Male sterility induced by the chemical hybridizing agent clofencet on wheat, Triticum aestivum and T. turgidum var. durum

The objective of this experiment was to evalúate the male sterilizing activity induced by the chemical hybridizing agent (CHA) clofencet, on four wheat varieties: two Triticum aestivum cultivars, 'Pia' and 'Claudia', and two Triticum turgidum var. durum cultivars, 'Capri...

The CHA was sprayed at two stages of the Feekes scale, 7.5 and 8.5, using four rates of active ingredients (0, 3.5, 5.0 and 6.5 kg-ha4) in a split block design with five replicates. The efficiency of the treatments was determined by measuring developed seeds and calculating male sterility (MS). Results showed that MS increased with increasing dosage and was more pronounced at the latest stage of development. The MS average for the highest dosage was 47.3% in the first stage of application and reached 84% at the second stage of application. Cultivars responded differently to the CHA, but no differences clearly attributable to species could be detected. T. aestivum cultivar 'Pia' reached 96% MS, a value that justifies the use of clofencet as a CHA for hybrid wheat production. The insufficient levels of MS detected in the other cultivars were due to causes not determined in this study.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Chile.
