Pant Brinjal Hybrid-1" wa carried out at Vegetable Research Centre of the G. B. P. U. A. & T. , Pantnagar during autumn-winter season of 2003-04. The material for the study consisted of PBR-129 (female) and PBR 225 (male), parental lines of Pant Brinjal Hybrid-1. Both the parental lines were planted in Randomized Block Design with four replications in three planting ratios. The seeds were extracted through two methods viz., Manual and mechanical methods of seed extraction. The data was subjected to appropriate statistical analysis. The di f ferences for most of the characters were found non - signi ficant. Maximum number of crossed fruits, number and weight of seeds per fruit and hybrid seed yield was recorded in the planting ratio of 1: 5. The seed test weight ranged from 5.61 to 5.77 g. The Fi seed yield of 22.0 kg/ha was recorded in manual seed extraction method. The seed germination (75 %) was better in manual method of seed extraction. In most of the c ases the ef fe ct of method of seed ext rac t ion and i ts interactions with planting ratio were found non-significant indicating that there was no. effect of method of extraction on yield and quality of hybrid seed. Further, the finding of present investigation indicate that for raising the F1 hybrids seed of brinjal the emasculation and pollination should be done in the month of October and November under Tarai region of Uttaranchal.ennullThesis
