Evaluation of Some Morphological and Flowering Traits in New Six Olive Genotypes Grown under Egypt Conditions

Abstract

The present investigation was conducted during two growing seasons (2016 and 2017) to evaluate six genotypes of olive trees. The experimental olive trees were propagated by leafy cutting under mist propagation system. The leafy cuttings were already taken from seedy propagated olive trees which have already been planted since 1994 at the farm of Horticulture Research Institute, Giza Governorate, Egypt and were produced from breeding program of Horticulture Research Institute. i.e., Genotype 25 derived from Aggizi cv. open, Genotype 61 derived from ♀ Hamed cv. x Picual cv. ♂, Genotype 97, 91 derived from Manzanillo cv. open, Genotype 66 derived from ♀ Toffahi cv. x Arbiquna cv. ♂ and Genotype 138 derived from ♀ Arbiquna cv. x Hamed cv. ♂. Therefore, the present study was carried out to evaluate some morphological and flowering of the six olive genotypes grown in olive collection farm located at Cairo-Alexandria desert Road (about 64- kilometer distance from Cairo). To determine the most promising genotypes for local conditions. Herein, the greatest values of morphological traits were significantly coupled with genotype (91) during both seasons of study. Moreover, genotype (97) ranked statistically second. Moreover, the start of flowering in six olive genotypes occurred during the period from March 13th to April 3rd in the first season and from April 1st to April 10th in the second season. Referring to blooming dates and blooming periods results obtained that dates of full bloom were earliest in the first season than that at the second season. Furthermore, olive genotype (138) was statistically the superior and resulted significantly the highest perfect flowers % during both seasons of study.
