Response of Segregating and Non Segregating Generations of Four Tomato Crosses to Environmental Variations for Physiological Attributes Related to Heat Tolerance
DOI:10.5958/2230-732X.2016.00004.8
Abstract:
Six generations obtained from each of the four tomato crosses viz. Cross-I (H7997 x CLN 1621 E), Cross- II (H7997 x BL 337), Cross - III (H7997 x Nagcarlan) and Cross- IV (H7997 x CLN 2366A) were evaluated over four environments. The analysis of variance exhibited significant differences among the genotypes for all the characters except for saturation deficit. The G x E interaction (linear) component was significant for all the characters except for relative stress injury. Pooled deviation was found to be significant for senescence index, membrane stability percentage, relative water content and saturation deficit. From stability analysis it was seen that hybrids H7997 x CLN 1621E, H7997 x Nagcarlan and H7997 x CLN2366A , F2 of cross H7997 x CLN 2366A together with B2 generation of cross H7997 x BL337 exhibited average stability for fruit yield per plant.
