SusCrop Call 1: Development of lodging-resistant and climate-smart rye - a contribution to a sustainable cereal production in marginal environments (RYE-SUS)
Project
Project code: JKI-ZL-08-3221
Contract period: 01.07.2019
- 30.06.2022
Purpose of research: Applied research
Plant architectural traits such as plant height are important targets to improve the yield potential of crops. The pre-competitive research and prototype demonstration in RYE-SUS makes use of hybrid breeding as a cutting-edge technology for plant improvement and genome-based precision breeding to increase targetspecific selection efficiency and accelerate breeding processes in rye. For the first time ever, we will develop semi-dwarf rye using the male sterility inducing Pampa cytoplasm and the dwarfing gene Ddw1. The new genotypes with an optimized harvest index will increase the yield potential mainly by exploiting heterosis as well as by mobilization of a larger part of the total plant assimilates to the grain, which improves the resource-use efficiency of rye. The genetically reduced gibberellin content of semi-dwarf rye results in new phenotypes and confers both lodging and drought tolerance, which strengthens the adaptation of rye to a changing climate. Lodging-resistant genotypes will considerably improve rye production by securing yield quantity and quality, saving cost and energy for grain drying, and reducing environmental impact by forgoing chemical growth regulators. We will use an effective restorer-of-fertility gene to minimise the costs of restoration in terms of grain yield. Consequently and as a further novelty to improve rye health and protection, every single semi-dwarf rye plant will produce pollen in amounts sufficient to minimise the risk of extremely toxic ergot alkaloids in the harvest. We will use a highly diagnostic field phenotyping platform representing target environments for rye production in Europe and Canada to proof the practical potential and to develop and exploit a simulation model of the growth and development of semi-dwarf as well as tall rye under potentially growth-limiting factors such as drought, frost, or nutrient deficiencies. This model will support novel integrated pest and crop management methods and practices for rye.
