EVALUATION OF PRODUCTIVITY AND FRUIT QUALITY FOR SIX NEW PEACH AND NECTARINE ROOTSTOCKS
Fruit quality and productivity of 8-year-old peaches and nectarines, grafted onto Cadaman-Avimag, Viking, Atlas, G×N 15, GF 677, MRS 2/5 and Nemaguard rootstocks (with Nemaguard considered as the control), were evaluated during the 2008-2009 growing season.
The trees were planted in the Univiveros Experimental Nursery in Paine (Metropolitan Region, Chile). Total yield, fruit size distribution, number of fruit, and fruit weight were recorded.
Fruit quality parameters including total soluble solids, blush colour development, and flesh firm-ness were also measured.
On average, Cadaman yielded the highest weight and number of fruit, compared with the control, followed by G×N 15, Atlas and GF 677 to a lesser degree, while Viking was similar to the Nemaguard control, and MRS 2/5 yielded less than the control.
There were no great differences between the rootstocks and the control with respect to average fruit size and weight, although the most vigorous, Cadaman and G×N 15, were significantly higher (190.1 and 197.2 g, versus 179.5, respectively). For fruit quality parameters, Viking had the highest accumulation of total soluble solids with respect to Nemaguard (11 to 10.8°Brix) and MRS 2/5 had the highest percentage of blush colour compared with the control (78.3 versus 71.9%). For flesh firmness at harvest, GF 677 was the firmest (9.3 lb.) and MRS 2/5 was the softest (7.3 lb).
