Precise selection of superior Hevea genotypes from 2014 hand-pollinated progeny

Tropical Agricultural Research and Extension
The hybridization and selection in rubber (Hevea brasiliensis) aim to produce superior genotypes. The perennial nature of Hevea is the major limitation in rubber breeding. Early selection is crucial for strengthening and shortening the breeding program.

A decline in pollinator dependent vegetable crop productivity in India indicates pollination limitation and consequent agro-economic crises.

, 2011
Approximately 70% of the tropical crop species depend on pollinators for optimum yields (Roubik, 1995, Klein 2007). The economic value of such pollinated crops to India is $726 million and India is the world's second largest vegetable producer ...

The pollination requirement of the field bean (vicia faba)

, 1960
Many of the flowers on field bean plants fail to produce pods even when fully pollinated. When insect pollination is prevented pod production on the lowest inflorescences, which normally produce most pods, is reduced but a compensatory increase on the ...
