Combining Ability for Yield and Fruit Quality in<i>Luffa</i>

Ridge gourd is popularly known as kalitori and also called as angled gourd, angled loofah, Chinese okra, silky gourd and ribbed gourd. Ridge gourd [Luffa acutangula (L).Roxb] or Ribbed gourd is an underexploited vegetable crop and it is an important Cucurbitaceous vegetable crop. It is grown as mixed crop in the river bed areas and as monocrop in the garden lands. It is widely grown in tropical and subtropical parts of the world. Ridge gourd belongs to genus Luffa of Cucurbitaceae and has a chromosome no. 2n=2x= 26. The genus derives its name from product "Loofah" which is used in bathing sponge, doormats, pillows and cleaning utensils. Ridge gourd, being predominantly monoecious, is a cross pollinated crop and provides ample scope for utilization of the hybrid vigour. During recent years, the exploitation of hybrid vigour and selection of parents on the basis of combining ability have expanded a new alley in crop improvement. These studies are generally used to assess the performance of lines in hybridization programme and to understand the gene action involved in different characters.

“…These crosses can be directly utilized for improvement of these char acter s thr ough the exploitation of heterosis or can be exploited for the development of better tr ansgressive segregants, since the parents Pusa Nutan, GARG-1, Jaipur Long and CO-1 involved in these crosses also exhibited high GCA. Similar r esults wer e r epor ted by Narasannavar et al (2014b), Niyaria and Bhalala (2001), Mole et al (2001), Sarkar et al (2015), Lodam et al (2009) and Tyagi et al (2010).…”

Line × Tester analysis involving three lines and four testers was carried out in ridge gourd [Luffa acutangula (Roxb.) L.]. Significant variation was noticed in the mean performance of the parents and hybrids for all the characters studied except for vine length and fruit girth. The results from GCA and SCA variance indicated the predominance of non-additive gene action for all the traits except fruit girth. Significant heterosis of 177.78% over standard check, Arka Sumeet for fruit weight per plant was expressed by the cross GARG-1 × CO-1. The best general combiners were GARG-1 and Pusa Nutan among the lines, and Jaipur long and CO-1 among testers. Best specific combining ability effects for fruit length and yield (t/ ha) were recorded by the crosses Pusa Nasdar × Arka Sumeet and GARG-1 × CO-1.

“…and Jaipuri Long x Swarna Manjari (63.82%) in E 4 exhibited highest heterobeltiosis and some other crosses like AHRG-1 x Swarna Uphar in E 2 , Swarna Uphar x Jaipuri Long in E 2 and E 3 , Jaipuri Long x Swarna Manjari, Swarna Uphar x Arka Sujath, Pusa Nasdar x Jaipuri Long, Pusa Nasdar x Swarna Manjari in E 4 exhibited significant positive heterobeltiosis for total fruit yield per vine. These results are conformity with the studies of Tyagi et al, (2010), Anand (2012), Reddy et al, (2013), Karmakar et al, (2014), Koppad et al, (2015) and Poshiya et al, (2015) who have reported a positive and significant standard heterosis for fruit length and total fruit yield found in ridge gourd.…”
