Detection and characterization of quantitative trait loci for coleoptile elongation under anaerobic conditions in rice

Figures & data

Table 1. Effects of CRATs for coleoptile elongation for Koshihikari alleles in the IR 64 genetic background.

Chromosome	Nearest markers of putative CRATs			Marker position (Mbp)	CRAT-dependent change (%)
3	P1676_3	-	P0484	10.6–16.3	+68
9	P0142	-	P0837	0.2–23.8	−68
10	P1445	-	K10sf100	13.7–19.4	−73

CRAT-dependent changes are expressed as the percentage change of the value determined in IR 64.
