Indian productivity is 490 kg\ha against 1200 kg for haryana,685 kg for Punjab and 669 kg\ha for Gujarat.Rajasthan productivity is 370 kg, whereas for Ganga nagar and Hanuman garh (807 & 870 kg, resp.), for Churu, Barmer,Bikaner (144-207 kg\ha ).</p></li><li><p>Improved varieties of guar suitable for different cropping regions, Rajasthan</p><p>Sl.

Serrata & C. senegalensis(High pods 45 days maturity, BLB resistance)[Wild sp.]No fertile hybrids</p></li><li><p> Stable, diversified and specific sources of guar viscosity may be identified.. Attempts may be made to develop guar varieties having different viscosity values ( low, medium ,high).</p><p>Specific growing inputs and environmental conditions may be specified in reference to gum quality..</p><p> Specific varieties with similar inputs may be grown in particular zone to have control over sustainability and traceability of guar gum and its quality.</p></li><li><p>Enhancing guar gum contentGuar gum content per se may be increased almost to 35.0% against existing values of 30-31 % for last many decades</p><p>A source (IC-116601) reported to have almost 34.83% gum content ,may be confirmed,if found stable be transferred into promising guar cultivars</p><p>Traditional and non-traditional approaches may be used in this context</p><p>could help increase gum yield even without increasing grain yield</p></li><li><p>Promising crop of guar in Virudgnagar ,T.
