Pyramiding panicle-level heat avoidance and grain-level heat tolerance improves rice grain appearance under high-temperature grain filling

Hirofumi Fukuda, Toshihiro Sakamoto, Jun‐ichi Yonemaru, Daisuke Ogawa

This study combines genetic loci for panicle-level heat avoidance and grain-level heat tolerance in rice to improve grain appearance under high-temperature conditions without reducing yield.

Dissecting Agronomically Favorable Genotypes in Temperate Japonica Rice via Haplotype Analysis of a Japan-MAGIC Population

Hirofumi Fukuda, Akari Fukuda, Toshihiro Sakamoto, Yoshihiro Kawahara, Ken Naito, Taiji Kawakatsu, Jun‐ichi Yonemaru, Daisuke Ogawa

The paper identifies favorable genotype combinations in temperate japonica rice using haplotype analysis of a multi-parent population, showing how specific variants improve yield and lodging tolerance.

Rice Cultivars Carrying the Semi Dwarfing Allele Enables High Yield without Lodging under Hairy Vetch based Green Manure

Hirofumi Fukuda, Toshihiro Sakamoto, Akari Fukuda, Daisuke Ogawa

The paper shows that rice cultivars with non-functional sd1/ga20ox2 alleles achieve high yield without lodging under hairy vetch green manure, comparable to chemical fertilizer systems.
