The new guar variety BR-2017 was evolved at Agricultural Research Station, Bahawalpur. The BR-2017 was evaluated/tested in Preliminary Guar Yield Trial (A-Trial), Regular Guar Yield Trial (B-Trial), Advance Guar Yield Trial (C-Trial), Zonal Guar Yield Trial and National Uniform Guar Yield Trial at different locations of Punjab in comparison with two check varieties BR-90 and BR-99.The BR-2017 produce high yield as compared to check varieties at all locations in different trials. The yield potential of BR-2017 was also assessed under drought stress conditions for areas experiencing water shortage. The performance of BR-2017 was good as compared to the check varieties under drought conditions which showed that this variety can be better adapted to the drought stress conditions and can produce better grain yield. The response of BR-2017 variety to insect pests and disease attack was studied and results showed tolerance to insect pests and diseases infestation compared with checked variety BR-99. The chemical analysis showed that the protein and gum contents of BR-2017 were comparatively better than the check variety BR99. The gum contents are about 35.20% which is about 2% higher than check variety BR-99 and similarly crude protein, meal and ash of BR-2017 was also greater than check variety. The BR-2017 retains better quality traits and gave best yield in drought and irrigated conditions and also resistant/tolerant to all diseases and insect pests. This variety has the capability to replace the other previous guar varieties.
