Effects of Two Sowing Methods on the Growth, Yield, and Quality of Hybrid Rice under Mechanical Transplantation

Agronomy, 2023
Poor adaptability of hybrid-rice (Oryza sativa L.) mechanical transplanting is one of the main factors limiting hybrid-rice production. Mixed sowing ensured stronger seedlings and better mechanical transplanting quality than conventional sowing in ...

Genetic Analysis of S5 Regulating the Hybrid Sterility between Indica and Japonica Subspecies in Rice

Agronomy, 2023
Hybrid sterility is the major obstacle to the utilization of inter-subspecific heterosis in hybrid rice breeding. The S5 locus, composed of three adjacent genes ORF3, ORF4, and ORF5, plays a crucial role in regulating indica/japonica hybrids’ female ...

Relationship of Parental Indica-Japonica Indexes with Yield and Grain Quality Traits of Japonica Hybrid Rice in Northern China

Rice Science, 2010
Abstract Taking the main parents (10 male sterile lines and 10 restorer lines) and their 100 combinations of japonica hybrid rice in northern China as materials, the relationships of parental indica-japonica indexes determined by the methods of the Cheng's index as well as simple sequence repeat (SSR) markers with yield and grain quality traits of ...

Natural variation in OsMYB8 confers diurnal floret opening time divergence between indica and japonica subspecies

Nature Communications
The inter-subspecific indica-japonica hybrid rice confer potential higher yield than the widely used indica-indica intra-subspecific hybrid rice. Nevertheless, the utilization of this strong heterosis is currently hindered by asynchronous diurnal floret ...
