Abstract:
Evaluation of double hybrid (FC-1×FC-2) for the sources received from different places like SSPC, Vijayapura (Karnataka), SSPC, Udhampur (J&K) and DOS (J&K) during spring (2017 & 2018) for yield variation. Results revealed that yield obtained from SSPC (Vijayapura) is better (60.32 Kg/100 DFLs) when compared to SSPC, Udhampur (30.86 Kg/100 DFLs) and DOS (J&K) (35.88 Kg/100 DFLs) respectively during Spring (2017). The factors mainly observed for yield variation is that, quantity of seed received per 50 DFLs is less in two sources compared to SSPC (Vijayapura, KA) source and hatching percentage also it’s less than 90 compared to SSPC (Vijayapura, KA). Visual observation of larvae resulted plain in case of SSPC, Udhampur, plain and marked in DOS source and marked in SSPC source (Vijayapura, KA). During Spring (2018), the results observed that yield obtained from SSPC source (Vijayapura, KA) was recorded i.e. 92 Kg when compared to SSPC, Udhampur
i.e. 55 Kg and DOS, J&K
i.e. 45.50 Kg/100 DFLs respectively. The factors mainly observed for yield variation is that the quantity of seed, hatching percentage, True hybrid and disease incidences.
