Abstract
Description
Wheat is a subtropical crop with a limited genetic resources in indonesia since it belong to tropical country. Convergent breeding is an effort to expand genetic diversity in wheat and to get the plant genotipes that have spesific characters. The aim of this reserch was to determine genetic diversity of wheat segregants resulted from convergent breeding using Simple Sequence Repeats (SSRs). Fifty seven wheat genotipes were tested using 39 SSR markers to determine their diversity. The results showed grouping by upgma of similarity matrix with genetic similarity coefficient ranged from 0.30 to 0.95. The similarity coefficient at 0.3 separated the 57 genotipes into two groups: the first group consisted of segregants, Oasis and Guri1 and Guri2 and the second group consisted of Dewata, Alibey, Rabe/M088, Selayar, HP 1744 and Tepoca/Rabe. Alleles which are formed from the entire genotipes using 39 primers were 137 alleles with a range of base pairs formed between 85.6-553 bp. PIC value and the average number of alleles were 0.35 and 3.51, respectively. The genetic variability being increased in wheat germplasm population and obtained 22 candidates of genotipe recombination having a high value of genetic distance (≥0.75) with a chance of many recombination.
