<p>Characterization and Selection of 139 Potato Lines. One of the ways of increasing genetic variability in potato is interspecific hybridization to obtain new potato lines. This lines should then be characterized and used to obtain new breeding materials for potato breeding program. A total of 139 potato lines were planted at Cibodas-Lembang (1,300 m asl), from June 2004 to October 2004 without replication with population number of 5 plants per line. The result showed that (1) Generally the planted lines were round tuber shape (61.9%), yellow skin (98.6%), shallow eyes (71.2%), and light tuber weight per plant (89.2%); (2) 18 potato lines were selected as new breeding materials (13%).</p><p> </p><p><strong>Abstrak</strong></p><p>Salah satu cara untuk menciptakan keragaman genetik pada tanaman kentang adalah melalui hibridisasi antarspesies. Selanjutnya dilakukan karakterisasi galur yang dihasilkan. Diharapkan hasil karakterisasi dapat digunakan sebagai materi dalam perakitan varietas baru. Penanaman galur kentang hasil hibridisasi dilakukan di Cibodas, Lembang (1.300 m dpl), pada bulan Juni-Oktober 2004. Jumlah materi yang ditanam sebanyak 139 galur kentang, tanpa ulangan, dengan jumlah populasi sebanyak lima tanaman per galur. Hasil karakterisasi menunjukkan bahwa (1) secara umum galur yang ditanam mempunyai umbi berbentuk bulat (61,9%), berwarna kuning (98,6%), mata dangkal (71,2%), dan bobot umbi ringan (89,2%); (2) sebanyak 18 galur (13%) terpilih untuk digunakan sebagai materi pemuliaan lebih lanjut.</p>

Molecular markers reported to be linked to extreme resistance (ER) against Potato virus Y (PVY) were evaluated in potato germplasm. YES3-3A and YES3-3B, markers linked to Rysto, were detected in ‘Barbara’ and its three descendants that exhibit ER to PVY; RYSC3, a marker linked to Ryadg, was detected in breeding clones NY121 and NY123. Assessment of RYSC3 as a marker for selection for Ryadg-mediated ER validated its efficacy in identification of selections with ER to PVY.

In-row spacing studies have been conducted with `Beauregard!, `Hernandez' and some promising seedlings in the LSU Agricultural Center sweet potato breeding program. May, June and early July plantings are evaluated on 1 m rows with in-row spacings of 23, 30, 38, and 46 cm. With the variety `Beauregard' early May plantings (1-15th) yields of U.S. No.1 grade roots are higher at the 30 cm spacing. From mid-May to June 20th higher yields of No. 1's are produced at a 23 cm spacing. Higher yields are obtained in the late June-early July plantings at the 30 cm spacing. Highest yields overall are produced in late May-early June plantings with `Beauregard'. With the `Hernandez' variety the highest yield of U.S. No.1 grade roots have been produced at a 38 cm in-row spacing during all three planting seasons, with the highest yields overall being produced in the May plantings. Days to maturity are reduced in early `Hernandez' plantings. Results of limited in-row plant spacing with the seedling `LU7-59' are identical to the `Beauregard' variety.
