Phenotypic correlation of pea grain yield or pea proportion in mixed stand with cereals (MS) with pea or cereal yield traits in MS or pea yield in pure stand (PS), for 144 pea inbred lines grown in two cropping years.

	Pea grain yield in MS		Pea proportion in MS
Trait	2018–19	2019–20	2018–19	2019–20
Pea proportion in MS	0.98**	0.96**	–	–
Associated cereal grain yield in MS	−0.31**	0.04 NS	−0.46**	−0.16*
Total (pea + cereal) grain yield in MS	0.60**	0.77**	0.46**	0.62**
Pea MS/PS grain yield ratio	0.64**	0.90**	0.64**	0.85**
Pea grain yield in PS	0.28**	0.30**	0.27**	0.35**

^{NS, *, **}, correlation not different from zero and different from zero at P < 0.05 and P < 0.01, respectively.
