Allelic Variations of the Waxy Gene and Their Associations with Indica-Japonica Differentiation and Amylose Content in Yunnan Local Rice Germplasm.

ABSTRACT:

Objectives

To provide insights for breeding high-quality rice varieties, we analyzed local rice (Oryza sativa L.) germplasm from Yunnan Province, China, focusing on the relationships among Waxy gene alleles, indica-japonica differentiation, and amylose content (AC).

Methods

We examined 201 local rice accessions. Two functional molecular markers for the Waxy gene were used to detect four alleles (Wx^a, Wx^b, Wxⁱⁿ, Wx^mw). Additionally, 33 InDel markers were employed to classify indica-japonica attributes, and AC was measured according to GB/T 15683-2008.

Results

We detected 175 accessions with Wx^a, 20 with Wx^b, 4 with Wxⁱⁿ, and 2 with Wx<
