Abstract:
Quality and quantity of crops are adversely affected by both biotic and abiotic stresses. Abiotic stresses can even lead to complete loss of the standing crop and one among the major constraints is lodging. As far as cereals are concerned lodging is a major problem and climatic conditions can even enhance the chances for lodging. The biochemical components in the plant like starch, cellulose and lignin can provide resistance to lodging. Variability if lacking for the particular characters can be induced by mutagenesis thereby increasing the chance of selection for resistant types. The present study was conducted with the objective of assessing the correlation of biochemical components and lodging resistance in rice varieties after mutagenesis. Positive correlation was noticed for starch and cellulose content in the stem and it shows that stem rigidity is associated with these biochemical components in the stem.
