Description:
Pigeonpea (Cajanus cajan) is a pulse crop capable of alleviating malnutrition, improving soil health and livelihood of small-holder farmers of Asia and Africa. This climate-resilient grain legume plays an important role in the semi-arid topics inhabited by over 2 billion people where malnutrition in women and children is a serious concern. Therefore, it becomes imperative to increase its yield that has remained stagnant for over last 5-6 decades despite varietal development. In this regards, a three-line hybrid breeding system in pigeonpea has been utilized to escalate its productivity with 30-40% on-farm yield advantage. Presently, a two-line hybrid technology is being explored to simplify the existing hybrid system for rapid, inexpensive and high-quality hybrid seed production in pigeonpea. Our present study identified and characterized a thermo-sensitive genic male sterile (TGMS) line which would form the core component of a possible two-line hybrid system. Furthermore, precise phenotyping together with cytological analysis and ‘multi-omics’ approach have enabled us to outline a molecular mechanism that underpin fertility transition responses for a process-oriented two-line hybrid breeding framework for pigeonpea.
