In the present study, prominently evolved varieties of Indica rice (Oryza sativa L.) were studied and characterized. Effect of temperature and humidity on the grain yield and grain quality in different geographical areas of Northern India was studied. This would ensure the selection of rice varieties with respect to different geographical climatic regions. Seven varieties of rice were studied and characterized by the effect on their morpho-physiochemical characters in different climatic conditions of Uttar Pradesh and Haryana, India. All the seven varieties of rice except Sambha Sub-1 showed presence of fgr gene whose protein product are responsible for the peculiar fragrance of Basmati rice. This was also confirmed by the chemical assay for aroma. Morho-physiological characters of the crop namely; plant height, plant biomass, root biomass, leaf area, panicle length, spikelets per panicle, grain yield per plant and days of maturity were found to significantly correlate with each other with (P > 0.5). Biochemical studies performed showed the effect of temperature in different climatic conditions on total chlorophyll, chlorophyll a and chlorophyll b, total sugar and total protein. A significant correlation (p > 0.05) was observed between the higher and lower temperature and humidity respectively and different morpho-physiochemical characters. Four varieties of Basmati namely VB-21, VB-24, PB-1509, PB-1121 has been found to show higher morpho-physiochemical characters and grain yield per plant. VB-21 and VB-24 has been observed to resist the high temperature and low humidity in the region of Haryana as they have shown to produce higher grain yield, seed weight and grain quality.
