Morpho-physiological Response of Selected Brassica Lines to Moisture Stress

Zakirullah, Zahoor A. Swati, Anwaar Ahmad and Raziuddin    

Abstract: Drought tolerance potential of five F10 brassica lines derived from interspecific crosses involving three genotypes of B. napus, two of B. juncea and one of B. carinata was assessed under green house conditions during crop season 1992-93. Relative leaf water contents (RLWC) were significantly altered by the three levels of moisture stress at flowering stage but genotypic differences were significant at the pod formation stage only. Leaf water potential (LWP) decreased with increasing stress and increased with age from flowering to pod stage. Under stress conditions plants generally took longer to complete 100% flowering, however, maturity was not significantly delayed. Brassica juncea was the earliest in reaching maturity followed by B. carinata and B. napus, respectively, while lines showed little differences. Leaf area decreased significantly with moisture stress, Whereas genotypic differences were significant for pod length, number of pods/main stock and number of secondary branches and non-significant for number of seed/pod and grain yield/plant. The Lines AY and WY derived from crosses between Altex X Yellow Raya and Westar x Yellow Raya, respectively were proved to be stress tolerant.
