  • the present invention relates -to;a new and distinct variety of peach' tree ofthe light-fleshed, greenish-yellow skinned, freestone fruit type and more particularly to such a peach tree characterized by the production of'seeds having special advantages as seedling rootstock.
  • An object of 'the present invention was, therefore, to
  • Another object was-to provide a peach tree which is a regular and heavier bearer of small freestone fruits which are easy to gather and fromwhich the seeds are easily extracted.
  • Another object was to provide a peach tree capable of producing progeny which have vigorous root systems and are vigorous in growing-habits. 1 v 1 Another object was to provide a peach tree which is remarkably uniformly resistant to nematodes crown gall disease, damage incident to excessive irrigation,.and resistant and tolerant of other diseases, adverse environ-.
  • the instant variety of peach tree resulted from a planned and deliberately followed-procedure directed to the attainment of improved peach tree seedlings.
  • a nu1n ber of open pollinated F-l seed of a variety known as Plant Pat. 1,941 4' 99 9 of the seedling trees was markedly superior in nematode and disease resistance and possessed desired vigorous growth. Seeds from this single selected treewere then grown in a nursery row. When ready for budding, the scions were taken from the original parent tree for the purpose of creating a mother orchard of identical origin and entirely free of disease. This asexual reproduction of the peach tree occurred at Collinso Fortuna, near the city of McFarland, county of Kern, State of California. f
  • the resultant budded trees were carefullyexamined and found consistently to possess the characteristicsof the I selected tree.
  • the drawing shows specimens of leaves growing on first and second year branches, characteristic fruit,'a peach cut transversely of the suture plane and open for inspection of both resultant halves, a peach cut on suture plane'and likewise opened for inspection, and characteristic stones,
  • the most striking characteristics of the new peach tree is its transmission to its seed progeny substantially uniform characteristics of growth, desirable budding traits,
  • the seeds of the subject variety and v the 8-37 were planted in uniformly spaced relation while the seeds of the Lovell were planted more thickly and then thinned to the same spaced relation. This is in accordance with normal nursery practice because of the low rate of germination of the Lovell seeds.
  • the seeds were planted at the same depth, in the same type of soil, and grown under as precisely the same growing conditions as possible. By May 16, the seedlings had reached nearly budding size. Care was taken to select as nearly typical sections of the rows of the three varieties as possible, and
  • Seeds of the subject variety, Lovell and 8-37 were sown in each of the tanks in individual rows, germinated, and grown for the same period under precisely identical cultural conditions. The seedlings were dug at the same time and their roots carefully inspected and graded with respect to nematode infestation in accordance with the following scale. 5
