Abstract
An investigation was carried out to find the effect of spacingand planting ratio on seed yield and quality parameters inchilli at Main Vegetable Research Station, Anand andDepartment of Seed Science and Technology, BACA, AAU,Anand during Kharif-Rabi season of the year 2019-20. Plantspacing 90 × 60 cm (S2) recorded significantly highest seedyield per plant (23.98 g), number of fruits per plant (103.13),germination per cent (95.11 %), seedling root length (4.71cm), seedling shoot length (4.54 cm), seedling length (9.24cm), seedling fresh weight (381.3 mg), seedling dry weight(20.53 mg), seedling vigour index I (879.90) and seedlingvigour index II (1954.4). Irrespective of plant spacing, amongthe three planting ratios, planting ratio 2:1 (P2) recordedsignificantly higher number of fruits per plant (115.58), weightof fruit (1.018 g), fruit length (9.32 cm) and fruit girth (3.97cm), number of seeds per fruit (42.16), 1000 seed weight(5.76 g), seed surface area (8.74 sq. mm), seed yield per plant(27.54 g), germination (94.67%), seedling root length (4.61cm), seedling shoot length (4.45 cm) and seedling length(9.06 cm), seedling fresh weight (384.1 mg), seedling dryweight (20.81 mg), seedling vigour index I (858.92) andseedling vigour index II (1971.80). However, significantlyhigher fruit to seed ratio (4.77) was found in 3:1 plantingratio (P3) in seed parent of chilli hybrid
