Marigold breeding is an active area of research. As for your question about selfing a single discless flower of marigold, it’s important to note that the ability to set viable seeds can depend on several factors, including the specific variety of marigold and the conditions under which the plant is grown
Generally, marigolds are capable of self-pollination. However, discless flowers may have reduced reproductive structures, which could potentially affect their ability to produce viable seeds. Bagging the flower can prevent cross-pollination and ensure that any seeds produced are the result of selfing.
If you’re planning to save seeds from marigolds, it’s recommended to wait until the blooms are spent, dry, and brown. You may still get viable seed from faded blossoms but the best marigold seed germination will likely come from the more mature ones.
Please note that these are general guidelines and the specifics can vary depending on the exact conditions of your study.
Thanks for your response...
I have another query related to this... I want to get a selfed seed from my plant that is discless...
As I review literature, I came to know that discless flowers only have ray floret s(ray florets have female reproductive Part only) ...
I bagged discless single flower and seed setting is done in those flowers...
How seed can be set in bagged flower if it has only gynoecoum in it??
disc less flowers are male petlous male sterile type as they lack male parts or male flowers. this type of sterility is liable to be broken and when you will bagg it certainly you will get seeds as i have experienced in in our heat tolerant African marigold cv Punjab gainda no 1 at Punjab agricultural university . however quantity of seed seeting will be less and of course in extreme summer it will will not set seed
