Stability analysis in bottle gourd Lagenaria siceraria Mol Standl

Abstract

The experiment entitled Stability analysis in bottle gourd [Lagenaria siceraria (Mol.) Standl.] was undertaken with the objectives (i) to estimate genetic variability in parents (ii) to estimate heterosis all possible parental combination (iii) combining ability variances and their effects, and gene action for yield and yield attributes, and (iv) to estimate stable genotypes and hybrids for planning of an appropriate strategy for development of high yielding bottle gourd genotypes/ hybrid as with stable as well as breeding procedure. The materials of experiment consisted of nine diverse parents (Rajendra Chamatkar (P1), Pusa Santushti (P2), Pusa Naveen (P3), Narendra Dharidar (P4), SBBG-23 (P5), SBBG-32 (P6), SBBG-31-1 (P7), SBBG-11 (P8) and HZP-RC-1 (P9) and their 36 F1s obtained by crossing in diallel fashion were conducted in randomized complete block design in three replications and three seasons viz., Early winter season (Eew, 3rd week of August-2013), Early summer season (Ees, 2nd week of November-2013) and Summer/ Main season (Es, 1st week of February-2014) having each experimental unit of single row with spacing of 4.0 m x 0.5 m at Vegetable Research Farm, Bihar Agricultural University, Sabour. newline
