Title
The Impact of Herbicide-Resistant Rice and Hybrid Rice Technology on Weedy Rice Evolution
Vijay Pratap Singh Journal of the Arkansas Academy of Science 2015
Other claims from this paper (16)
- Observation Seventy-nine percent of weedy rice accessions were resistant to imazethapyr.
- Observation Accessions resistant to imazethapyr harbored the S653N mutation.
- Observation The herbicide-resistant weedy rice accessions were outcrosses of ClearfieldTM rice and weedy rice.
- Observation Nearly 70% of herbicide-resistant weedy rice flowered at the same time as ClearfieldTM rice.
- Observation Seed shattering was greatly reduced in progenies of some herbicide-resistant weedy rice accessions (15 to 87%).
- Observation Kernels of 20% of the parent accessions had segregating white and red bran color.
- Observation Two goldhull parent accessions were homozygous for white bran and gave 100% white-bran progenies.
- Intervention effect Winter flooding reduced the germination of rice seed by 40-50% after 130-160 d of burial.
- Association Hybrid rice seed had a higher capability to survive the winter (13-53% viability) than inbred rice seed (8-27%).
- Association Hybrid rice is expected to leave more volunteer rice in the field than inbred rice.
- Association Fields with a cropping history of hybrid rice had higher volunteer rice infestation (20%) than fields planted only with inbred rice (5.6%).
- Association Total grain yield of rice was reduced by 0.4% for every 1% increase in volunteer rice density.
- Association The 1000-kernel weight, kernel length-width ratio and %protein of rice were affected by volunteer rice density.
- Association The %amylose and head rice yield of rice were affected by volunteer rice density.
- Intervention effect Pyroxasulfone applied in the fall followed by 2,4-D caused minimal (6%) crop injury.
- Intervention effect The fall pyroxasulfone plus 2,4-D treatment did not reduce rice yield.
