Hello,

It is also mentioned in the literature that a maximum of 25% success of crossing in Soybean are expected. The flowering of Soybean is to small and this leads to difficulties by the castration. So, a good fineness by Crossing and experiences could help you.

hello dear Bruno

thank you so much for your response.

usually my crosses fall down after 10 days or more while I can see all signs of successful crosses.

Use of plant growth regulators, sprayed on or near flowers and later.. may improve the set of fruits/seeds from interspecific pollination (Sastri, 1984).

I have applied gibberellins with success on soybeans (G. soja x G. max) and brassicas.

dear Alex

thank you so much

How much do you use of gibberelin????

I applied 10 mg/l for every day spraying.
