چکیده
|
Genetic maps for two pear cultivars 'red bartlett' (pyrus communis l.) and 'nanguo pear' (pyrus ussuriensis maxim.) were constructed using srap molecular markers. the mapping population consists of 74 f1 individuals derived from the cross of a cultivar 'red bartlett' with good fruit quality as the female parent and a cultivar 'nanguopear' with good cold tolerance as the male parent. linkage maps for both parents were built with joinmap3.0. 103 markers have been mapped to 20 linkage groups covering 602.2cm with an average distance between markers of 4.89cm on maternal map,while 105 markers have been mapped to 20 linkage groups covering 650cm with an average distance between markers of 5.20cm on the paternal map. the map could lay a foundation for high density molecular genetic map construction for pear,and provide technique support for cold hardiness qtl detection and mas (marker assisted selection) in the future.
