HistorySeedling from Baldwin county Alabama. Comments This nut comes to us with a reputation of being a consistent bearer of mid-size nuts with excellent scab resistance. McMillan was planted in our orchards in 2002 and bore its first crop in 2005. So far, we have not observed scab on our trees in a sprayed orchard. This has been a high yielding precocious cultivar with yields approximately double those of 'Desirable'. 2009 was a heavy yielding year, with many limbs bending down, it will be interesting to see the follow up yield in 2010. Nut quality is only average, with a thick shell reducing percent kernel to about 50%, and kernel color being a little dark. Nut shucks are distinctive with a rough appearance. While the nut quality is not too exciting, the productiveness and scab resistance of this cultivar suggest it might be a good choice for low input plantings. Right now, I recommend it for trial in high scab pressure or low-spray situations. 'McMillan' is a type II (protogynous) cultivar. This cultivar was introduced by Auburn University and more information can be found on this selection HERE. |
'McMillan' nuts show no scab with fungicide sprays.
