The Study Of Hereditary Variation Inclination On Filial Generation's Main Properties Of Big Fruit Sea-Buckthorn

The test adopts chuyi×mengyou1,chuyi×mengyou2,chuyi×mengyou3,chuyi×mengyou4,HS-21×mengyou1,HS-22×alieyi,suiyi×mengyou7,HS-20×alieyi eight hybrid composements of berry research institute of Suiling of Heilongjiang Province,240 departments of the filial generation,make these the material。The test make eleven properties do heredity analyse,The eleven properties are Soluble candy,organic sour,yellow pigmen,vitamin C,seed oil,and the heavy of fruit,the density of fruits,the length of carpopodium,the dentity of thorns,the high,flower。The result indicate to: 1 The analysis results of variance show:there is a remarkable difference in the the content of Soluble candy,The content of organic sour,The content of vitamin C the content of seed oil,the heavy of fruit,the density of fruits,the length of carpopodium,the dentity of thorns,the high the nine properties among each hybrid composement,the remarkable difference does not exist on the content of yellow pigment。2 The content of organic sour,the content of yellow pigmen, the content of vitamin C and the high the four properties belong to the quantity properties heredity,take on hereditary variation inclination of high parent。the content of Soluble candy,the content of seed oil,the heavy of fruit,the density of fruits,the length of carpopodium the five properties belong to quantity properties heredity too,take on hereditary variation inclination of low parent。The dentity of thorns take on hereditary variation inclination of similar parent。3 The content of Soluble candy, the content of seed oil,the content of vitamin C,the length of carpopodium,the dentity of thorns the five quantity properties their estimating value of narrow sense hereditary capacity are relatively high,it indicates influence coming from environment is small。The content of organic sour,the content of yellow pigmen,the heavy of fruit,the density of fruits and the high the five properties their estimating value of narrow sense hereditary capacity are relatively lower, it indicates influence coming from environment is big。4 Looking from coefficient of variation,coefficient of variation of the content of seed oil,the density of fruit and the content of vitamin C are relatively great,Hereditary stability of the properties is relatively small。the content of Soluble candy,the content of yellow pigmen,the length of carpopodium and the high the four properties their coefficient of variation are relatively little。Hereditary stability of the properties is relatively big。5 Looking from the eight hybrid composements:HS-20×Alieyi and HS-22×Alieyi their male parents are same,but female parents are not same, as to heredity of the seed oil,the density of the fruit and the density of the thorns, HS-20 makes female parent be superior to HS-22;as to heredity of the heavy of fruit and the length of carpopodium, HS-22 makes female parent be superior to HS-20。Chuyi×Mengyou1 and HS-21×Mengyou1 their male parents are same,but female are not same parents, as to heredity of the Soluble candy,the length of carpopodium and the density of the fruit, Chuyi makes female parent be superior to HS-21. Chuyi×Mengyou1,Chuyi×Mengyou2,Chuyi×Mengyou3 and Chuyi×Mengyou4 their female parents are same,but male parents are not same, as to heredity of the density of the thorns, Mengyou4 makes male parent be superior to Mengyou1,Mengyou2,Mengyou3;as to heredity of the vitamin C, Mengyou1 makes male parent be superior to Mengyou2,Mengyou3,Mengyou4。6 Flower heredity is the quality properties heredity。This experimental analysis results show:Eight hybrid composements accord with law of independent assortment,accord with 1:1 proportion。...
