Two words - Roundup Ready - captured the spotlight again in the soybean breeding arena for new varieties for 1999.

Whether deserved or not, that's where the big growth occurred.

Consider the University of Wisconsin variety trials as one example. Out of 256 new varieties tested in 1998, 125 were Roundup Ready (RR). That compares to a handful the first year, according to Ed Oplinger, extension soybean specialist.

Most scientists agree that the RR and other herbicide-tolerant crop technologies are great.

But, they warn, the RR or any other herbicide-tolerant gene should not be the starting point when choosing a variety.

Some growers have shot themselves in the foot big time by rushing to get the technology and then taking a yield hit because the gene was not put in the very latest, highest-yielding lines.

Or they passed up the chance to protect against soybean cyst nematodes or some yield-reducing disease they had in their fields just to get RR or some other herbicide-tolerant technology.

Breeders' advice: First choose varieties adapted to your area, then varieties with the correct disease-protection package for your situation, strong emergence, standability, etc. - and finally yield results based on multiyear, multilocation tests.

Soybean Digest's exclusive national new-variety roundup each year describes the most important characteristics of each variety covered to help you pick those that best fit your individual situations. But if a trait that is important to you is not mentioned, it's because the variety doesn't have that certain disease or nematode resistance, for example. If it did, it would be mentioned - count on it.

Keep in mind that we have limited each company and university to a maximum of four entries due to space limitations. Some companies may offer up to 15 or 20 or more new varieties for 1999. So check them out, too, because in some cases, they may fit your requirements better than those mentioned.

For the ninth year, protein and oil composition percentages are given for most varieties. All are compared on a 13% moisture basis, rather than a dry matter basis.

The percentages are compared against the American Soybean Association's and United Soybean Board's annual survey by state and region. Disregard small differences, such as a few tenths of a percentage point, because these figures are relative.

Here's a listing of the pureline variety choices (no blends included) by relative maturity group. The up-to-date listing comes from soybean breeders or agronomists at USDA-ARS, universities and private companies - not their public relations or marketing people. It comes from companies or universities with their own breeding programs or ones that are significant players in the soybean seed industry.

:>TI Roundup Ready Trait Dominates New Varieties (Southern Version)

Two words - Roundup Ready - captured the spotlight again in the soybean breeding arena for new varieties for 1999.

Whether deserved or not, that's where the big growth occurred.

Consider the University of Wisconsin variety trials as one example. Out of 256 new varieties tested in 1998, 125 were Roundup Ready (RR). That compares to a handful the first year, according to Ed Oplinger, extension soybean specialist.

Most scientists agree that the RR and other herbicide-tolerant crop technologies are great.

But, they warn, the RR or any other herbicide-tolerant gene should not be the starting point when choosing a variety.

Some growers have shot themselves in the foot big time by rushing to get the technology and then taking a yield hit because the gene was not put in the very latest, highest-yielding lines.

Or they passed up the chance to protect against soybean cyst nematodes or some yield-reducing disease they had in their fields just to get RR or some other herbicide-tolerant technology.

Breeders' advice: First choose varieties adapted to your area, then varieties with the correct disease-protection package for your situation, strong emergence, standability, etc. - and finally yield results based on multiyear, multilocation tests.

Soybean Digest's exclusive national new-variety roundup each year describes the most important characteristics of each variety covered to help you pick those that best fit your individual situations. But if a trait that is important to you isn't mentioned, it's because the variety doesn't have that certain disease or nematode resistance, for example. If it did, it would be mentioned - count on it.

Keep in mind that we have limited each company and university to a maximum of four entries due to space limitations. Some companies may offer up to 15 or 20 or more new varieties for 1999. So check them out, too, because in some cases, they may fit your requirements better than those mentioned.

For the ninth year, protein and oil composition percentages are given for most varieties. All are compared on a 13% moisture basis, rather than a dry matter basis.

The percentages are compared against the American Soybean Association's and United Soybean Board's annual survey by state and region. Disregard small differences, such as a few tenths of a percentage point, because these figures are relative.

Here's a listing of the pureline variety choices (no blends included) by relative maturity group. The up-to-date listing comes from soybean breeders or agronomists at USDA-ARS, universities and private companies - not their public relations or marketing people. It comes from companies or universities with their own breeding programs or ones that are significant players in the soybean seed industry.
