  The present project was aimed to determine the correlation coefficients among different economically important traits using three varieties of Sorghum bicolor, and to ascertain the best combinations of characters to provide an ease to the breeders for improving those characters to improve biomass and yield. The sorghum varieties were PARC SS-1, PARC SS-2, and Pothwar 3-9 as control. The experiment was planted in July, 1998 at National Agricultural Research Centre (NARC), Islamabad in Randomized Complete Block Design (RCBD) with 3 replications. The plant observations were recorded from five earmarked plants in each plot and replication. The characters for observations were plant height, panicle length, 100-seed weight, number of grains/plant, days to 50% flowering, days to maturity, grain yield, stover yield and total dry matter (TDM). All traits were positively highly significantly (P<0.01) correlated with one another and yield. These findings indicate great scope for improvement in sorghum yield by improving the traits of 100-seed weight, panicle length, plant height and days to 50% flowering which are important yield components.

  To determine the correlation coefficients for different economically important traits using three warm-season forage legume species of cowpea (Vigna unguiculata (L.) Walp.), lablab bean (Lablab purpureus L.) and rice bean (Vigna umbellata Thunb.), the observations were recorded on plant height, number of branches/plant, number of pods/peduncle, number of pods/plant, number of seeds/pod, pod length, days to 50% flowering, 100-seed weight, days to maturity, grain yield, straw yield and biomass. Simple correlation was used to see the association among plant traits. The species were significantly (P 05) different for most of the parameters studied showing variability among the genotypes for those characters. A significant (P<0.05) positive correlation was observed for plant height with pod length and 100-seed weight, number of branches/plant with days to 50% flowering and days to maturity, number of pods/peduncle with number of pods/plant, pod length with seed size, number of seeds/pod with pod length, days to 50% flowering with days to maturity, grain yield with straw yield and TDM (total dry matter) and straw yield with TDM. It indicates that these positive associations may be exploited for any improvement work of the traits in warm-season forage legumes to improve their overall productivity and production.
