Morphological Characterization of a New and Easily Recognizable Nuclear Male Sterile Mutant of Sorghum (Sorghum bicolor)

Abstract: Sorghum (Sorghum bicolor L. Moench) is one of the most important grain crops in the world. The nuclear male sterility (NMS) trait, which is caused by mutations on the nuclear gene, is valuable for hybrid breeding and genetic studies. Several NMS mutants have been reported previously, but none of them were well characterized. Here, we present our detailed morphological characterization of a new and easily recognizable NMS sorghum mutant male sterile 8 (ms8) isolated from an elite inbred BTx623 mutagenized by et… Show more

“…The ms8 mutant was evaluated in Lubbock and in winter nurseries in Puerto Rico in 2014, 2015, and 2016. It exhibits a segregation of 1:3 of male sterile to fertile plants, which indicates that it is a single recessive stable male sterile mutant under both environments (Xin et al, 2017). The male sterility is also stable in the greenhouse under multiple day‐lengths and temperatures.…”

“…No. GS‐786, PI 682727), previously named male sterile 8 ( ms8 ), isolated from an ethyl methane sulfonate (EMS)‐mutagenized mutant library created in sorghum inbred line BTx623 (Xin et al, 2017). Unlike BTx623, the ms8 mutant produces tiny translucent anthers.…”

“…The diversity of these genetic resources is not fully exploited in terms of characterization, evaluation and documentation for utilization [23] [24]. Another reason could be the low number of researchers working on sorghum breeding [37]. According to literature only two researchers are working on sorghum breeding program in Namibia compared with China (200), India (150), Ethiopia (50) and Sudan (21) [11].…”
