This part describes the results obtained by using the parents, Kunmingxiaobaigu, on indigenous variety with cold2tolerance from Yunnan, and Tow2 ada, a cold2sensitive variety bred in Japan, as well as their F 2 progenies as tested materials, combining by using 159 RFLP and SSR markers and STATISTIC software. The total fertility percentage ( TFP) was used as indicator of cold tolerance. The coefficient of relationship between TFP and special fertility percentage( SFP) of single plant was 0. 8364. 43 markers were related to cold tolerance based on the TFP as its indicator, distributed in eleven regions on eight chromosomes while 34 ones related to SFP over nine regions on seven chromosomes. The seven chromosomes related to SFP belonged to the eight ones related to TFP. The nine regions related to SFP belonged to the eleven regions related to TFP. The above results showed that SFP can be used to represent TFP in evaluation of cold tolerance. The issue over SFP to represent TFP in other fields was discussed.
