| Walnut is an important economic tree species in southern Xinjiang.The walnut seed is rich in nutrients and has unique advantages in medicine and health care.It is called “super food” by experts.In this study,the excellent walnut Wen 185,Xinxin 2 varieties and their live offspring populations were selected from Xinjiang,and the fatty acid content,protein,amino acid,mineral elements,soluble sugar,and singles of the parents and the offspring were compared.Intrinsic quality differences,the correlation of quality indicators can be analyzed,and provide a theoretical basis for future breeding..The main research results are as follows:1.The fat content of Wen 185 nut is 68.11g/100 g,the average value of the offspring is 64.62 g/100 g,The average values of monounsaturated fatty acids,polyunsaturated fatty acids and saturated fatty acids of the parent nuts are 19.00%,69.70% and 11.30%,respectively.In fact,the offspring are 15.54%,72.39%,and 12.07%,respectively.The fat content of Xinxin 2 nut is 66.55 g/100 g.In fact,the average value of the offspring is 66.48 g/100 g.The parent nut is not fatty,polyunsaturated,saturated.The average fatty acid content was 17.03%,71.01%,and 11.96%,respectively.In fact,the offspring were 17.42%,70.95%,and 11.63%,respectively.This study shows that high oil(oil content,unsaturated fatty acid)can be seen as temperature 185.Among the live descendants,North 6-16,North 4-16,North 1-14,North 1-9;Xin xin 2 in the offspring,Medium 1-12,Medium 2-12,Medium 4-12,Medium 6-8,Medium 6-9,Medium 6-10,can be considered as a better single plant.2.The protein content of Wen 185 nut is 17.77 g/100 g,the average value of the offspring is 18.86 g/100 g,the amino acid content of the parent nut is 15.02 g/100 g,the average value of the offspring is 16.32 g/100g;the total content of essential amino acids of the parent nut is 3.85 g / 100 g,in fact,the average value of the offspring is 4.20 g/100 g,the essential amino acid content of the parent nut accounted for 25.60% of the total amino acid,in fact,25.73% of the offspring.The protein content of Xin xin 2 nut is 18.23 g/100 g,in fact,the average value of the offspring is 18.10 g/100 g,the amino acid content of the parent nut is 15.40 g/100 g,the average value of the offspring is 15.95 g/100g;the essential amino acid content of the parent nut is 3.86.g/100 g,in fact,the average value of the offspring is 4.13 g / 100g;the essential amino acids of the parent nut account for 25.09% of the total amino acid content,in fact 25.84% of the offspring.This study shows that high protein and high amino acid can be seen as indicators,Wen 185 live descendants,North 1-9,North 3-11,North 4-10,North 6-11,North 6-16;Xin xin 2Among the live generations,Medium 2-9,Medium 4-8,Medium 5-9,Medium 5-12,Medium 6-8,and Medium 6-12 can be considered as superior plants.3.The total contents of 12 mineral elements in Wen 185 and Xin xin 2 nuts were 1115.29mg/100 g and 933.59mg/100 g,respectively.In fact,the progeny were 1227.55mg/100 g,1029.76mg/100 g,and the mineral elements of walnut nut and The content is rich,and the content of P element is the highest,indicating that P is the main mineral element in walnut kernel.The mineral elements in Wen 185 and Xinxin No.2 nut have the highest content of P,which are 563.24 mg/100 g and 386.96mg/100 g respectively.In fact,the progeny are 608.54mg/100 g and 439.28mg/100 g respectively;this study shows that the high Nutrition can be seen as indicators,Wen 185 generation,North 1-10,North 3-13,North 4-16,North 6-9,North 6-11;In the new generation of Xin Xin 2,Medium 1-11,Medium 2-12,Medium 3-11,Medium 4-12,Medium 5-9,Medium 6-11 can be considered It is a better single plant and can be used as a suitable type for the development of functional foods for walnut fruits.4.The soluble sugar content of Wen 185 nut is 5.20g/100 g,the average value of the offspring is 5.00g/100g;the ash content of the parent nut is 2.02g/100 g,the average value of the offspring is 2.05g/100g;the tannin content of the parent nut is 0.52g/100 g,in fact,the average value of offspring is 0.50g/100 g.The soluble sugar content of Xinxin No.2 nut is 4.79g/100 g,the average value of the offspring is 4.99g/100g;the ash content of the parent nut is 1.98g/100 g,the average value of the offspring is 2.02g/100g;the tannin content of the parent nut is 0.52g/100 g,in fact,the average value of offspring is 0.58g/100 g.This study shows that high sugar and high nutrition can be used as indicators.Among the warm 185 generations,North 1-9,North 2-9,North 4-10,North 6-10,North 6-13,North 6-16;In the new generation of Xin Xin 2,Medium 1-10,Medium 1-12,Medium 2-12,Medium 4-8,Medium 6-9,Medium 6-10 can be considered It is a better single plant.5.The comprehensive index is expressed as follows: the main component combines the intrinsic quality of Wen 185 walnut and the seed of the offspring,and the representativeness reaches 88.43%.According to the utilization trend of the walnut market and the selection target,the main component combination is used to represent the different utilization directions of Wen 185 walnut.Evaluation index.The first main component is represented by total amino acid and essential amino acid.The first type of total amino acid and essential amino acid rich walnut powder represent the offspring: North 1-9,North 3-11,North 3-13,North 4-11;The second main component is represented by saturated fatty acid and soluble sugar,and the second type of saturated fatty acid and soluble sugar-rich walnut milk represent the offspring: North 1-11,North 4-10,North 4-16,North 7-15;The third main component is represented by fat,and the third type of oil comprehensive index mainly refers to the production of walnut oil.Representing descendants: North 1-14,North 4-16,North 6-10,North 6-16,etc.the main component combination is used to represent the evaluation index of the different utilization directions of the Xin Xin 2 walnut.The first main component is represented by total amino acid,essential amino acid and unsaturated fatty acid.The first type of total amino acid,essential amino acid and walnut powder rich in unsaturated fatty acid represent the offspring: Medium 3-10,Medium 4-8,Medium 5-9,Medium 6-12;the 2nd main component is represented by saturated fatty acid and total amino acid,the second type of saturated fatty acid and walnut milk rich in total amino acid,representing the offspring: Medium 3-11,Medium 4-12,Medium 5-12,Medium 6-12;the third main component is represented by fat and soluble total sugar,and the third type of oil comprehensive index mainly refers to walnut oil production and soluble total sugar content rich walnut milk,representing offspring: Medium1-10,Medium 2-12,Medium 3-10,Medium 6-10,etc.6.Studies have shown that the intrinsic quality analysis of the two generations of Xinjiang Wen 185 and Xin Xin 2 walnut varieties,in summary,can be seen that the parental comparison and the high nutritional value of the parent are the indicators for screening good strains,among which high oil(oily)Rate,unsaturated fatty acid,high protein,high amino acid,high mineral element,high sugar,high tannin,etc.)can be seen as indicators,Wen 185 live offspring,North 1-9,North 1-14,North 3-11,North 3-13,North 4-10,North 4-16,North 6-10,North 6-16;Xin Xin 2 the middle generation,Medium 1-10,Medium 2-12,Medium3-10,Medium 3-11,Medium4-8,Medium5-12,Medium 6-10,Medium 6-12,etc.can be considered as superior plants.Studies have shown that Wen 185,Xin Xin 2 walnut varieties and the mineral elements in the actual generation are relatively rich,which provides a good germplasm resource for the selective breeding of varieties,especially high-content nutrient varieties.The progeny of the Xinjiang Aksu walnut variety can be used as a potential material for natural selection of walnut varieties,which is conducive to obtaining higher economic value types. |
