BACKGROUND The use of cytoplasmic male sterility (CMS) in F1 hybrid seed production of chili pepper is increasingly popular. However, the molecular mechanisms of cytoplasmic male sterility and fertility restoration remain poorly understood due to limited transcriptomic and genomic data. Therefore, we analyzed the difference between a CMS line 121A and its near-isogenic restorer line 121C in tra...

Identification of desirable maintainers and potential restorers in a hybrid rice breeding program is the dire need for development hybrids. Seventeen (17) cytoplasmic male sterile (CMS) lines (15 imported from IRRI 02 locally developed by RRI, KSK) were crossed with one hundred sixty (160) testers to identify their genetic nature behave as restorer or maintainer year 2017 2018. A total test cro...

Twenty-one hybrids of sunflower were produced by crossing 7 introduced cytoplasmic male sterile lines (CMS-lines) with 3 restorer (RF-lines) using line × tester mating design. The twenty-one hybrids, three restorers, seven maintainer (B-lines) evaluated. experiment was conducted in a randomized complete block design replications. Mean squares due to genotypes, parents (P), crosses (C), (L), tes...

In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

Identifying the best inbred combinations for the development of commercial hybrid of sunflower remains the main challenge to sunflower breeders. In the present research the level of heterosis of F1 hybrids, genetic diversity of parental lines based on SSR markers, as well as its connection with specific combining ability of sunflower were studied. Ten sunflower elite inbred lines (3 restorer li...
