Generation mean analysis for processing suitable seed traits of tomato (Solanum lycopersicum L.)

Abstract

Using generation mean analysis and gene actions for seed parameters of the 6 generations (P1, P2, F1, F2, B1 and B2) of the tomato cross IIHR 2847 X CLN3916C were estimated. The percent seed was lowest in line IIHR 2847 and highest in line CLN3916C. The hybrid IIHR 2847 X CLN3916C showed intermediate seed content. The experimental material was evaluated at the Division of Vegetable Crops, Indian Institute of Horticultural Research, Bengaluru. For characters and crosses with significant mean sum squares, gene effects were estimated. The scaling test was conducted using the standard errors, mean values and variances of several generations. The number of seeds, seed weight (g) and percent of seed content traits showed a duplicate type of epistasis, indicating that selection would not be successful for these traits because they were not fixable in earlier generations.
