Genetic and Cytoplasmic‐Nuclear Male Sterility in Sorghum

Inheritance and molecular mapping of Rf6 locus with pollen fertility restoration ability on A1 and A2 cytoplasms in sorghum

“…Despite the availability of diverse alternate CMS systems, hybrid vigor is exploited mainly using milo (A 1 ) cytoplasm. Several factors such as stability of male-sterility, availability of elite restorers, effect of cytoplasm on agronomic traits and the availability of commercially viable heterosis influence the usefulness of these non-milo CMS systems at a commercial level [14,15]. Of the several A 1 alternative CMS systems described, A 2 was better for commercial exploitation [15,16].…”

Application of LW7 marker for identification of progenies with male sterility gene in sweet sorghum population

“…Since the discovery of male sterility in sorghum (Stephens and Holland 1954), hybrid varieties have been used extensively for grain sorghum. An attempt to converse male sterility into sweet sorghum has been made (Reddy et al 2010b); moreover, the research on heterosis among germplasm accessions (Pfeiffer et al 2010) and related species has also been carried out , Wang et al 2009). Some experimental hybrids of A 3 male sterility showed better performance for brix and stalk yield than their parents (Pfeiffer et al 2010); additionally, Makanda et al (2009) reported that the hybrids had performance for brix higher than parents and exhibited heterosis of up to 112%.…”

Combining ability of CMS-lines of grain sorghum based on A1, A2, A3, A4, 9E and M-35-1A types of сytoplasmic male sterility

“…У сорго известно большое количество ЦМС-индуцирующих цитоплазм -А1, А2, А3, А4, А5, А6, 9Е, М-35-1А и др. (Reddy et al, 2005). На основании этого селекционеры включают в схемы скрещиваний ЦМС-линии с новыми типами стерильности -А2 и А3 (Mohammed, 2009;Reddy et al, 2009;Aruna et al, 2013; Гаршин и др., 2014), А4, 9Е и М-35-1А (Кибальник, Эльконин, 2014; Кибальник, 2016).…”
