The heading date is a vital factor in achieving a full rice yield. Cultivars with particular flowering behaviors have been artificially selected to survive in the long-day and low-temperature conditions of Northeast China. To dissect the genetic mechanism responsible for heading date in rice populations from Northeast China, association mapping was performed to identify major controlling loci. ...

In vivo doubled haploid (DH) production based on crossing heterozygous germplasm with mtl inducer lines promises to transform modern rice (Oryza sativa) breeding. However, this technology is limited, as inducers and pollen acceptors have asynchronous heading dates. To address obstacle, we developed a panel of multiple-heading-date that produce for more than 35 days. We edited the MTL gene in hy...

An experiment was conducted at Rasht Rice Research Institute, in 2001 to study trait relationships and to determine the direct and indirect effects of different characteristics on grain yield of rice (Orgza sativa L.). A 9x2 factorial experiment in complete randomized block design with 3 replications was used. The two factors were 9 cultivars, namely: Hashemi, Ali Kazemi, Binam, Sepeedroud, Nem...

Photoperiod and temperature are two important environmental factors that influence the heading-date of rice. Although the influence of the photoperiod on heading has been extensively reported in rice, the molecular mechanism for the temperature control of heading remains unknown. This study reports an early heading mutant derived from tissue culture lines of rice and investigates the heading-da...

In wheat (Triticum aestivum L.), time from planting to spike emergence is influenced by genes controlling vernalization requirement and photoperiod response. Characterizing the available genetic diversity of known and novel alleles of VERNALIZATION1 (VRN1) and PHOTOPERIOD1 (PPD1) in winter wheat can inform approaches for breeding climate resilient cultivars. This study identified QTL for headin...

Selection for heading date has been a decisive factor to increase areas cropped with oats in Brazil. Although important oat breeders, genomic regions controlling have not completely identified. The objective of this study was identify subtropical environments. A set 412 genotypes, developed from 1974 2015, assessed contrasting environments and genotyped using genotyping–by–sequencing (GBS). Phe...
