Seedling selection criteria
-
In cocoa, four yielding categories viz., [‘Low’ ( 3.0 kg)] were evaluated for standardization of seedling selection criteria at nursery stage. The results showed that the highest germination percentage, seedling height, girth, number of leaves, leaf area and seedling vigour were registered in high and very high yielding categories compared to other yielding categories.

In Kagzi lime the existing variability is less due to the problem of polyembryony which suppresses the zygotic seedlings. However, to some extent variation is seen in the seedling progeny with respect to morphological, physico–chemical parameters and also in productivity. In any crop, the improvement by selection method involves identification of prosperous types from a genetic stock or population. This can be from homogeneous population of heterozygous individuals in vegetatively propagated crops or from a population resulting from hybridization.
