Pollen fertility and anther dehiscence of two cytoplasmic male-sterile lines of spring rye (Secale cereale L.), their maintainers, their restorers and the F1 between each sterile and restorer were investigated at three temperature regimes (15/10, 20/15 and 25/20 °C). In a second experiment, the anther dehiscence of five additional sterile/restorer hybrids was investigated at the same temperatures. Anthers of male-sterile plants did not contain pollen grains and were non-dehiscent at all temperatures. Pollen fertility of maintainer, restorer and sterile/restorer hybrids varied with temperatures. All anthers of maintainer and restorer lines were fully dehiscent, but partially dehiscent and non-dehiscent anthers occurred in the sterile/restorer hybrids. Anthers of florets in the upper and lower portions of spikes of the sterile/restorer hybrids were often partially dehiscent or non-dehiscent. Variation among tillers of a plant with respect to this character was low, but variation among plants of a sterile/restorer hybrid was high, suggesting genetic segregation. The classification of an anther as either dehiscent, partially dehiscent or non-dehiscent was directly related to pollen fertility. Better restoration of fertility was obtained at temperatures of 20/15 or 25/20 °C than at 15/10 °C.

Abstract Background A cytoplasm of CW-type cytoplasmic male sterile (CMS) line is derived from Oryza rufipogon strain W1 and fertility is restored by a single nuclear gene, Rf17. We have previously reported that CW-CMS were effective for breeding CMS lines of Indica Group rice cultivars, IR 24 and IR 64. The applicability of this CW-CMS/Rf17 system to produce other elite Indica Group rice cultivars with CMS was explored. Findings Out of seven elite Indica Group rice cultivars, complete CMS lines were obtained for six cultivars: NSIC Rc 160, NSIC Rc 240, Ciherang, BRRI dhan 29, NERICA-L-19, and Pusa Basmati. The fertility of these six lines was restored when Rf17 was present. A CMS line was not obtained for the cultivar Samba Mahsuri. Conclusions The CW-CMS/Rf17 system will be useful to produce CMS lines and restorer lines of various elite Indica Group rice cultivars.
