“…All nuts including pecan are good protein sources, containing few saturated fats, cholesterol free and high in unsaturated fats (Silva et al, 1995). The unsaturated fats in pecan are protected against oxidation by the high concentration of y-tocophenol and polymeric flavones (Haddad et al, 2006 andAttia &Wafaa, 2007).…”

This evaluation included morphological, flowering, yield and fruit quality, physical characteristics as well as kernel oil fatty acids composition and the ability to vegetative propagation by grafting. The Effect of environmental conditions on dichogamy phenomenon was also studied. It can be clearly noticed that, there is a positive relation between shoot length & diameter, av. No. of leaves per shoot and internodes length, where Burkett variety was the superior in this concern, while, Pawnee variety exceeded the others in twig length and No. of shoots/twig. Desirable var. recorded the highest No. / of leaflets/leave and leaflet area. Western Schley had smaller tree size. There was an obvious varietals difference in pecan bud developmental stages (dormant, vegetative and starting buds for staminate or pistillate inflorescences). The highest No. of the abovementioned buds as well as total No. of such buds and No. of fruits/shoot was observed in Western Schley variety except for No. of vegetative buds. Fruit set (%) averaged between 66.04 & 66.04 in Wichita to reach 85.60 & 82.57 in Desirable. Number of days in which pollen shed coincides with stigma receptivity varied between the studied varieties, where there was more consistent period of overlap in Pawnee, Success & Western Schley varieties. The previously mentioned varieties can be classified as protandrous (type, 1), whereas, Burkett, Desirable & Wichita varieties as protogynous ( 2). Moreover, Wichita can be considered a good pollinator for most other studied varieties. Pollen shedding period in Wichita extended with the increase of relative humidity and lower temperature. Burkett followed by Success varieties started and ended to crack shuck and harvesting earlier than other varieties. Western Schley, Desirable & Burkett varieties had an excellent kernel ercentage, respectively, whereas, Pawnee variety was the poorest. Varieties with high nut weight had lower No. of nuts /kg. Desirable followed by Burkett produced the highest yield, while, Success was the lowest. In regard to kernel oil content (%), Desirable followed by Western Schley kernels were the richest. The main compositional characteristic of pecan kernel was the high concentration of oleic acid and very low content of Linolinec acid. It is also interesting to note that, successful grafts (%) varied between varieties from 33.33 % in Western Schley to reach 93.33 & 91.66 % in Desirable & Success, respectively. As a conclusion under the same conditions of the present study Burkett & Success may be recommended as early cropping varieties; Wichita as a good pollinator; Western Schley as a small size tree which can be helpful in increasing number of trees / Fed. which in turn increases yield/Fed. as well as may facilitate the trees cultural practices. The primary pecan varieties Desirable & Burkett performed superior to other varieties in terms of yield; Western Schley and Desirable as varieties that have higher percentages of kernel and oil content and Desirable & Success are characterized by their easy...

“…Sensory research has demonstrated that the flavor of pecans can indeed depend on the pecan genetics. Two studies (Magnuson et al, 2016;Silva et al, 1995) showed that different clones have different flavor profiles, but the authors also remarked that environmental conditions probably played a larger role than genetics. The studies did not include native pecans and used a trained sensory panel of 6 to 12 individuals.…”

A Sensory Analysis of Raw Native, ‘Kanza’, and ‘Pawnee’ Pecans

The purpose of this study is to evaluate the appearance, texture, color, and taste of two popular pecan (Carya illinoinensis) clones relative to native pecans in a blind sensory analysis. Subjects tasted the raw pecans acquired from the same farm and evaluated them using hedonic scores. Results suggest consumers prefer the two clones to natives, and most of this preference seems to be related to the pecan size. A crossmodal effect was detected whereby the subjects reported an improved flavor in whole native pecans compared with clones that were cut in half and were thus less visually appealing. Consequently, although a previous study showed that consumers prefer pecans in a hypothetical (nontasting) situation when they are labeled as a “native” as opposed to clones, when the pecans are actually eaten and there are no labels designating the pecan type, they prefer the clones.
