Direct and Indirect Relationships among Lentil Chracters

Abstract: Abstract Correlation and path analysis were carried out for 24 lentil genotypes grown in three environments in Egypt (Sids research sta-tion in 1997/98 and 1998/99, and Giza research station in 1998/99 season). Season and location showed major effects on the per-formance of genotypes. Seed yield was positively and significantly correlated with pod and seed numbers, plant height and number of branches/plant, and negatively with flowering duration. Days to 50% flowering was significantly correlated with days to 100% flowering, 50 and 100% podding and days to maturity, indicating that selection for early flowering (50% flowering) is sufficient to identify the earliness in podding and maturity and no need to meas-ure other earliness traits to save time and cost. Path analvsis re- veiled that number of seeds/plant had the highest dirhest direct and in-direct effects on seed yield followed by pods/plant. But as yield component selection has unsuccessful in the past. Probably be- cause of yield component compensation, and measuring yield is much less time-consuming than counting/measuring components, selection for yield components is not justified.
