Genetic Stability in Triticale Measured by Pollen Viability

1,000 pollen grains were analyzed per genotype in a study by Embrapa Wheat to infer genetic stability. The research assessed hexaploid triticale genotypes in a Brazilian breeding program using optical microscopy and acetic carmine staining. Data includes counts of binucleate and trinucleate pollen grains, grains with little starch, empty grains, and those with more than one pore or different sizes.

Use Cases

• Selecting stable parent genotypes for breeding programs based on pollen viability percentages.
• Comparing cytogenetic characteristics like binucleate vs. trinucleate pollen grain counts across genotypes.
• Informing crossing and backcrossing strategies in crop breeding using pollen quality metrics.

Strengths

• Analysis includes 1,000 pollen grains per genotype, providing a substantial sample size.
• Variables measured include multiple cytogenetic traits such as pollen grain nucleation and starch content.
• Statistical analysis was performed using ANOVA and Tukey's test at a 1% significance level.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
