Mean frequencies of univalents in MI of meiosis in four F₁ hybrids of winter triticale (XTriticosecale Wittmack)

Combination	Number of PMCs scored	Percent of PMCs with full pairing	Univalents per PMC
			Wheat	Rye		Total
				Low arm ratio	High arm ratio
Presto × NE422T	100	46.0	0.42	0.86	0.36	1.64
NE422T × Stan 1	150	13.3	1.04	1.04	0.93	3.01
Mungis × Stan 1	100	36.0	0.64	0.86	0.34	1.88
Mungis × Krakowiak	150	45.3	0.28	0.82	0.43	1.53

“Low arm ratio” rye chromosomes are 1R, 2R, 3R and 7R; “high arm ratio” chromosomes are 4R, 5R and 6R
