Heterosis for fruit yield and its contributing traits in Okra (Abelmoschus esculentus (L.) Moench)


Author(s): Monika Punia, DK Garg and Anita Burdak

Abstract: The Okra (Abelmoschus esculentus (L.) Moench) cultivars were sown at Horticulture Nursery in university campus, SKRAU, Bikaner during Kharif 2014. All the recommended general package of practices was followed for raising the good crop. Nine parents (6 lines and 3 testers) and their 18 F1S were grown in a randomized block design (RBD) with three replications. One check variety, Komal 10 was also used as standard check. Crosses among the nine genotypes were made in line x tester mating design at Horticulture Nursery in university campus, SKRAU, Bikaner during Zaid 2014. Out of 18 crosse combinations, some crosses showed the significant heterosis over better parent and standard check. Early and extra early genotypes seem to be a priority, therefore negative heterosis is desirable for days to 50 % flowering and days to maturity. The cross Kashi Pragati x Arka Anamika showed heterobeltiosis for nine characters viz., days to 50% floweing, days to maturity, plant height, number of fruits per plant, fruit length, fruit weight, biological yield and fruit yield per plant. The crosses which showed heterobeltiosis for more than six characters were Hisar Naveen x Arka Anamika, Varsha Uphar x Arka Anamika and Kashi Kranti x Arka Anamika.The cross Varsha Uphar x Arka Anamika showed standard heterosis for all the characters, while crosses like Hisar Naveen x Arka Anamika, Kashi Kranti x Hisar Unnat, Kashi Kranti x Arka Anamika and Kashi Pragati x Arka Anamika exhibited standard heterosis for more than six characters. Therefore, these crosses have good potential for heterosis breeding.
