Abstract

The objective of this study was to evaluate the effect of water stress on morphological, seed yield and quality traits of sunflower cms analogues. The material comprised nine cms analogues having different cytoplasmic background namely CMS-XA (Unknown), E002-91, PKUZ-A, ARG-2A (H. argophyllus), ARG-3A (H. argophyllus), ARG-6A (H. argophyllus), DV-10A (H. debilis ssp vestitus), PHIR-27A (H. praecox ssp hirtus) and PRUN-29A (H. praecox ssp runyonii) with a common maintainer line (NC-41B). The material was grown during spring season 2011 and 2012 in randomized block design with three replications in a plot size of 4.5 m. × 0.6m. In water stress environment the irrigation was stopped after the anthesis was complete. The data was recorded on different morphological, seed yield and quality traits. The analysis of variance revealed highly significant differences for all the traits over the years. The cms analogues cms-XA (37.48g), E002-91(32.07g), ARG-3A (32.17g), PHIR-27A (34.03g) and PRUN-29A (30.42g) were observed to be significantly higher yielder than NC-41B (23.53g). This suggests that these sources may be exploited to develop water use efficient cms lines suitable for breeding hybrids for growing under water stress conditions. The results suggest these cms sources further use for developing water use efficient hybrids having different cytoplasmic background.
