Chlorosis mystery

"It has appeared in both early and late drillings. The real question is does it matter? Only the time will tell.

"Its a variety that has a lot to offer from the marketing point of view, and it would scandalous to see it rubbished before seeing the proof of the pudding through the combine." &#42
