Guar is known for its drought hardiness and preferred for extraction of galactomannan gum. Its adaptability is proved in Mediterranean and sub-tropical environments. Information on its adaptability in semi-arid environments is limited. Hence, we evaluated six released varieties of guar (HG-365, HG-563, RGC-936, RGC-1002, RGC-1035 and RGC-1066) under rainfed conditions during kharif 2013 and 2014 with a view to identify agronomically and genetically superior ones. Among the varieties tested, RGC-936 produced significantly higher no. of branches and clusters thus seed yield (0.92 t ha-1). The seed yield was 87.8%, 44.0%, 35.7%, 26.5 and 24.5% higher than that of RGC-1066, RGC-1002, HG-563 and HG-365, respectively. Besides, higher gross and net returns (Rs. 46,508 and 31,758 ha-1) and B: C ratio ((3.15) were also accrued due to RGC-936 variety. Genetic analysis showed that plants with short height, more no. of branches, clusters and pod plant-1 are the important traits to be given priority to develop high yielding cultivars, as they influenced economic yield positively and significantly.
