Variation in flowering and fruit set among indigenous mango varieties from Malda and Murshidabad conserved as Field Gene Bank in Gurudas College, Kolkata, India
Variation in flowering and fruit set among indigenous mango varieties
The flowering phenomenon in mango is a complex one. Normally, it crops heavily in one year (on year) and bears less or no crop the following year (off year). Again, it yields heavily the next year. These alternate bearer fruit cultivars present a serious economic problem to fruit growers in West Bengal. Fruit set in Mango is a varietal character, depending upon several factors such as time of flowering, sex ratio, efficient cross-pollination and intensity of flower drop. Varieties differ from one another in these respects and this leads to varying fruit set in different varieties. Understanding the cellular and molecular mechanisms involved in regular and irregular bearing fruit varieties will assist in the development of flowering, identification of regulatory regions and factors implicated for regularity in bearing in mango. Transcriptomic data could be utilized for the synthesis of SSR and SNPs markers. Varieties both alternate and regular bearing need to be identified before the transcription profiling. In this investigation the variation among the 25 mango varieties conserved as field gene bank in the college campus of Gurudas College was assessed.
