Path diagram 2 showing 6 predictor variables and a residual effecting on criterion (var 7, nrds, plant related variate, num- ber of fully developed seeds per seed capsule), R2 = The path diagram explains of the variance of the criterion. The significance of paths was determined by random permutational test, 10000 iterations each, Bonferroni Correction. Path Analysis II (Fig. 3): The second path analysis, using the same variables as in the first analysis, was calculated to determine the influence of variables 3-6, 8 and 9 on variable 7, nrds, number of fully developed seeds per cap- sule, which is the most important plant related factor. Since variable 7 may be an indicator of fitness for the plant, it was subjected to a multivariate path analysis. There are 4 direct paths from the predictors to the crite- rion. The first direct path proceeds from var 3, nreh, to the criterion and is negative and very highly significant: the more escape holes, the less fully developed seeds per capsule. The second direct path from var 4, nrla, to the criterion is also negative and very highly significant: the more larvae, the fewer well developed seeds. The third di- rect path, from var 8, nrus, to the criterion is negative and very highly significant: the more undeveloped seeds, the fewer developed seeds per capsule. The fourth direct path, from var 9, nrss, to the criterion is also negative and very highly significant: the more spoiled seeds, the fewer well developed seeds. There are several indirect effects between the predictors and the criterion. The indirect effect proceeds from var 3 and var 8 to the criterion and is very high
