Diversity of starch physico-chemical properties and haplotypes of starch-synthesizing genes in Thai rice

The physico-chemical properties of starch in the rice grain which include the apparent amylose content (AAC), the gelatinization temperature (GT) and the gel consistency (GC) are important characters of interest to breeders. We studied starch physico-chemical properties and the genotype of starch-sy...

We studied starch physico-chemical properties and the genotype of starch-synthesizing genes in Thai rice varieties. One hundred and sixty accessions of Oryza sativa from Thailand were evaluated for AAC, GT and GC, and were assayed using PCR-SSCP at seven loci coding for starch-synthesizing genes. The AAC varied from 1.11% to 30.07%.

For the GT, significant differences were indicated only at the GBSSI locus. 2018-09-10T03:26:11Z 2018-09-10T03:26:11Z 2009-07-01 Journal 16851994 2-s2.0-77953754749 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=77953754749&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/59988
