Chickpea is a cool season food legume and incurs heavy yield losses when exposed to high temperatures at reproductive stage. Heat stress at reproductive stage is increasingly becoming a serious constraint to chickpea production because of large shift in chickpea area from the cooler, long season environments to warm, short-season environments, increase in area under late sown conditions, and reduction in winter period and expected increase in temperatures due to climate change. This projects aims at understanding mechanisms and genetics of heat tolerance in chickpea and develop breeding lines with improved heat tolerance. Heat tolerant cultivars will be more resilient to the impacts of climate change, allow flexibility in sowing dates and enhance opportunities for expanding chickpea area in new niches and cropping systems, such as rice-fallows.This project is aimed at (1) developing techniques for effective screening of chickpea genotypes for heat tolerance at reproductive stage, (2) identifying chickpea genotypes with reproductive stage heat tolerance, (2) understanding mechanisms and genetics of heat tolerance, (3) identifying molecular markers for gene(s) controlling heat tolerance, (4) introgressing heat tolerance in selected cultivars/elite breeding lines, and (5) evaluating selected heat tolerant lines at farmers fields. The breeding material developed in this project will be further evaluated by the partner institutes and others, leading to development of heat tolerant cultivars

Outputs expected from the project are, techniques standardized for screening chickpea genotypes for reproductive stage heat tolerance, a set of heat tolerant chickpea genotypes identified and selected lines evaluated at farmers’ fields, genetics of heat tolerance worked out and molecular markers identified for heat tolerance gene(s), and breeding material developed by introgressing heat tolerance in locally adopted cultivars.Activities include, standardize techniques for large scale screening of chickpea germplasm for heat stress at reproductive stage, screen a set of genotypes (germplasm, cultivars and breeding lines) at multiple locations for their ability to flower and set pods at high temperatures, study reproductive behavior of heat tolerant and heat sensitive genotypes under normal temperatures and under heat stress, study genetics of heat tolerance, develop RILs for mapping heat tolerance gene(s), identify molecular markers for heat tolerance gene(s) through association mapping and linkage mapping, develop heat tolerant breeding lines with suitable agronomic background, and evaluate selected heat tolerant lines at farmers’ fields.  Expansion of project to involve marker-assisted breeding for heat tolerance planned, if able to identify markers for heat tolerance under the current project, and studies on comparative genomics of legumes for heat tolerance.

    It is with great interest I came across your project on Improving Heat Tolerance in Chickpea for Mitigating Impacts of Climate Change on its productivity on Google search. Let me introduce myself, I am Dr Neeraj Kumar working as a scientist (Pulse physiologist) here in CCS HAU, Hisar, Haryana, India.

    Will you please let me know about the techniques you are using for effective screening of chickpea genotypes for heat tolerance at reproductive stage? I am also conducting similar trials for Low and High temperature screening for chickpea under field conditions here in pulses section CCS HAU, Hisar.

    Looking forward to your valuable suggestions

    With best regards

      We sow the crop late in the season (Feburary at Patancheru) as to coincide high temperatures with reproductive stage. We use pod set as the major criterion for ascertaining heat tolerance. You can find further details in the following publication:

  2. Dear Sir
    Under the current scenario, all the members of the project are much appreciated. My best wishes for the successfully complition of the project.

    let me introduce my self, i Mr. Bhasker, P, Ph.D Scholar, in CCSHAU,Hiasr, iam doing Doctoral research work on “Physiological and Biochemical changes in Chickpea under High Temperature conditions” let me know the about the trails which you are using.
    I am waiting for your valuable information.

  4. This is Dr Madan Pal,IARI, New Delhi and interested to know your approach for exposure to high tempearture stress under natual environment.

    • Pooran Gaur says:

      We are screening for heat tolerance by sowing the crop late in the season (Feb) as to coincide reproductive stage with high temperatures. Pod setting is the main trait being considered is assessing heat tolerance.

  5. Dr. A. K.Srivastava says:

    In simulation study it is reported and observed that Chickpea yield may not be affected by maximum temp. of 38 degree c in flowering/reproductive stage. Is this this limit is extended by screening experiment?

  6. Gurdev Chand says:

    let me introduce myself I Gurdev Chand PhD scholar Plant Physiology CCS HAU Hisar. Sir, I want to make research on chickpea which type of work will be the burning topic for me on the Physiological basis.
    Give me any topic related to Plant/Crop Physiological basis.
    Thanking you

    • Pooran Gaur says:

      Drought, salinity, high and low temperatures are the major abiotic stresses for chickpea. The scientists in your Department would be in a better position to suggest you a research topic on one or more of these stresses based on the priorities of the University and materials and facilities available in the department.
