Abstract
A field experiment was conducted at the Main Agricultural Research Station, Dharwad during 2013-14. The
experiment consisted of five dates of sowing (D1, D2, D3, D4 and D5) and three genotypes (Annigeri-1, JG-11 and JG-14)
laid out with factorial RBD design replicated thrice. Among the temperature regimes, D3 temperature regime recorded
significantly highest plant height (45.9 cm), number of primary and secondary branches (9.6 and 12.0), days to physiological
maturity (97.5 days), growing degree days (GDD) for days to physiological maturity (1637), seed yield (29.88 q ha-1).
Among the genotypes, the genotype JG-11 recorded less plant height (38.8 cm) with optimum days to physiological
maturity (92.7 days) but primary and secondary branches (9.1 and 9.9), total dry matter (24.43 g plant-1), GDD (1563), HI
(53.19%) and yield recorded was significantly more (28.34 q ha-1). However, JG-14 recorded higher yield and yield
components than JG-11 and Annigeri-1 irrespective of dates of sowing. Therefore, JG-14 is considered to be the thermotolerant.
