Evaluation of a new selected apricot strain under the conditions of Nubaria region. Egypt.

Includes references.

This Investigation was conducted in two dependent experiments at the Nubaria Horticultural Research Station, Behaira Governorate Egypt to evaluate a new apricot strain from 2003 to 2009. The first experiment was to study the behavior of this strain and the second was to compare it with the well adapted Canino apricot cultivar. The trees were budded on apricot seedling and planted in a calcareous soil. The evaluation of the new apricot strain was based on the beginning date of growth and yield as well as physical and chemical characteristics of fruit. The beginning date of harvest was earlier than Canino by 10- 15 days in the two seasons. It was found to be significant over Canino in carrying yield (number fruits per tree 749.5 and 1353.0), flesh percentage (93.43 and 94.10%) and SSC percent (14.27 and 12.43%). The fruit weight was greater for Canino cultivar than the new apricot strain (35.93 and 31.93 gm). Consequently yield in kilograms per tree (24.57 and 35.20kg). The fruit firmness was 7.3 and 9.0 (Ib/ Inch2). In both cultivars, the new strain and Canino, the majority of the fruits were born on one year old shoots, the lowest number of fruits on spur increased. In addition, productivity and fruit quality were better than the Canino one.
