a,b,A,BMeans of different genotypes at the same locus with the different uppercase letters were extremely significant (P < 0.01), and the different lowercase letters was significant (P < 0.05); The difference between the same letters was not significant (P > 0.05).
Means without superscript was not significant (P > 0.05).
