- Two separate field trials, one with 22 multipurpose white-flowering cultivars and second with 8 cultivars of feed pea, were conducted to determine the degree of damage to seeds caused by the pea moth (Cydia nigricana) and pea weevil (Bruchus pisorum) and to study important agronomic traits of pea cultivars. Damage to pea seeds by the pea moth and pea weevil was common in the central region. The pea cultivars tested differed in their susceptibility to these two pests, as reflected by the value of percentage seed damage. The percentage of seed damage caused by pea weevil in this study was tenfold higher than that by pea moth. Highly significant effect of years of cultivation on all examined traits was shown. Seeds damage by both insects was most strongly affected by the precipitation and to lesser extent by mean daily temperature during pea growing seasons. For the set of white-flowering cultivars, the correlation between the amount of damaged seed and the amount of precipitation was r = - 0.47 and r= - 0.76 for pea moth and pea weevil respectively, while in feed pea cultivars only for seeds damaged by pea weevil a significant correlation (r= -0.84) was found. The second abiotic factor, mean daily temperature had a positive effect on the amount of damaged seeds, particularly caused by pea weevil in feed pea (r= 0.84). The cluster analysis identified cultivars with the lowest percentage of damaged seeds and high yield performance.
