Abstract:
Global warming is a challenge for rice production in the world. Thus, the rain fed rice areas are often affected with drought problems and consequently low yield per unit area. In experiment 1, five CSS lines and KDML105 were studied under water stress in hydroponic condition by using 10 % PEG 6000. The results showed that CSSLs performed better than KDML105 in most parameters measured particularly CSSL 1 which had high root to shoot ratio under drought stress due to high total length of nodal root and high number of nodal roots. In order to study the biomass partitioning under drought stress, KDML105 and four CSS lines carrying QTL segment on chromosomes 1, 3, 8 and 9 under hydroponic and soil systems with increasing concentration of PEG 6000 (5 %, 10 %, 15 %) was performed. The results showed that some CSSLs showed better performance than the KDML105 in all conditions. Root to shoot ratio significantly increased under drought stress in comparison with that under control condition. Biomass partitioning under hydroponic condition showed that the root dry weight increase when water stress increase because maximum root length and total length of nodal root increase but under soil condition the shoot dry weight increase because leaf dry weight and leaf area increased. Among the CSSLs and KDML105 tested CSSL3 and CSSL9 are tolerant lines and had the potential to perform better under drought conditions, whereas CSSL8 was susceptible under water stress conditions. The CSSL3 and CSSL9 had the smallest decrease in root dry weight and root to shoot ratio. Under soil system the result corresponds to hydroponic system but root dry weight and root to shoot ratio decreased under drought stress. The CSSL3 and CSSL9 had the smallest decrease in root dry weight and shoot dry weight.
