet taste; long storage capacity in cold room up to 6 months.
