Agronomic and Fiber Properties of Smooth, Nectariless ‘Acala’ Cotton1

  1. Dick Davis2

Abstract

Abstract

Genes for semi-glabrous leaf and nectariless plant were transferred into ‘Acala 1517’ cotton (Gossypium hirsutum L.) from the insect-tolerant strain 1514, which carries the Sm1sl, ne1, and ne2 genes. The F2 progeny of this cross approached the midparent in agronomic and fiber properties. A semi-glabrous, nectariless selection from the above cross was hybridized with a selected experimental strain from Acala 1517. The unselected F2 progeny of the second cross appeared to be essentially equal to the Acala 1517 parent in disease resistance and agronomic and fiber properties.
