A new introduction from the Italian MAS.PES peach breeding program: ‘MAISSA’, a stony hard flat peach
No full textMAS.PES is an apricot and peach breeding program located in northern Italy aimed at the introduction of cultivars featuring enhanced fruit quality and disease resistance (http://www.maspes.org). Among the most promising commercial outcomes, ‘Maissa’, early selected as ‘BO06013020’, is to be mentioned. It is a flat, yellow peach from a [Sweet Cap x BO 96028059 (Spring Red x Big Top)] cross, ripening in late August/first week of September in northern Italy (southern Po Valley, 44°50’ latitude), around 50 days after ‘Big Top’ nectarine, a commercial cultivar of reference for the Italian peach industry. The tree growth habit is regular, of medium-high vigour, chilling is medium, yield is high; fruit shape is flat, rather regular, with over 70% blush, over 220g in weight; flesh texture is stony hard (Hd trait), while parents and grandparents were all classified as belonging to the slow softening texture type (a possible mutation at the F locus); it is of the ‘low acid’ type (D trait), with soluble solids over 17 °Brix when harvested at full maturity; it has a delicious flavour, rather unusual for a stony hard peach. Harvest could be adjusted according to commercial purposes, since flesh never melts, thus can be started when the fruit reaches 13 °Brix. ‘Maissa’ needs a careful field management in order to avoid brown rot damages on fruit
New introductions from MAS.PES, an Italian fruit tree breeding program: ‘Dulciva’ nectarine and ‘Pulchra’ peach.
No full textMAS.PES is an apricot and peach breeding program located in northern Italy aimed at the introduction of cultivars featuring enhanced fruit quality and disease resistance for the most important fruit growing areas. Among the most recent releases 'Dulciva' and 'Pulchra' are to be mentioned. 'Dulciva' is a nectarine from a 'Big Top' × 'Ambra' cross, ripening in late August (or first week of September as it is said after), around 40/45 days after 'Big Top'; the tree growth habit is regular and of medium vigour, chilling is medium; fruit shape is round, slightly triangular, with over 70% blush, weighting over 220 g; flesh is melting, slow softening; flavour is very good, of the low acid type with soluble solids around 14°Brix. 'Pulchra' is a very early peach issued from a 'Vista Rich' × 'May Crest' cross, ripening one week before the pollen parent; the trees growth habit is regular and of medium vigour, chilling is medium, fruit shape is perfectly round, but prone to elongated tip in warm environments, with over 90% brilliant blush, weighting around 110 g, flesh is melting, the flavour is balanced and very aromatic. Both are highly productive, with good fruit 'keeping ability' during ripening. 'Dulciva' is meant for widening the harvest window of 'Big Top' nectarine in the very late season for the northern peach growing regions in Italy (between 44N and 46N of latitude), while 'Pulchra' is better suited for environments with mild Springs in order to enhance fruit size
Breeding apricot in northern Italy
No full textAn apricot breeding programme was started at the University of Bologna (northern Italy) at the beginning of the 1980's and it's now co-led by the University of Milan. The basic goal of the project is to provide the southern Po Valley region with adapted cultivars to be grown in an environment featuring fluctuating temperatures at the end of the winter and the beginning of springtime, often ending in poor yield. Other goals are to obtain apricots of superior eating flavour and overall fruit quality, including appearance and firmness and/or slow ripening. Parents are chosen among germplasm collected from local cultivars (when featuring outstanding fruit flavour or tree hardiness) or from foreign sources, taking advantage of good cooperation with breeding programmes worldwide, aimed at exchanging either pollen or grafting material. One special goal is the resistance to Plum Pox Virus (PPV), as well as to the most common diseases (e.g. brown rot), or to fruit cracking. The project for PPV resistance is run in cooperation with the Italian Universities of Bari and Udine and has brought so far very promising results in terms of several advanced selections and one recently introduced cultivar ('Bora'), all field resistant to the two main PPV strains, D and M. The early ripening 'Ninfa' was the first introduction (1993) and an estimated half a million trees were sold in Italy since then, without mentioning other countries like Greece, Spain and Turkey. Among the more noteworthy recent introductions, in addition to the PPV resistant 'Bora' (large and firm fruit, with nice appearance), 'Petra', 'Pieve' and 'Pieve tardiva' are also to be mentioned because of their outstanding eating quality
