Abstract
This work aimed at studying earliness, yield and photosynthetic parameters in some local and exotic rice resources. Twelve rice entries were used in the study including two from Bangladesh, one from Madagascar, three from Egypt, two from Korea and four from IRRI.  These genotypes were evaluated during 2020 and 2021 seasons in RCBD using four replications at the Faculty of Agriculture, Moshtohor Experiment Station. Significant differences were found among rice entries for all studied traits in the two growing seasons. The genotype GZ 10686-1-2-2-1 was the earliest among all studied entries, while genotype PR 78 was the shortest among all entries. Entry IRRI 142 had the highest significant value for chlorophyll content comparing to Giza 179, panicle length was highest with the genotype SAIBORO 9361. The genotype Korea 27 expressed the best mean values for panicle weight, weight of 100 grain and grain yield plant-1, while genotype IRRI 152 ranked the second best for grain yield plant-1. Genotype GZ 10848-1-2-2-1 was the best for number of tillers plant-1. Moreover, the genotype IRRI 152 exhibited the most desirable mean values for cuvette temp. and leaf diffusive, while genotype Korea 27 was the best for quantum sensor, stomatal conductance and Co2 assimilation rate in both seasons. For transpiration rate, the genotype AC 2882 expressed the best mean value, while Korea 47 gave the lowest value for this trait with significant difference from the variety Giza 179.
