In 1981 we released SICOT 3 to the industry. This variety is distinguished by glabrous (ultra-smooth) leaves and stems, and frego bracts (these morphological characteristics and their effects on pests are described in another paper - "Host Plant resistance Studies at Narrabri Research Station by myself, Peter Reid and Gary Fitt). However, besides advantages of Heliothis resistance and fibre quality, these characteristics are associated with less desirable agronomic effects such.as increased vegetativeness and delayed maturity. They also appear to be associated with higher sensitivity to some members of the bug complex, further accentuating rankness of growth and delayed maturity if these pests are not controlled.
