Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Fineness of Cement

Fineness of Cement

The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.

The R Chart

The R Chart

In statistical process control, control charts, particularly R charts, are instrumental in monitoring process variations and identifying non-random patterns that run charts might miss. R charts track the variability within process subgroups, which is crucial when standard deviation use is impractical or unknown process variations exist.
R charts are pivotal for pinpointing shifts in process variability. Stability is indicated when all data points remain within the defined upper and lower...

Wilcoxon Signed-Ranks Test for Median of Single Population

Wilcoxon Signed-Ranks Test for Median of Single Population

The Wilcoxon signed-rank test for the median of a single population is a nonparametric test used to evaluate whether the median of a population differs from a specified value. Unlike parametric tests, it does not require data to follow a normal distribution, making it suitable for non-normal or small samples. The test begins by calculating the difference (d) between each observation and the hypothesized median. The absolute values of these differences are ranked in ascending order, with ties...

Factors Affecting Workability

Factors Affecting Workability

The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...

Summary

Rice varieties Chenmaai and Goamibyeo are best for bread making. Intermediate amylose content (AC) and low water absorption index (WAI) are key indicators for quality rice bread flour.

Area of Science:

Food Science
Agricultural Science
Cereal Chemistry

Background:

Predicting rice bread quality solely from amylose content (AC) or dough properties is challenging.
Rice breeding programs require reliable methods to assess the bread-making potential of new varieties.
Understanding the relationship between rice characteristics and bread quality is crucial for cultivar selection.

Purpose of the Study:

To investigate the relationship between amylose content (AC) and bread baking quality in Korean rice varieties.
To identify specific rice flour characteristics that contribute to superior rice bread quality.
To provide insights for selecting optimal rice cultivars for bread production.

Main Methods:

Categorization of rice varieties based on amylose content (AC) into low, intermediate, and high groups.
Measurement of water absorption index (WAI) and gelatinisation enthalpy for different rice flours.
Evaluation of bread volume, crumb texture, and firmness after 7 days of storage.

Main Results:

Rice varieties were classified by AC: low (Manmibyeo, Jinsumi, Seolgaeng, Hanareumbyeo), intermediate (YR24088 Acp9, Suweon517, Chenmaai, Goamibyeo), and high (Milyang261).
High WAI was observed in Suweon517, Milyang261, and Manmibyeo; low WAI in Goamibyeo, YR24088 Acp9, Jinsumi, Seolgaeng, Hanareumbyeo, and Chenmaai.
Chenmaai and Goamibyeo demonstrated the most suitable characteristics for bread making, exhibiting good volume and texture.

Conclusions:

Chenmaai and Goamibyeo are the most appropriate rice varieties for bread production based on volume, texture, and crumb firmness.
Intermediate AC and low WAI are identified as primary indicators for high-quality rice bread flour.
These findings aid in the selection of rice cultivars for improved bread-making performance.
