Line × Tester Mating Design Analysis for Grain Yield and Yield Related Traits in Bread Wheat (Triticum aestivum L.)

Table 1

ANOVA for line × tester analysis.

Source of variation	Degree of freedom (df)	Mean square
Replication (𝑟)	(𝑟−1)
Genotypes (𝑔)	(𝑔−1)	MS2
Parents (𝑝)	(𝑝−1)
Parents versus crosses	1
Crosses (𝑐)	(𝑐−1)
Lines (𝑙)	(𝑙−1)	𝑀𝑙
Testers (𝑡)	(𝑡−1)	𝑀𝑡
Lines × testers	(𝑙−1)(𝑡−1)	𝑀𝑙×𝑡
Error	(𝑟−1)(𝑡−1)	MS1

Where MS₂, 𝑀_𝑙, 𝑀_𝑡, 𝑀_𝑙×𝑡, and MS₁ were genotypic mean square, line mean square, tester mean square, line × tester mean square, and error mean square, respectively.
