Indirect selection for resistance to fusiform rust in Loblolly pine

Abstract

Indirect selection for resistance is superior to direct selection under certain conditions. The phenotypic correlation was studied between resistance to fusiform rust (Cronartium fusiforme) in loblolly pines (Pinus taeda L.), chosen by a newly-developed stability index, and the amount of resin acids, growth-inhibiting substances, and fatty acids extracted from pine tissue. No association was found between rust resistance and the amount of total or individual resin acids in clones or families. The amount of growth-inhibiting substances present in branches from full-sib families was greater in rust-resistant compared to rust-susceptible families. A strong association was found between resistance and the amount of long-chain fatty acids in four clones. A weak association was found between resistance and the amount of the fatty acid 18:2 in five other clones.
