| dc.description.abstract | The investigation entitled “Genetic analysis of F1 hybrids in brinjal (Solanum melongena L.)” was undertaken at Main Garden, Department of Horticulture, Dr.Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Eleven genotypes (Aruna, Bhandara local, Wadsa local, Bhatai local, Manjarigota, Chandur local, Ruchira, Krishna Kathi, White Round, DBSR-52, White Brinjal) were crossed in line x tester mating design during kharif 2013. All parents and resultant crosses with standard check Phule Arjun (F1) were evaluated during Kharif and summer season of 2014-15 in Randamised Block Design with three replications. The observations were recorded on various growth,flowering,yield and quality aspects. The parents, Bhatai local, Aruna, Ruchira, White Brinjal, Wadsa local and Chandur local, while the crosses, Aruna x Ruchira, Bhatai local x Ruchira , Aruna x Chandur local, Wadsa local x Ruchira, Bhatai local x DBSR-52, Aruna x DBSR-52, Wadsa local x Chandur local and Wadsa local x DBSR-52 were found as best parents and hybrids respectively as evident from per se performance. The analysis of variance for treatments was highly significant for all the characters over both the seasons. The variance due to parents, females, males, female x male were significant for most of the characters. Whereas the variance due to interaction of parents x season, crosses x season and (parents Vs crosses) x season were also significant for most of the characters. The analysis for combining ability revealed the significant differences due to females, males, female x males, crosses, seasons, crosses x seasons, female x seasons, male x seasons and (females Vs males) x seasons, for most of the characters. The crosses, Wadsa local x Ruchira, Wadsa local x Chandur, Wadsa local x DBSR-52, Bhatai local x DBSR-52, Aruna x DBSR-52, Bhatai local x Ruchira, Aruna x Chandur local and Aruna x Ruchira were identified as potential crosses on the basis of average heterosis, heterobeltiosis and standard heterosis; which manifested heterotic effects for growth, earliness and quality traits. Among female parents, Bhatai local, Wadsa local, Aruna and among male parents, DBSR-52, Ruchira, Chandur local were identified as good combiner for growth, flowering(earliness), higher yield and quality characters. Six crosses viz., Bhandara local x Manjari Gota, Wadsa local x Chandur local, Wadsa local x White brinjal, Wadsa local x Ruchira, Aruna x Chandur local and Bhatai local x Ruchira exhibited significant sca effects for yield per plant and yield per hectare. The crosses viz., Wadsa local x Ruchira, Wadsa local x Chandur local, Bhatai local x Ruchira and Aruna x Chandur local were identified as promising hybrids on the basis of better per se performance, high standard heterosis in desirable direction, significant sca effects and both the parents involved in these crosses had good combining ability effects for yield per plant and most of the characters studied. Additive gene action was found to be predominant for all the characters in pooled mean, except plant spread where non-additive gene action was predominant. Analysis of genetic components of variation revealed that the importance of additive gene action operating in inheritance of yield and its important components. The information on nature and magnitude of genetic makeup of yield and its components thus obtained could be useful to the brinjal breeder in formulating an efficient breeding programme to achieve desired genetic improvement in this important vegetable crop. | |
