Estimation of Heterosis for Yield and Its Attributes in Brassica rapa L.
Journal Title: Asian Research Journal of Agriculture - Year 2017, Vol 4, Issue 4
Abstract
Six parents of Brassica rapa (L) viz. SAU Sarisha-1, SAU Sarisha-2, SAU Sarisha-3, BARI Sarisha-6, BARI Sarisha-15, and Tori-7 were crossed in a half diallel fashion. The resultant fifteen hybrids along with six parents were evaluated in randomized complete block design with three replications with the aim of evaluating the performance of hybrids over their parents. The study was conducted at the Research field of Sher-e-Bangla Agricultural University, Bangladesh during Rabi 2010-2011. Results indicated that, all the parameters except 1000-seed weight and seed yield/plant were significantly differed among the parents indicated existing variation in the parents. The best performance was observed from the parents BARI Sarisha-15 and Tori-7. The growth as well as yield and yield attributes of all hybrids were also significantly differed. The highest seed yield was obtained from the hybrid CC6 (11.55 g/plant) followed by CC15 (9.75 g/plant) with a moderate days to flowering. The most heterotic hybrids for seed yield per plant were CC14, which produced significantly positive heterosis over mid-parent (35.99%) and better-parent (17.09%) in our study. However, the parent BARI Sarisha-6, BARI Sarisha-15, and Tori-7 can be used in any breeding program and the hybrids CC14 can be selected for further study towards a variety development.
