Background Segregation distortion (SD) is a frequently observed occurrence in mapping
populations generated from crosses involving divergent genotypes. In the present study, ten …

Supplying sufficient rice to growing populations is a global challenge. Hybrid indica rice
varieties exploiting heterosis have increased yields, but inter-subspecific crosses between …

The accumulation of independent mutations over time in two populations often leads to
reproductive isolation. Reproductive isolation between diverging populations may be …

Male sterility is an important trait for crop breeding program based on heterosis. Recent
advances in molecular researches have led to the identification of genes involved in plant …

The two-line system has been widely used in hybrid rice seed production, and the reverse
photoperiod-sensitive genic male sterile line is a new germplasm with an opposite …

Understanding the morphological and physiological characteristics which are attributable to
determine indica and japonica subspecies of Asian rice (Oryza sativa L.) is important to …

Hybrid sterility is the major obstacle that can act as a barrier to genetic recombination and
limits favorable gene transfer during inter-subspecific crosses in rice. However, hybrid …

Rice (Oryza sativa L.) is consisted of two subspecies, indica and japonica. Indica rice is
known to be adaptable in tropical conditions, and japonica rice for temperate conditions …

Supplying sufficient rice to growing populations is a global challenge. Hybrid indica rice
varieties exploiting heterosis have increased yields, but inter-subspecific crosses between …

Low temperature or cold stress is one of the major abiotic stresses limiting rice (Oryza sativa
L.) production and productivity in the high altitude of Madagascar; it is affecting an estimated …
