To achieve this, cotton (Gossypium hirsutum L.) breeding programs must develop cultivars that overcome the negative relationship between agronomic performance and fiber quality. Since 1935, the USDA‐ARS Pee Dee germplasm enhancement program has priori ...

Abstract:
... Diverse citrus cultivars maintained clonally within gene banks serve as valuable resources for research and breeding programs worldwide. These critical collections are kept as trees within field, screenhouse, or greenhouse collections. Ex situ collections are at risk of being lost due to unforeseen environmental or biological disasters. Cryopreservation provides a secure method to back-up these im ...

A series of studies determined that increased amounts of mesos components (CaCl2, MgSO4, KH2PO4) and changes in the nitrogen (N) were required for producing high quality shoots for five pear genotypes. Many species required unique combinations of N ions (NO3- a ...

Apple production has high costs for land, labor and inputs, and orchards are a long-term commitment. Production is dominated by only a few apple scion and rootstock cultivars, which increases its susceptibility to dynamic external threats. Apple crop wild relatives, including progenitor species Malus s ...
