TLDR
The results obtained allowed us to assess the significance or otherwise of cytoplasmic differences in respect of gca effects of the A-lines and the mean performance and sca effects ofThe hybrids by comparing with the least disadvantaged groups.Abstract:
days to 50% flowering, plant height, grain yield and 100grain weight (g). Statistical analysis. Analysis of variance (ANOVA) was carried out as per SSPD. The general combining ability (gca) effects of the parents and the specific combining ability (sca) effects of the crosses were estimated as per Kempthorne (1957). The significance or otherwise of cytoplasmic differences in respect of gca effects of the A-lines and the mean performance and sca effects of the hybrids was determined by comparing with the leastread more

Cytoplasmic male sterility (CMS) in hybrid breeding in field crops
TL;DR: The status of diverse sterility-inducing cytoplasms and associated Rf factors reported across different field crops are reviewed along with exploring opportunities for integrating modern omics tools with CMS-based hybrid breeding.

Inheritance and molecular mapping of Rf6 locus with pollen fertility restoration ability on A1 and A2 cytoplasms in sorghum.
TL;DR: This work mapped a major male fertility restoration locus on sorghum chromosome 4 tightly linked with SSR markers, SB2387 and SB2388, and identified six genes including a pentatricopeptide repeat (PPR) gene, Sobic that could be a candidate for fertility restoration on A1 and A2 cytoplasms.

GENETIC ANALYSIS OF CMS BASED HYBRIDS AND THEIR PARENTS IN FODDER SORGHUM [Sorghum bicolor (L.), Moench
TL;DR: The analysis of variance for experimental design revealed that the mean squares due to genotypes, parents and hybrids were highly significant for all the characters indicating that experimental material had sufficient genetic variability for all of the characters.

Heterosis: Feeding People and Protecting Natural Resources
TL;DR: The purpose of this analysis will be to show how hybrids and heterosis can help to supply food for burgeoning populations and also help to improve environmental health of the global food production system.

Cytoplasmic Male‐Sterility For Hybrid Sorghum Seed Production1
J. C. Stephens,R. F. Holland +1 more
TL;DR: All possible crosses between heterozygous (Msms) Day, Double Dwarf Yellow Sooner milo and Texas Blackhull kafir were made to determine if cytoplasmic factors might account for the F, male-sterility in the combination of msms Day x kafIR, and the evidence indicated that theF, sterility was genetic rather than cytop lasmic.
