Four lines and six hybrids from crosses amongst them were studied. The line 33-16 had the lowest rate of nitrate uptake in the roots and the highest nitrate reductase activity in the leaves; the reverse was true of B14. All the hybrids showed heterosis for nitrate transport; heterosis was greatest in 33-16 X L1058. Heterosis for nitrate reductase activity was appreciable only in 33-16 X WF9.

Abstract

Four lines and six hybrids from crosses amongst them were studied. The line 33-16 had the lowest rate of nitrate uptake in the roots and the highest nitrate reductase activity in the leaves; the reverse was true of B14. All the hybrids showed heterosis for nitrate transport; heterosis was greatest in 33-16 X L1058. Heterosis for nitrate reductase activity was appreciable only in 33-16 X WF9.
