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.
Journal ArticleDOI
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.

Journal ArticleDOI
Cosegregation of Single Genes Associated with Fertility Restoration and Transcript Processing of Sorghum Mitochondrial orf107 and urf209
TL;DR: It is concluded that the nuclear gene(s) conferring enhanced orf107 and urf209 processing activities are tightly linked in IS1112C.
Journal ArticleDOI
Genetic diversity among elite sorghum inbred lines assessed with DNA markers and pedigree information
D. Ahnert,M. Lee,David F. Austin,C. Livini,W. L. Woodman,S. J. Openshaw,J. S. C. Smith,K. Porter,G. Dalton +8 more
TL;DR: Cluster analysis of GS estimates from the entire set of inbreds revealed separate groups for R- and B-lines in agreement with parental types, pedigree information, and the classification system used by breeders.
Journal ArticleDOI
Nuclear-mitochondrial interactions in cytoplasmic male-sterile sorghum.
TL;DR: It is indicated that nuclear-mitochondrial interactions are required for regulation of mitochondrial gene expression in male fertile and sterile nuclear-cytoplasmic combinations of sorghum.
Journal ArticleDOI
Recovery of heritable, transposon-induced, mutant alleles of the rf 2 nuclear restorer of T-cytoplasm maize.
TL;DR: Pedigrees and restriction fragment length polymorphism (RFLP)-based analyses indicated that all seven rf 2-m alleles were derived independently, suggesting that Rf2 alleles produce a functional product necessary to restore pollen fertility to cmsT.
Journal ArticleDOI
RFLP mapping of the maize gametophytic restorer-of-fertility locus (rf3) and aberrant pollen transmission of the nonrestoring rf3 allele
TL;DR: Using 2L RFLPs and three-point mapping analysis, it is shown that the rf3 locus is located on the long arm of maize chromosome two and that Rf3/rf3 CMS-S plants may aberrantly transmit the nonrestoring allele, rF3, through the male gametophyte.
