I've been working with genotypes from Texas and India and in literature I found contradictory information about their stay-green characters, especially for the genotype R16. Moreover, S35, E36-1 and ICSV273 are said to be post-flowering drought resistant, but E36-1 expresses the stay-green trait only under drought conditions. Tx7000 is pre-flowering resistant and no stay-green type. I found no information about IS7324, it's an old landrace.
You must have read work by Dr. Andrew Borrell who has been working on Staygreen for sometime now. You may want to address your question to him at: [email protected]
Hi Jorita,
Stay-green is not a simple trait and is highly context dependent which makes your question a challenge to answer easily. It is not easy for example to compare the stay-green character in different sources as it is confounded by issues like height flowering time and grain number. Both Andy Borrell ([email protected]) and I have been working on the trait for some time and would be happy help you with your questions by email ([email protected])
Cheers
David
