Introgression of chromosome 1P from Agropyron cristatum reduces leaf size and plant height to improve the plant architecture of common wheat.
Theor Appl Genet. 2022 Jun; 135(6):1951-1963.TA

Abstract

KEY MESSAGE

Introducing Agropyron cristatum chromosome 1P into common wheat can significantly reduce the plant height and leaf size, which can improve the plant architecture of common wheat. A new direction in crop breeding is the improvement of plant architecture for dense plantings to obtain higher yields. Wild relatives carry an abundant genetic variation that can increase the diversity of genes for crop genetic improvement. In this study, the A. cristatum 1P addition line, 1PS and 1PL telosomic addition lines were obtained by backcrossing the addition/substitution line II-3-1 (2n = 20'' W + 1P" + 2P") with the commercial recurrent parent cv. Jimai 22. Four continuous years of agronomic trait investigation in the genetic populations suggested that the introduction of A. cristatum chromosome 1P into wheat can significantly improve wheat plant architecture by reducing the plant height, leaf length and leaf width. A. cristatum chromosome arm 1PS reduced the plant height and leaf length of wheat, whereas introducing A. cristatum chromosome arm 1PL reduced the plant height, leaf length and leaf width. Altogether, our results demonstrated that A. cristatum chromosome 1P carries the dominant genes for small leaves and a dwarf habit for the enhancement of plant architecture in wheat. This study highlights wild relative donors as new gene resources for improving wheat plant architecture for dense planting.
