flowering will lead to delay in silking which will ultimately increase the anthesis to silking
interval and poor seed set (Bharathi et al., 2021). Hence selection of genotypes with shorter
ASI, smaller tassels and stay green traits will assist in breeding for water stress conditions.
Water stress during anthesis and silking reduces yield.
Conclusion
The knowledge on the association of yield and its components is of the great importance in
breeding. Hence low ASI and the cob characters viz., cob length, number of rows per cob,
number of kernels per row, shelling percentage can be given more importance in selection
criteria under rainfed conditions as they are contributing to yield.

Worldwide, agriculture consumes over 70% of fresh water resources used annually (Bacon,
2004). The rapid decline in fresh water resources, coupled with the demand for increased food
production to meet the population growth, poses a great challenge to agriculture. To maintain
or further increase agriculture output depends in part on the efficient management of water to
maximize water productivity, the concept of assessing agricultural output based on water
consumed rather than land area. Improvement in transpiration efficiency (TE), the inherent
water use efficiency, defined as biomass produced per unit water transpired through plants,
may be another viable approach to increase water productivity. Having higher TE could
