Genetic variability, character association and path analysis for yield components in ginger (Zingiber officinale Rosc.)

Twentynine collections of ginger (Zingiber officinale) were studied for variability, character association and path analysis for yield and its 10 component characters. Wide range of variability was observed for most of the characters studied. Rhizome yield per plant was positively associated with plant height, number of fingers per plant ,weight of fingers and weight of primary rhizome. Plant analysis revealed that weight of fingers, width of fingers and leaf width were the strongest forces influencing yield. &nbsp

Multivariate analysis in chilli (Capsicum annum L.)

Thirty genotypes of chilli (Capsicum annum) were studied for genetic divergence for eight characters utilizing Mahalanobis D2 statistics. The genotypes were grouped into seven clusters. The genotype GP-65(A) was quite different and formed cluster VII. Variability in this material was limited and was mainly due to a few extreme types. The genotype(s) in clusters II, V and VII had the highest dry yield per plant and higher values for fruits per plant, fruit length and days to flower and could be utilized in breeding programmes. &nbsp
