TL;DR: It is suggested that variations in flowering time, potential yields and drought patterns need to be considered for development of drought-resistant cultivars using specific physiological traits.

TL;DR: Under less severe and prolonged drought conditions, genotypes that could achieve higher plant dry matter at anthesis were desirable and had less delay in flowering, higher grain yield and higher drought response index, indicating the importance of ability to grow during the prolonged stress period.

TL;DR: The nature of genotype by environment (G × E) interactions in rainfed lowland rice was examined using data for 37 genotypes across 36 environments in India, Bangladesh, Thailand, Indonesia and the Philippines from 1994 to 1997 to discuss implications for choice and management of testing sites, and identification of suitable reference lines for the breeding program.

TL;DR: The magnitude and nature of genotype-by-environment (G x E) interactions for grain yield, days-to-flower and plant height of rainfed lowland rice in Northeast Thailand were examined using random F-7 lines from seven crosses developed by the Thai breeding program, indicating that yield ofRainfed low land rice could be improved above that of the popular cultivars.

TL;DR: Past work on characterising the variability in the physical environment, and rice production in the rainfed lowland ecosystem are reviewed and possible connections between this variability and slow progress in developing new cultivars that are widely adapted to the rain fed lowland rice ecosystem are examined.
