Genetic variation of fine individual plant's fruit characteristics of wild Amygdalus pcdunculata Pall in Inner Mongolia
In order to study the genetic variation and genetic diversity of important traits of wild Amygdalus pcdunculata Pall in Inner Mongolia,the correlation of yield and kernel rate with variation extent,variation form and characteristics of fine individual plants' fruit characteristics of wild A.pcdunculata Pall in Inner Mongolia were researched.The research showed that the quantitative characteristics of single fruit mass,length,width,length-width ratio and diameter in A.pcdunculata Pall had big variations.Single fruit mass had the biggest variations,and coefficient of variation was up to 0.27.So the single fruit mass had the biggest selection potential.Based on single fruit mass variation,the fruits could be divided into 7 groups,i.e.very small fruit,small fruit,smaller fruit,middle fruit,bigger fruit,big fruit,and very big fruit.Based on fruit length variation,they could be divided into 7 groups,i.e.minimal short fp() short fruit,shorter fruit,middle fruit,longer fruit,long fruit,and maximum long fruit.Based on fruit width variation,u could be divided into 6 groups,i.e.extremely narrow fruit,narrow fruit,narrower fruit,middle fruit,wider fruit,and wide fruit.Based on length-width ratio variation,they could be divided into 4 groups,i.e.wider round fruit,middle fruit,longer round fruit,and long round fruit.Based on fruit diameter variation,they could be divided into 5 groups,shorter diameter,middle diameter,longer diameter,long diameter,and extremely long diameter.Fruit characteristics in 4.pcdunculata Pall had no significant correlation with yield,fruit mass,width,diameter had very significant negative correlation with kernel rate,and fruit length-width ratio had very significant positive correlation with kernel rate.The conclusion can offer a theoretical basis and practice instruction for resources evaluation and breeding of new varieties of wild A.pcdunculata Pall.
