Abstract

The present study was carried out on 32 female Jojoba" simmondsia chinensis-Link" shrubs were about 12 years old during 2007 & 2008 experimental seasons. The shrubs have been grown at the Experimental Orchard of Ali Moubark, south El-Tahrir, El-Behira Governorate, Egypt. The shrubs growing in sandy soil in two lines a & b at distance of 5 X 5 meter apart and irrigated with drip irrigation system. The present study was aimed to select the best shrubs on yield and a considerable amount of seeds contained higher oil, as well as propagated the selected shrubs using soft stem cutting to study their rooting ability. The morphological characteristics of jojoba shrubs (vegetative growth characters, flowering, and fruiting), yield as well as seed physical and chemical proprieties were stimated in this study. The results showed that the growth vigor of shrubs varied to be strong, moderate and weak while most of shrubs were a drooping in habit growth. Shrub No.8 b had the highest shrubs height, seed length, width and weight, while shrub No.22a had the highest value of circumference and shrub No. 6a had the highest number of leaves/ meter, leaf area and leaf L/W ratio, number of flowers and fruits per meters in both seasons. Shrubs No.15a, 8b had the highest leaf area and leaf L/W ratio, along with their, yield was differed from first and second seasons. Shrub No.6a was a superior in both seasons with seeds yield of 3.250 kg in the first season and 3.133 kg in the second season. The highest number of ridges was observed in shrub No.2b, number of grooves were varied from 2 to 3 grooves and the highest seed oil content was in shrub No.13b with the percentage of 60.70% and 61.09% in the first and second seasons. Concerning vegetative propagation of the best jojoba shrubs in yield and seed oil content (No. 6a, 2b, 8b, 13b, 14b), data showed that shrub No. 6a had the highest percentage of rooting cutting, length of root and fresh weight of roots, while shrub No. 13b had the highest number of roots per rooting cutting and shrub No. 14b had the highest dry weight of roots. The natural degree of variability appeared enormous, that gives a plant scientist a huge range of possible gene combinations for future selection and improvement of jojoba as a new-industrial and commercial crop.
