Study On Biological Characteristics,the Buds Of Salt-Tolerant And The Preliminary Relationship Of Wild Soybean

Based on biological characteristics of the investigation of wild soybean,the salt-tolerance of germination and the relationship of the preliminary study, to find comprehensive agronomic traits,and strong salt-tolerance of germination,relationship far from the wild soybean materials,As a male parents to hybrid with soybean cultivation,the fine characteristics of wild soybean import into soybean cultivation,to broaden the genetic basis of soybean cultivation have a greater significance.The results show that:1.The 4 samples from Beijing are semi-wild soybeans,the 48 samples from Jilin province are typical wild soybean.By comparative analyzing of agronomic traits know that it is quite different on biological characteristics of wild soybean which come from different area;the protein content of wild soybean from Beijing is lower than Jilin,but oil is higher than Jilin;in yield,the wild soybeans from Beijing are superior to Jilin.2.Base on the biological characteristics of white-flowered wild soybean survey results show that:white-flowered wild soybean of Jilin and Beijing.Although flower color is same,but the other characters all have a great difference.The protein content of Beijing is less than Jilin,oil is on the contrary.3.Through wild soybean of Jilin biological characteristics of the survey results show that Besides the color of flower is different,there is no significant difference between the remaining characters of white and purple wild soybeans of Jilin.4.The relationship between main agronomic traits and per-plant yield shows that every main agronomic traits and per-plant yield showed a significant positive related;one-hundred weight and growth period,number of grains of pods per plant,number per plant and shows very positive significant related;number per plant and growth period,number of grains of pods per plant shows very positive significant related;number of branches of main stem and number of grains of pods per plant,number per plant shows significantly negatively related,number of branches of main stem,and 100-seed weight,per-plant yield shows very significantly negatively related;number of branches of main stem and growth period shows negatively related.5.After determing the salt-torlance of 52 samples in germination stage found the 0.6%concentration of NaCL is suitable to determine the salt-tolerance in stage The salt-tolerance of No.4 is the most strongest,the salt tolerance of No.36is also relatively strong,No.42,No.6,No.9,No.18,No.46,No.38,No.14,No.10,No.24,No.35,No.33,No.36,No.34,have strong salt-tolerance;although No.5and No.40 did not endure 0.8%NaCl concentration,but in 0.6%concentration showed relatively strong.6.Analysised the peroxidase isoenzyme electrophoresis of 48 samples shows that there are 2-7 isoenzyme bands when the relative transport relocity(Rf) is 0.4677 and 0.2015 there are two distinct bands.At Rf 0.2834 appeared a specific bands of No.24 sample.7.Culster analysis of Peroxidase isoenzyme enzyme spectrum showed that, clustering results is irrelevant to habitats and geographic distance.The genetic distance on the level of isozyme is irrelevant to external environment.
