Estimation of genetic components of variation and heterosis studies in bitter gourd for horticultural traits

Exploiting Gynoecious Line for Earliness and Yield Traits in Bitter Gourd (Momoredica charantia L.)

“…However, the utilisation of gynoecy is economical and easier for exploiting hybrid vigour in many cucurbits including bitter gourd (Behera, 2004) that have high male: female sex ratio. Using gynoecious line as one parent in hybrid breeding, it showed positive impact in terms of yield and earliness (Dey et al, 2010;Gangadhara Rao et al, 2018). Keeping in view the above facts, the present investigation was carried out to examine the extent of heterosis in 28 F 1 hybrids by using eight diverse parents.…”

Biochemical Characteristics of Bitter Gourd (Momordica charantia L.) in Southern India

“…Bitter gourd contains a reasonable amount of different nutrients such as proteins, carbohydrates, fats, minerals and vitamins A, B 2 , and C etc. Raja et al (2007) reported very high amount of vitamin C (95 mg-100 g -1 ) and protein (930 mg-100 g -1 ) in some Indian bitter gourd varieties. Fruits of bitter gourd are widely consumed as In this present investigation, F 4 progenies of three cross combinations of bitter gourd namely, P 1 × P 4 (MC105 × Pant karela-2), P 2 × P 4 (TCR471 × Pant karela-2), P 3 × P 6 (BBGS-09-1 × Arka Harit) and their respective parents P 1 (MC105), P 2 (TCR471), P 3 (BBGS-09-1), P 4 (Pant karela-2), and P 5 (Arka Harit) were used to analyze the biochemical properties such as total soluble solids, protein content, ascorbic acid content, iron content, momordicine content and total chlorophyll content.…”

Standardized Protocol for In Situ and In Vitro Maintenance of Newly Developed Parthenocarpic Gynoecious Cucumber Inbred

“…Though monoecious is the predominant sex form in cucumber, but gynoecious sex form has been exploited for F1 hybrids production. Gynoecious line as one parent in hybrid breeding has positive impact on yield and earliness [4] but, if gynoecious trait is associated with parthenocarpy, then yield is even higher than the gynoecious hybrids. Parthenocarpy is one such trait in cucumber that is highly preferred by consumers and has a great demand in market.…”
