Table 1 Segregation analysis of the F₂ families derived from crossing NIL7 with HJX74

From: Identification of S23 causing both interspecific hybrid male sterility and environment-conditioned male sterility in rice

Chromosome	Molecular marker	No. of F₂ plants			χ²(1:2:1)	P value
Chromosome	Molecular marker	H/H	H/G	G/G	χ²(1:2:1)	P value
7	RM47	85	113	13	50.20	5.51E-15***
	M429	86	118	7	67.39	3.24E-14***

Note: H/H, G/G and H/G represented the homozygous genotype for HJX74, O. gulmaepatula and the heterozygous genotype, respectively, at the corresponding molecular markers. P value was determined with a Student’s t-test analysis. *** represented significance at P = 0.001
