Abstract:

Fruit crops, mostly perennial, are highly heterozygous with a complex genetic nature and several cross-breeding barriers. Among the various evolutionary mechanisms of floral behavior reported in fruit crops, dichogamy is one of the most important mechanisms with the most prevalent also. Dichogamy refers to the maturation of sex organs at different times in plants. It is mainly divided into two main types; protoandry and protogyny. However, various other classifications have also been suggested by the scientists in flowering plants which further elaborated the mechanism. These were based on the basis of floral elements (intrafloral and interfloral), degree of stamen and pistil separation (complete and incomplete), degree of plant synchronization (asynchronous, hemisynchronous and synchronous) and by the time interval between stamen and pistil emergence. some special types viz., duodichogamy, heterodichogamy and PDSD were also exhibited by different fruit crops. Dichogamy promotes outcrossing even in hermaphrodite species which controls genetic transmission within and among the population. The present paper reviewed the types and characteristics of dichogamy observed in various fruit crops. The comprehensive knowledge of it is mandatory for good fruit setting with quality and higher yield along with further improvement in fruit species.
