Inheritance of quantitative characters in rice. II. Inheritance of panicle length



Inheritance of quantitative characters in rice. II. Inheritance of panicle length



Can J Genet Cytol 7(3): 406-417



Two cultivated rice varieties, Sabini (P1) and Pakistan-7 (P2) were crossed to determine the number of effective factor pairs controlling panicle length. The genetic design of the experiment included P1, F1, F2, and P2 populations. The field design of the experiment was a randomized complete block. It was found by applying the partitioning method of genetic analysis that the 2 parents were differentiated by 2 effective factor pairs. The data indicated the existence of partial phenotypic dominance for longer length of panicle (P1) over shorter one (P2). The genotypes of P1 and P2 were symbolized as AAbb and aaBB respectively. In studying factor interactions it was found that the factor A exhibited a higher degree of partial dominance over its allele a in all the genotypes. However, the dominance relations between B and its allele b were not consistent for the different genotypes. In substitution of a for A, the different genotypes did not have the same effect upon panicle lengths as did the substitution of b for B in the corresponding genotypes. It follows that these 2 factor pairs are not duplicates. The conclusion drawn from the interaction data could be that the degree of dominance with regard to both A and a; and B and b was dependent upon the genetic milieu.
