Meliaceae the toon genus perennial deciduous tree toon (Toona sinensis (A.Juss) Roem), in our country it is a very important woody vegetables, and main edible young leaves and buds, its delicious aroma high nutritional value. But this many places is still picking traditional farmhouse varieties, these farmers varieties of good and bad. 130 plants derived from Badong ZHUXI, Hubei Wuhan Lion Rock, 15 kinds of source material in the test. Excellent monoclonal elect the 130 per plant. A main content of the test is the toon conducted the sensory identification, based on vegetables sensory identified requirements, determine the toon the 7 sensory quality indicators: color, aroma, tenderness, sweetness, astringent, chewy, shiny. Then, based on the principle of organoleptic evaluation score, using a 5-point scale, each indicator to determine the five grades by expert scoring of each monoclonal sensory evaluation, assign a score to each sensory indicators. Through AHP (Analytic Hierarchy Process) analysis to determine the weight of each index in the share of Priority Selection. The weight of each indicator were: color 0.353 0.284 aroma, tenderness 0.166 sweetness 0.084, chewy 0.052, astringent degrees 0.037 shiny 0.025 Total 1.000. 130 per plant the biological traits phenology period of observation records. The biological traits recorded the characteristics of the trunk and stems, including the trunk color, texture, stem color, texture, lenticels situation. Record the morphological characteristics of mature leaves, including: the length, color, expansion angle of fronds, the number, color, size, etc. of the lobules. Record the morphological characteristics of the young leaves the leaves can eat period. The phenophase the bud scales loosening period infancy, began to leaf expansion, leaf unfolding prime the spring shoots began growing season, spring shoots end of the growing season, summer shoot began growing season and the summer shoot end of the growing season, the leaves began to change color period , leaf discoloration completely period leaves start shedding period, deciduous the peak, deciduous final. Sensory score ratings matrix and weight matrix multiplied by the total score of each monoclonal. The individual total scores were compared under isometric wholly slice method is excellent as higher than the average 20.1%, higher than the average 10.1% to 20% as good, and 0 to 10% Average to below average 0 ~ 10% as poor, below the average of 10.1% or less poor initial screening out of 29 fine individual, respectively: T4-32, T3-5, and T3-18, T4-13 T3-22, T1-1, T1-29, T3-13, T2-15, T2-44, T4-31, T1-3, T2-22, T3-16, T2-21, T4-19, T1- 38, T1-26, T1-34, T1-35, T4-11, T3-9, T1-16, T1-33, T1-36, T3-12, T2-25, T1-15, T2-34. The determination of these 29 fine individual nutritional quality, including: water, soluble sugar, protein, amino acids, crude fat, crude fiber, vitamin C, tannins. Through sensory evaluation, the biological traits of determination, the determination of the nutritional quality of the results obtained, on this fine individual 29 made a comprehensive evaluation.
