We wish to utilize such places for screening chickpea germplasm for late frost<br />

tolerance.<br />

Ensure that future cooperators in frost tolerance present air temperatures<br />

preceding the minimum temperature event to account for pre-conditoning<br />

effects!<br />

M.C. Saxena<br />

Your point is quite valid. In fact, in the paper these data have been qualitatively<br />

discussed.<br />

G.C. Ilawtin<br />

We have heard about the danger of late frost at the early flowering stage. I can<br />

envisage a situation where early frosts, say in November or early December,<br />

can also be important, i.e. plant growth may be occurring with high day time<br />

temperature but sudden drops in temperature at night and frosts could be very<br />

damagivg. Do we have any data on the probability of getting such early frosts?<br />

K.B. Singh<br />

We agree with your observations but unfortunately we do not have data on<br />

frost occurrence in early winter. Such information would be useful, not only<br />

from Syria but from th-oughout the region, where the crop is spring-sown with<br />

a possibility of introducing winter sowing.<br />

H. Harris<br />

The occurrence of frost in the early part of the season has not yet been<br />

examined, and we, therefore, have no information on the chance of frosts<br />

occurring during the s;eedling stage of growth of autumn-sown crops.<br />
