“…It is generally used as spray for production of male sterile lines at commercial level. SQ-1 has been used to induced male sterility in wheat (Liu et al, 2018), common millet (Cui, 2008), 95-100 % male sterility by spraying at an optimum dosage in foxtail (Song et al, 2011;Zhang et al, 2017), > 90 % male sterility at 5.0 kg ha-1 in Maize (Wei et al, 2012).…”

“…Both species possess several significant advantages over related C4 panicoid grasses such as maize and sorghum, including short life cycle, small size, simple growth requirements and ease of transformation ( Brutnell et al, 2010 ). Difficulties with making controlled crosses between accessions, owing to small size of the individual flowers, has been addressed successfully by both temperature and chemical interventions to kill pollen in the female parent ( Jiang et al, 2013 ; Zhang H.Y. et al, 2017 ), and much work has also been done on overcoming seed dormancy issues ( Sebastian et al, 2014 ; Brenner et al, 2015 ; Acharya et al, 2017 ).…”

Setaria viridis (green foxtail) and its domesticated relative S. italica (foxtail millet) are diploid C4 panicoid grasses that are being developed as model systems for studying grass genomics, genetics, development, and evolution. According to archeological evidence, foxtail millet was domesticated from green foxtail approximately 9,000 to 6,000 YBP in China. Under long-term human selection, domesticated foxtail millet developed many traits adapted to human cultivation and agricultural production. In comparison with its wild ancestor, foxtail millet has fewer vegetative branches, reduced grain shattering, delayed flowering time and less photoperiod sensitivity. Foxtail millet is the only present-day crop in the genus Setaria, although archeological records suggest that other species were domesticated and later abandoned in the last 10,000 years. We present an overview of domestication in foxtail millet, by reviewing recent studies on the genetic regulation of several domesticated traits in foxtail millet and discuss how the foxtail millet and green foxtail system could be further developed to both better understand its domestication history, and to provide more tools for future breeding efforts.

Analysis of effects of trifluoromethanesulfonamide in sorghum inbred lines and their derived hybrids

In sorghum [Sorghum bicolor (L.) Moench], development of male‐sterile versions (A‐lines) of the seed parents (B‐lines) is a tedious and time‐consuming process limiting opportunities for the improvement of new seed parents. Assessment of the value of a potential new seed parent requires testcross hybrid evaluations, but because of male fertility of these lines, conventional methods are inadequate to generate hybrid seed required for testing. Mechanisms to reduce the number of lines that require sterilization would be beneficial. The chemical gametocide trifluoromethanesulfonamide (TFMSA) was evaluated for its potential applicability to generate testcross hybrid seed. To study the effect on inbred line productivity, foliar applications of 25 mg of TFMSA were made to a select set of male‐fertile B‐lines and were compared to the corresponding untreated male‐sterile A‐line. Trifluoromethanesulfonamide induced near‐complete male‐sterility and allowed for testcross hybrid seed production across a range of genotypes. Comparison to untreated B‐lines indicated an average 3‐d delay in flowering and a 13‐cm reduction in plant height. Furthermore, average seed weight per panicle (productivity) was reduced by 8 g. Comparison of testcross hybrids produced by TFMSA induced male‐sterile lines and cytoplasmic male‐sterile lines did not reveal any significant and meaningful differences between the hybrids derived from both sterility systems. Moreover, inbred lines produced hybrids that ranked consistently in both systems. These results show TFMSA can affect productivity of treated inbred lines, but not the derived hybrid, which demonstrates that TFMSA can be used to produce hybrids for evaluation prior to investment in sterilizing of these lines.
