Enhancing rice yield in upland rice systems through genetic improvement remains a major
challenge in the tropics. This review aims to provide the trends on upland rice cultivation …

World population is projected to reach its maximum (∼ 10 billion people) by the year 2050.
This 45% increase of the current world population (approaching seven billion people) will …

Background Drought is one of the most important abiotic stresses causing drastic reductions
in yield in rainfed rice environments. The suitability of grain yield (GY) under drought as a …

Background Rice (Oryza sativa L.) is a highly drought sensitive crop, and most semi dwarf
rice varieties suffer severe yield losses from reproductive stage drought stress. The genetic …

Background Drought is one of the most important abiotic stresses that cause drastic
reduction in rice grain yield (GY) in rainfed environments. The identification and …

Maize (Zea mays L.) yields in southern Africa are low, due largely to drought and low‐N
stress. Selection of stress‐tolerant genotypes by CIMMYT is conducted indirectly under …

Abstract Rice (Oryza sativa L.), the major staple food crop of the world, faces a severe threat
from widespread drought. The development of drought-tolerant rice varieties is considered a …

The complexity of genotype× environment interactions under drought reduces heritability,
which determines the effectiveness of selection for drought tolerance and development of …

Altering root morphology of rice (Oryza sativa L.) cultivars could improve yields in drought-
prone upland ecosystems. Marker-assisted backcross breeding was used to introgress four …

Rice, the world's most important food crop, has been grown for more than 6000 years in
South Asia. Wild rice, however, grew in the Himalayas 15,000-16,000 years back. Currently …
