Our plant-breeding efforts have been directed at creating salt-tolerant seed varieties capable of surviving very high salinity, while at the same time producing very high yields.
A high yielding, high quality, multi-leaf, dormant variety of alfalfa with good resistance to Phytophthora Root Rot, Fusarium Wilt, Bacterial Wilt, Pea Aphid, Spotted Alfalfa Aphid, Stem Nematode, Verticillium Wilt, Aphanomyces Root Rot, Northern Root Knot Nematode and Anthracnose.
Adaptation
SW 435 is adapted to the winter-hardy intermountain west and to irrigated areas of the Sacramento Valley and Northern San Joaquin Valley of California, with fall dormancy rating of 4.
Disease, insect and nematode resistance
SW 435 is highly resistant to Phytophthora Root Rot, Fusarium Wilt, Bacterial Wilt, Pea Aphid, Stem Nematode, Anthracnose and Aphanomyces Root Rot. It is resistant to Spotted Alfalfa Aphid, Northern Root Knot Nematode and Verticillium Wilt. Reaction to Blue Alfalfa Aphid has not been tested.
Uses
The milk production per acre for this variety is quite high when compared to other varieties in a trial in Nampa, Idaho. In five forage yield trials in Idaho and Washington, SW 435 has produced higher yields than other major varieties and has averaged 5% above means of all five trials. SW 435 has high multi-foliolate leaf expression (78%). This is a high quality forage producer.
Summary
SW 435 combines high forage quality, fast recovery after cutting, and excellent forage yield potential with excellent
winter-hardiness. Multiple pest resistance is excellent. This variety has performed well over a wide range of environments and is adapted to areas where FD 4 or 5 varieties are planted.
