Abstract:
Three hundred and sixty-five seedlings of Nanguo pear × Red Bartlett pear hybrids were used as test materials，the genetic tendency of Nanguo pear × Red Bartlett pear progenies was studied by investigating and analyzing leaf morphology,fruit morphology and internal quality of fruit,in order to provide reference for pear hybrid breeding work.The results showed that the genetic tendency of cold resistance and growth potential of reciprocal cross progenies of Nanguo pear × Red Bartlett pear was very strong.The leaf shape was mostly similar to the parent and was oval;leaf size was mostly between the medium and its parented;the shape of leaf base mainly presented the round leaf base of the parent;the shape of leaf tip and leaf margin were mainly consistent with the female parent.Fruit shape widely separated,but mostly round;fruit quality tended to degenerate towards small fruit;the background color of fruit was inherited from mother.The fruit flavor was mainly sour and sweet;flavor was recessive;fruit juice performance had a decreasing trend;the genetic transmissibility of soluble solid content was strong,mostly higher than the median value of parents.
