Effects of temperature and day length on cytoplasmic male sterility in cotton (Gossypium)

Abstract

Temperature and day length were shown to affect, to a major and minor degree respectively, the expression of male sterility in G. hirsutum stocks carrying G. anomalum or G. arboreum cytoplasms. Generally, sterility increased with increasing temperature and day length. Day temperatures above 33°C were required for the consistent expression of male sterility in the sterile A lines tested, while the maintainer, or B, lines became completely sterile at day temperatures above 36�. It was concluded that while the production of hybrid cotton seed by means of the sterile A lines currently available may be feasible in some tropical areas of Australia, it would be desirable to develop genotypes in which the cytoplasmic male sterile character is stable under a much wider set of temperature regimes.

The Effect of Temperature on Pollen Fertility and Anther Dehiscence of Cytoplasmic Male-Sterile Rye

“…Similarly, Wilson (1968) (Jensen 1962 resulted in almost full (96Vo) fertility (Marshall et al 1974).In onion, Jones and Clarke (1943) Bennekom (1969) found that all plants in a population ofonions were male-sterile at 14oC whereas at 30oC partially dehiscent and non-dehiscent anthers occurred in some spikes (Fig. 1) (Fig.…”

New insights into genotypic thermodependency of cytoplasmic male sterility for hybrid barley breeding

“…Detrimental effects of high temperatures on pollen viability were also described in Sorghum bicolor (Vara Prasad et al 2006) and tomato (Firon et al (2006). In cotton, Marshall et al (1974) found that sterility increased with increasing temperature and day length. Whereas temperatures above 33°C were required for the expression of CMS in A lines, maintainer lines (B lines) became completely sterile at temperatures above 36°C.…”

Cytoplasmic male sterility, resistance to gall mite and mildew, and season of leafing out in black currants

“…The regularity of transition from S to I as the season progresses suggests that temperature and probably nutritional status are involved, as in other genera (e.g. VAN DER MEER & VAN BENNEKOM, 1969;EDWARDSON, 1970;MARSHALL et al, 1974: SCOLES & EVANS, 1979. Differences in season of leafing out ( Table 5) and therefore of flowering, interacting with changeable spring temperatures could be a factor in the considerable variability in time of onset and development stage of the inflorescence at which the transition from S to I occurred.…”
