- Mungbean (Vigna radiata) is a legume crop with a short life-cycle and the ability to self-pollinate, which make it easy to breed and to cultivate. Mungbean is adapted to tropical environment condition and it is susceptible to be affected by the flexible environment. So the cultivation area tends to be concentrated in developing countries that are more inflexible than other countries. Mungbean also has the characteristic of non-synchronous maturity caused by indeterminate flowers, which requires several times of harvest.
The objective of this study was to find the association of inflorescence architecture traits with synchrony by observing the inflorescence architecture in the mungbean. Mungbean has a compound raceme inflorescence architecture that has both a main (primary) branch and secondary branches that can produce flowers. On the other hand, there was a unique genotype named Binh khe D.X. that has only a single main branch that produces flowers in a simple raceme inflorescence architecture. Generally, we observed non-synchronous lines made new peduncles and branches during multiple harvesting period. These changes were shown to influence the synchronous pod maturity and this discovery could be used to aid the development in future mungbean breeding
