abstract = {Pollen sterility (PS) in mother lines is crucial for hybrid crossings in plant breeding. 21 di-- (2x) and tetraploid (4x) accessions of the hermaphroditic chamomile were screened for spontaneous, thermic or gametocide induced PS. Two crossing trials with the diploid accessions 'Bona' (BON) and 'Hungary 2' (HUN2) should specify maternally inherited cytoplasmic male sterility (CMS). Progeny thereof showed increased PS. BON as mother (BH) entailed means of 30 and 22% PS, versus 8% and 20% after reciprocal crossings. Backcrosses of BH with HUN2 in paternal and maternal direction revealed increasing mean PS (24% and 32%), without verification of CMS. A split plot design of 100 individuals treated with four chemical gametocides analyzed PS, seed set, germination rate and whole plant damage. Tri--iodobenzoic acid caused the highest PS (43%). Progeny of two plants (2x, 4x) with degenerated anthers without pollen, showed 100% PS either in tetraploid F1 and F2 (4% and 11%) or in diploid F2 and F3 (26% and 23%). High temperature (30/28°C day/night) decreased the male fertility to some extent.},

abstract = {Interploid crosses display a common approach in plant breeding to vary ploidy level in crops. This research included three trials to determine ploidy purity and genomic stability of diploid, triploid and auto-tetraploid varieties of German chamomile during life-time and across generations after interploid crosses. Impacts of auxin application were evaluated for seed set, germination rate and progeny ploidy. Ploidy was assessed by flow cytometry and chromosome counting. Ploidy purity in cultivars ranged from 64% (‘Lutea’, 4x) to 100% (‘Bona’, 2x), the share of ploidy-deviants was in 4x-cultivars higher (8%) than in 2x (1%). Auxin application resulted in higher seed set in tetraploids only, while the number of progeny did neither depend on cross direction nor on auxin application. Life time genome stability applied for all ploidy levels. Ploidy level of progeny from 2x × 4x crosses was mostly linked to the maternal level. 3x plants bore progeny with diverse ploidy forms, but not with triploidy. However, cultivars should regularly be monitored for conformance to declared ploidy also in awareness of possible unintended contamination.},
