Genetic Analysis of Leaf Rolling in Wheat

INTRODUCTION Leaf rolling may be associated with improved grain yield in some drought situations. Evidence of varietal differences for leaf rolling in wheat (Triticum aestivum L.) has been reported [1], but studies investigating the amount and nature of genotypic variation in leaf rolling of wheat are rare [2]. The aim of this work was to determine the genetic system governing leaf-rolling in wheat using two separate approaches: 1 – by analysing generation means in two bi-parental crosses; and 2 – by using a diallel-mating design.
