Abstract

Thirty- five intervarietal crosses of gladiolus were tested separately in RBD, each with 3 replication in the ACRIP Floriculture, Department of Horticulture, RCA, Horticulture farm Udaipur from 2019-20. The objective of the study was to find the potentially of seed set in different crosses. Under intervarietal crosses, high capsule set per spike resulted in ‘H11 - ♀ GS-2 × ♂ Arka Amar (5.42), H12 - ♀ GS-2× ♂ Priscella (5.35), H1 - ♀ Anglia × ♂ Priscella (5.16), H13 - ♀ GS-2 × ♂ Punjab Beauty (5.14), H9 - ♀ Chandani× ♂ Punjab Beauty (5.10), H24- ♀ Pusa Gunjan × ♂ Arka Kesar (5.10) and H25 - ♀ Pusa Gunjan × ♂ Arka Pratham (5.00) per spike., but ‘H3 - ♀ Arka Amar × ♂ Arka Kesar (1.34), H18 - ♀ Punjab Beauty × ♂ GS-2 (1.40) and H33 - ♀ Pusa Subham× ♂ Nathan Red (1.50) produced the lowest capsule set per spike. ‘H13 - ♀ GS-2 × ♂ Punjab Beauty’ resulted the highest weight of capsule per spike (70.22 g) followed by ‘H11 - ♀ GS-2 × ♂ Arka Amar’ (61.75g). While the lowest in cross ‘H3 - ♀ Chandani × ♂ Arka Amar’ (13.91 g). ‘H25 ♀ Pusa Gunjan × ♂ Arka Pratham’ produced maximum number of seed per capsule (55.00) followed by ‘H11 - ♀ GS-2 × ♂ Arka Amar’ (54.00). While ‘H3 - ♀ Arka Amar × ♂ Arka Kesar’ the poor seed setting (9.00). The maximum number of seed set per spike in ‘H11 - ♀ GS-2 × ♂ Arka Amar’ (298.10) followed by the cross H24 -♀ Pusa Gunjan × ♂ Arka Kesar (239.70), whereas lowest number of seed set per spike in ‘H3 - ♀ Arka Amar × ♂ Arka Kesar’ (12.06). ‘H25 - ♀ Pusa Gunjan × ♂ Arka Pratham’ gave highest seed weight per capsule (2.10 g), while lowest in ‘H30 ♀ Pusa Kiran × ♂ Punjab Beauty (0.30)’. ‘H25 - ♀ Pusa Gunjan × ♂ Arka Pratham’ produced highest seed weight per spike (10.6 g) followed by ‘H11 - ♀ GS-2 × ♂ Arka Amar’ (8.8 g) and ‘H18 -♀ Punjab Beauty × ♂ GS-2’ produced lowest seed weight per spike (0.9 g)
