“…The magnitude and direction of combining ability effects are known to be useful in selecting parent plants in crop improvement programs (Mather and Jinks, 1971). In our study, crosses displaying high specific combining ability effects for grain filling duration, seed weight and yield were derived from parents with various types of general combining ability effects (high x high, high x low, low x low and medium x low).…”

“…The acquired data for all studied traits and for each year were statistically processed by the analysis of variance and LSD test was performed. Graphic analysis was applied to the data for each year according to the methods of Jinks (1954), Hayman (1954) and Mather and Jinks (1971).…”

The mode of inheritance of yield, topping height, leaf number, days to flowering, leaf length and width was studied by means of graphic analysis in a half diallel cross test of four burley tobacco varieties (Saturn, TN 86, Bs 92 and Bols 100) in 1998 and 1999. The trial was set up according to the RCBD at four replications in the experimental field of Tobacco Institute Zagreb in Pitomača. Overdominance in inheritance of all studied traits, except leaf length and width in 1998, was found by the graphic method. No interallelic interaction and epistasis were present as seen from testing regression coefficients for all investigated traits and years. The distribution of parental genotypes on a sca�er diagram along the expected regression line points to the genetic divergence of the parents. Parent Bs 92 appeared to have the most dominant alleles for yield and leaf length and parent Saturn for topping height, leaf number and leaf width.

“…For a single pair of loci all of the known classical non-allelic interactions can be directly equated with a unique combination of relative signs and magnitudes of d, h, i, j and I (Mather and Jinks, 1971). In the general case of many Joci with association at some pairs and dispersion at others only two types of non allelic interactions can be recognised; those in which [h] and [1] have the same sign (complementary) and those in which they have opposite signs (duplicates) (Jinks and Jones, 1958 To produce these observed relationships we would require that da = db = ha = h = lab = Jab Jba = 1ab at the level of a single pair of interacting loci.…”

INTRODtJCTION.. JINKs and JONES (1958) showed that the additive genetic, [d] and the additive x additive, [i] and additive x dominance, [j] interaction components of means estimated from the means of two pure-breeding lines (P1 and P2) and of their F1, F2, B1 and B2 families are functions of the degree of association (r) of alleles of like effect in the parents. Their real magnitudes and signs are therefore revealed only when the alleles of like effect are completely associated (r= 1) in the parents. In order to obtain a true picture of the gene action and interaction in Nicotiana rustica we have therefore investigated two crosses between pure breeding lines in which there is a high degree of association for the genes controlling most of the characters of interest. MATEPIALThe experiment consists of the P1, P2, F1, F2, B1 and B2 families of the cross between varieties 2 and 12 and between two of the D inbred lines, D10 and D17. Varieties 2 and 12 are two of the most extreme in the Birmingham collection. They display a high level of non-allelic interaction and produce the most heterotic F1 (Jinks, 1954). D10 and D17 are the extreme selections for final height from a random sample of 60D inbreds derived by single seed descent from the F2 of the V2 x V12 cross (see Jinks et a!., 1977). The coefficients of gene association/dispersion in these two pairs of parents estimated as described by Jayasekara and Jinks (1976) as the ratio of the difference between the parental means and the difference between the extremes of the random sample of D inbred lines for each character are as follows;Character "r" for V2 x V12 "r" for D10 X D7 Height-i, H1
