Abstract

Forty-two high yielding lowland and rice varieties were planted in two saline locations (Hagonoy and Binangonan), primarily to select varieties tolerant to high salinity.

In Hagonoy, salinity ranged from 0.467 to 0.608 percent, (moisture-free basis ). Out of 42 varieties planted, 15 died within 30 days after transplanting; 2 died before heading, and 10 died after flowering. Compared with the check,, only FK-135, FK-176 and Binangonan had more surviving hills; eight varieties had less chaffs; FB-121, AC 440 Dr 260, and Ac 2246 Mas had greater grain weight. Based on actual grain yield, salt tolerance may be ranked as follows: As 2246 Mas > Ac 440 Dr 260 > FK 176 > FK-135 > Dud Kuning > Binato.

In Binangonan, salinity ranged to 0.308 to 0.332 per cent (moisture-free basis). Compared with the check, only Ac 2246 Mas had more productive tillers; Milfor 6(2) alone had higher grain weight. None had less percentage of chaff. Based on actual grain yield salt tolerance may be ranked as follows: Peta > Tjere Mas > Ac 2246 Mas > FK-165 > Binato.

The varieties had better stand and were taller in Binangonan than the same varieties in Hagonoy. Seven varieties headed earlier in Hagonoy, five in Binangonan aand six at about the same period on both locations. Only Ac 2246 Mas had productive tillers at Hagonoy. Four varieties had about same percentage of chaff, and all varieties had greater weight and higher grain yield in Binangonan.
