Journal ArticleDOI
Mating Design and Genetic Structure of a Multi-Parent Advanced Generation Intercross (MAGIC) Population of Sorghum (Sorghum bicolor (L.) Moench).
Patrick Obia Ongom,Gebisa Ejeta +1 more
TL;DR: The mating design and structure of the first MAGIC population in sorghum was described, found to be rich in allelic content with high fragmentation of its genome, making it fit for both gene mapping and effective marker-assisted breeding.
Journal ArticleDOI
Targeted mutagenesis of a conserved anther-expressed P450 gene confers male sterility in monocots.
A. Mark Cigan,Manjit Singh,Geoffrey Benn,Lanie Feigenbutz,Manish Kumar,Myeong-Je Cho,Sergei Svitashev,Joshua Young +7 more
TL;DR: A custom designed homing endonuclease, Ems26+, was used to generate in planta mutations in the rice, sorghum and wheat orthologs of maize Ms26, which prevents pollen formation resulting in male sterile plants and fertility was restored in Sorghum using a transformed copy of maizeMs26.
Sorghum Grain Mold
R. P. Thakur,Belum V. S. Reddy,S. Indira,V. P. Rao,Shrishail S. Navi,Xiao-Bing Yang,S. Ramesh +6 more
TL;DR: In this bulletin, attempts have been made to briefly describe the important findings of research done at ICRISAT and elsewhere, and to emphasize some of the recent developments on management of grain mold, including refined screening techniques, sources of resistance, genetics and mechanisms of resistances, and other management options, including an integrated management approach.

Combining ability and heterosis as influenced by male-sterility inducing cytoplasms in sorghum [Sorghum bicolor (L.) Moench]
TL;DR: The results revealed that cytoplasm and its first-order interaction with year, R- and A-lines did not appear to contribute to variation in iso-nuclear hybrids for plant height and grain yield, and A2 CMS system is as efficient as A1 with a slight edge over A1 for commercial exploitation.
Sorghum Hybrid Parents Research at ICRISAT–Strategies, Status, and Impacts
TL;DR: A large number of hybrids have been developed and released/marketed for commercial cultivation in Asia, the Americas, Australia and Africa and have contributed significantly to increase grain and forage yields in several countries.

Forage yield, quality, and fertility of sorghum sudan grass hybrids in A1 and A3 cytoplasm
Jeffrey F. Pedersen,J. J. Toy +1 more
TL;DR: The objectives of this study were to compare the effects of A1 and A3 cytoplasm on the maturity, fertility, height, forage yield, and forage quality of sorghum x sudangrass hybrids.
Journal ArticleDOI
Effect of cytoplasmic male-sterility in sorghum on host plant interaction with sorghum midge, Contarinia sorghicola
TL;DR: Differences in midge damage and the number of midges emerged were not significant between the midge-resistant andMidge-susceptible A-lines when infested without pollination (except midge emergence on PM 7061A).
Journal ArticleDOI
Cytoplasmic male-sterility and source of pollen influence the expression of resistance to sorghum midge, Stenodiplosis sorghicola
TL;DR: Findings will have an important bearing on the production of hybrids with resistance to insects, as male-sterile lines of the both midge-resistant andMidge-susceptible lines were equally susceptible, indicating that resistance to sorghum midge is influenced by factors in the cytoplasm of the B-line.
Journal ArticleDOI
Mitochondrial ATP synthase genes may be implicated in cytoplasmic male sterility inSorghum bicolor
TL;DR: It is proposed that incompatibility in nuclear cytoplasmic interactions may be explained in terms of incompatible subunits being synthesized by the mitochondria and nucleus for a multisubunit complex of the mitochondrial membrane such as ATPase.
Alternate cytoplasms and apomixis of sorghum and pearl millet
K F Schertz,S Sivaramakrishnan,W W Hanna,J Mullet,Y Sun,U R Murty,D R Pring,K N Rai,B V S Reddy +8 more
TL;DR: Current research to determine the cause and control of sterility-inducing cytoplasmic-nuclear male sterility in sorghum and pearl millet could lead to greater efficiency and effectiveness in using CMS to select parents and produce hybrids.
