Abstract:
The experiment were carried out in two years with aims to determine gene action involving 9 parental lines viz., NDSG-1, NDSG-20, NDSG-22, NDSG-24, NDSG-26, NDSG-28, NDSG-30, NDSG-32 and Pusa Chikni of sponge gourd and their 36 F1 hybrids at MES, Vegetable Science, N.D.U.A.&T., Kumarganj, Faizabad (U.P.) during crop seasons of summer (Zaid) 2014 and 2015. The experiments were laid out in RBD with three replications having each experimental unit of single row with spacing of 3 m x 0.5 m. Heritability is a useful measure for considering the ratio of genetic variance to the total variance and is generally represented in percentage. This is an index of transmissibility of characters from the parents to their off springs and is a measure of genetic relationship between parents and progeny, hence changing the characteristics of the population through selection can be predicted only from knowledge of the degree of correspondence between phenotypic and breeding values.
