“…Thus, yield traits such as effective tillers hill -1 , total spikelets panicle -1 , filled grains panicle -1 , 1000-grain weight, % sterility and grain yield hill -1 are the most popular parameters used to identify droughttolerance in rice breeding programs. The findings are in harmony with those of Yang et al (2001) ; Venuprasad et al (2008) and Wang et al (2010) who have stressed upon taking into account of different agronomic parameters during screening of rice varieties or while developing new rice varieties for drought prone areas. …”

“…leaf rolling, leaf chlorosis and green leaf area have been well established (Cabuslay et al, 2002;Bernier et al, 2008). Moreover, yield traits, such as grain yield, productivity and grain sterility are the most popular parameters used to identify water deficit tolerance in rice breeding programs (Fukai et al, 1999;Yang et al, 2001;Pantuwan et al, 2002;Kumar et al, 2008;Venuprasad et al, 2008;Wang et al, 2010). Multivariate indices including yield failure, RWC and WUE abilities, proline accumulation, P n reduction, F v /F m diminution, and pigment degradation data have been employed to classify members of water deficit tolerance, NSG19 and DD14.…”

Water shortage is a major abiotic stress for crop production worldwide, limiting the productivity of crop species, especially in dry-land agricultural areas. this investigation aimed to classify the water-deficit tolerance in mutant rice (Oryza sativa L. spp. indica) genotypes during the reproductive stage. Proline content in the flag leaf of mutant lines increased when plants were subjected to water deficit. relative water content (rWC) in the flag leaf of different mutant lines dropped in relation to water deficit stress. A decrease rWC was positively related to chlorophyll a degradation. Chlorophyll a , chlorophyll b , total chlorophyll , total carotenoids , maximum quantum yield of PSII , stomatal conductance , transpiration rate and water use efficiency in mutant lines grown under water deficit conditions declined in comparison to the well-watered, leading to a reduction in net-photosynthetic rate. In addition, when exposed to water deficit, panicle traits, including panicle length and fertile grains were dropped. the biochemical and physiological data were subjected to classify the water deficit tolerance. NSG19 (positive control) and DD14 were identified as water deficit tolerant, and AA11, AA12, AA16, bb13, bb16, CC12, CC15, EE12, FF15, FF17, G11 and Ir20 (negative control) as water deficit sensitive, using Ward's method.

“…10, No. 3;2018 agronomic parameters including days to flowing and maturity, number of tillers and panicles, 1000 GW and GY have been focused to be accounting for screening genotypes in rice breeding (Yang et al, 2001;Venuprasad et al, 2008& Wang et al, 2010. Results showed that different genotypes could be considered for acquiring required traits in rice crop breeding program.…”

Rice is second most consumed cereal after wheat and it is considered as staple food in Thailand and most of the ASEAN countries. Analyzing yield performance of upland rice genotypes under field conditions is a key step in rice crop breeding program for improved rice production and ensuring food security. The objective of this research was to conduct a yield trial to assess performance of sixteen Thai upland rice genotypes under field conditions for further breeding process. Data from field trial that was conducted in 2016 in field research area
