The identified heat tolerant donor Somaly crossed with high yielding varieties (short to medium duration) to generate the breeding material for heat tolerance S No. Cross combination 1 1 Somaly X MTU1010 Somaly X MTU1010 2 Somaly X Prasanna 3 Somaly X BPT 5204 4 Somaly X Vandhana
The donors grown in the field conditions crossed with the same set grown in heat tunnel and reciprocal crosses were also made to generate breeding material to study the pollen/stigma effect in the seed setting.
