“…The number and main characteristics of two recessive nuclear male sterile lines (AH001A and AH003A) and four restorer lines (A1, A3, S5 and J10) are presented in Table 1. The two male sterile two-type lines (AH001AB and AH003AB) were determined by a single recessive gene and were obtained by backcross and sibling mating (Ye et al 2008a). There was no obvious difference in morphology between the male fertile and male sterile plants until the colored bud stage.…”

Eight cross combinations of Zinnia elegans were made using two recessive nuclear male sterile lines crossed with four restorers using the North Carolina Design II statistical method. Heterosis, combining ability and heritability was analysed using 12 horticultural traits and these demonstrated the advantage of heterosis in hybrid breeding of Zinnia elegans. Heterosis served to increase the number of whorls of ray florets across capitulum and the number of branches, and also decreased plant height, crown size, pedicel length and length of node. Thus, six horticultural traits were improved over mid parent and best parent status to fulfill major breeding goals of this herbaceous flower. The traits of plant height, number of whorls of ray florets across capitulum and pedicel length were primarily controlled by paternal additive effects, whereas crown size was mainly controlled by non-additive effects. Number of branches and length of node were affected both by paternal additive effects and non-additive effects. The ratio of general combining ability to specific combining ability indicated the importance of additive genes in the expression of these traits. Among the parental lines, AH003A and restorer A3 were chosen as primary female and male combiners, respectively. AH001A and restorer S5 were chosen as secondary combiners. The cross AH003A 9 A3 was determined as the most promising combination for producing potted plant characteristics, and AH001A 9 S5 was the best hybrid obtained in this study for cut flower traits. The analysis of combining ability for the parental lines showed that there was no causal relationship between general combining ability and specific combining ability effects.

“…Abnormal flower or bud development is a common phenomenon in male sterile plants, such as B. rapa L.ssp pekinensis (Guo et al, 2001), Zinnia elegans (Ye et al, 2008), B. napus L. (Dong et al, 2004), and Capsicum annum L. (He et al, 2008). In this study, the sequences of three flower-or bud-specific genes were detected in the 16 TDF homologous sequences, which indicated that altered flower or bud development may be an important process in Chinese cabbage multiple-allele nuclear genic male sterility.…”

ABSTRACT. To better understand the molecular mechanisms of multiple-allele-inherited male sterility in Chinese cabbage (Brassica rapa ssp pekinensis), differentially expressed genes in fertile and sterile plants must be isolated. We used cDNA-AFLP analysis to isolate differentially expressed genes in fertile and sterile buds of the twotype line, AB01. Sixteen high-quality sequences were generated, 11 of which were up-regulated in fertile buds, and five of which were upregulated in sterile buds. Based on BLAST screening and functional annotation, these genes have homology with genes encoding known flower-or bud-specific proteins, metabolism-related proteins and cellstructure proteins. In addition, the full-length cDNA sequences of the actin gene were cloned from the cabbage plants by RACE and used as an internal standard for semi-quantitative reverse transcription-PCR. Expression of three flower-or bud-specific differentially expressed transcript-derived fragments in fertile and sterile buds was examined using RT-PCR; the expression patterns of these genes were similar to the patterns observed in the cDNA-AFLP analysis.

“…The CGMS was developed in Carthamus tinctorius for commercial production of hybrids in India (Anjani 2005). Male sterile mutants have also been found in Hawaiian Bidens (Sun 1987), Taraxacum officinale (van der Hulst et al 2004), Tagetes erecta (He et al 2009(He et al , 2010, Hieracium alpinum (Mráz et al 2009), Chrysanthemum morifolium , Lactuca sativa (Hayashi et al 2011) and Zinnia elegans (Ye et al 2008).…”
