I am searching for information (days until maturity) and PI numbers for the tobacco varieties that I am growing. I did a search for Nicotiana Yellow Twist Bud and got two PI numbers 552784 and 148270. Why are there two PI numbers and how do I know which one to use?
Furthermore, I clicked on Observations for accession for PI 552784 variety and I saw two Maturity values under Phenological descriptors (79 and 63). How do I know which value to use?
In other cases, when I searched for Nicotiana rustica, I got 174 hits. However, when I refined my search for rustica Aztec or rustica Mohawk or for any other rustica varieties, I get zero hits. These rustica varieties are commonly sold but why am I unable to get any information from GRIN in regards to their common variety name?
Again, the same thing happened when I searched for Nicotiana Zimmer Spanish – I received 3 hits and three different PI numbers (551284, 46907, 46906). Which one should I use? Under PI 551284, again I saw two Maturity values under Phenological descriptors (47 and 45). To the right of these numbers was displayed TC_AGRON 79TC_AGRONOMIC_LEX 79 and TC_AGRON 79TC_AGRONOMIC_OXF 79, respectively (under the Study/Environment heading). Which one of these should I use as a source of information? How should I interpret this data?
