Coleoptile length variation of near-isogenic Rht lines of modern CIMMYT bread and durum wheats

A set of 10 bread wheat (Triticum aestivum L.) and six durum wheat (T. turgidum L.) genotypes near-isogenic for either the Rht1 or Rht2 dwarfing genes were analyzed for plant height, kernel weight, coleoptile length and grain yield. Coleoptile length was measured at three different temperatures and plant height, kernel weight and grain yield determined in six different environments. Durum wheat, regardless of stature, produced longer coleoptiles...
