Most of the physical quality viz., hydration capacity, swelling capacity and swelling index are generally positively correlated among themselves and with 100-seed weight. Hydration capacity was positively correlated with hydration index, swelling caacity and cooking time. Seed volume, swelling capacity are important traits for the consumers, particularly when whole grains are consumed after soaking and cooking. The negative correlation between protein content and 100-seed weight; positive correlation between seed weight and sugars including RFOs indicate that bolder seed types are greater in causing flatulence while the smaller to medium size one had greater protein per cent Keywords: chickpea, correlation, physico-chemical traits, RFOs Introduction Chickpea (Cicer arietinum L.) is the world’s third most important food legume cultivated in Indian subcontinent, West Asia, the Mediterranean, North Africa and the America. India contributes the major share of about 65% global chickpea area and 68% global production. In India, it is grown in 9.21 million hectare area with a production and productivity of 5.3 million tons and 995 kg/ha, respectively (Kumar et al., 2017) [1] . Chickpea is widely consumed as a supplement in protein, making it a well-balanced human food. 100 seed weight is of primary importance and the most complex trait as it is dependent upon the interaction of growth, environment and genetic makeup of the plant. Genotypic and phenotypic correlations are of value to indicate the degree to which various quantitative and qualitative traits of the plant are associated with economic productivity. Correlation study thus provides information on correlate response of important plant traits and therefore leads to a directional model for yield response in terms of 100 seed weight. However, present study was initiated with the prime objective of observing the mutual relationships of different physico-chemical and quality traits and extent of their contribution to 100 seed weight of chickpea. The studies thus clearly envisage augmenting the relatively scarce information available on these characters which may be profitably exploited in future breeding programmes of chickpea improvement. Therefore, it is imperative to assess the genetic interrelationship of the traits with 100seed weight. Materials and methods Seventy chickpea genotypes were evaluated in randomized block design with three replications at Division of Genetics, Indian Agricultural Research Institute, New Delhi under normal sowing condition during winter season. For 100-seed weight, three random samples of 100-seeds each were weighed from each replication and the average weight was recorded. Three composite samples were drawn randomly from each plot for recording observations on different traits viz., sphericity, hydration capacity, hydration index, swelling capacity, swelling index, cooking time, sucrose, raffinose, stachyose, total sugars and protein content. Seed hydration capacity (g/seed) was calculated as percentage using the formula: HC = (W f – W 0 )/50 Where, W f is the weight of 50 seed soaked for 16 h and W 0 is the weight of 50 seed before
