Auxin Application at the Flowering Stage of Rice Alleviates the Negative Impact of Heat Stress on Spikelet Fertility and Yield Attributes [PDF]

open access: goldAgriculture, 2023
The reproductive stage of rice is vulnerable to heat stress, which reduces spikelet fertility and yield. Auxin significantly influences reproductive development, hence the research aimed to enhance spikelet fertility and grain attributes in rice plants ...

Assessing the Genetic Improvement in Inbred Late Rice against Chilling Stress: Consequences for Spikelet Fertility, Pollen Viability and Anther Characteristics [PDF]

open access: goldAgronomy, 2022
The development of varieties with strong tolerance is one of the important strategies to diminish the negative impact of chilling stress during heading on the spikelet fertility and yield formation of late-season rice.

Study on the impact of mutagenic treatment on pollen and spikelet fertility and its relationship in rice (Oryza sativa L.)

open access: diamondElectronic Journal of Plant Breeding, 2019
The present study was conducted to study the impact of different mutagens on pollen and spikelet fertility. Pollen fertility and spikelet fertility per cent was found to be inversely proportional to increasing dose of the mutagen in all the treatments ...

Enclosed stigma contributes to higher spikelet fertility for rice (Oryza sativa L.) subjected to heat stress

open access: diamondCrop Journal, 2019
With global warming, rice plants may be subjected to heat stress more regularly during the heat-sensitive flowering stage, causing spikelet sterility and grain yield loss.

Evaluation of the impact of heat stress at flowering on spikelet fertility and grain quality in barley

open access: diamondAgriculture Communications
Against the backdrop of a warming climate, heat stress has become one of the most limiting factors to crop productivity and food security worldwide. The flowering stage is susceptible to high temperatures in cereal crops, leading to severe grain yield ...

Screening for Spikelet Fertility and Validation of Heat Tolerance in a Large Rice Mutant Population

open access: yesRice Science, 2019
A total of 10 000 M4 individuals in Jao Hom Nil (JHN) mutant population was treated with high temperature (40 °C to 45 °C) during the day time (6 h) from the booting to the harvesting stages, and ambient temperature (33 °C to 35 °C) was used as the ...

Elevated CO2 Could Reduce Spikelet Fertility and Grain Appearance Quality of Rice(Oryza sativa L.) Grown under High-temperature Conditions

open access: diamondAsian Journal of Atmospheric Environment, 2022
Two Japanese rice cultivars with different heat-tolerance, Hinohikari (sensitive) and Nikomaru (tolerant), were grown in pots inside open-top chambers and exposed to ambient CO2 (400 µmol mol−1) or elevated CO2 (550 µmol mol−1) from the beginning of the ...

Pollen fertility Vs Spikelet fertility in F2 of a CMS based hybrids in rice (Oryza sativa L.) under Aerobic condition [PDF]

open access: greenElectronic Journal of Plant Breeding, 2010
Identification of maintainer and restorers from rice germplasm through test crossing is the initial step in three line heterosisbreeding. Maintainer lines can be converted into cytoplasmic male sterile lines to utilize in development of rice hybrids ...

Introgression of QTLs Controlling Spikelet Fertility Maintains Membrane Integrity and Grain Yield in Improved White Ponni Derived Progenies Exposed to Heat Stress

open access: diamondTheoretical and Applied Genetics, 2017
This study fine mapped and validated a QTL on rice chromosome 4 that increases spikelet fertility under high temperature (over 37 °C) at the flowering stage. Climate change has a negative effect on crop production and food security. Understanding the genetic mechanism of heat tolerance and developing heat-tolerant varieties is essential to cope with ...
