Advantages;
Cross pollination leads to cross fertilization in plants . It brings about genetic recombination and introduced the variations in the offspring .
New and improved varieties of plants can be obtained by this technique due to the combination of characters of two different plants .
Plants obtained through cross-pollination are more resistance to disease and unfavourable condition .
It produced numbers seeds of better qualities and high viability .
It helps in the process of evolution .
New or improved varieties of plants are produce .
Disadvantages ;
Cross pollination is not a sure method as chance factor is always there .
It is a highly wasteful method as plants have to produce large no of pollen grains .
There is considerable wastage of pollen grains especially in wind pollinated flower .
It is less economical as the plants have to develop many devices to bring about this kind of pollination through various agencies .
It is less as the plants have to develop many devices to bring about this .
Some of the very good traits of the race are likely to be lose during recombination .
There are chances of the entry of some harmful and undesirable traits in the plants .Which may persist in the race for ever .
