| The present investigation was carried out to study the direction and magnitude of heterosis in twenty-four hybrids for yield contributing head traits in cabbage (Brassica oleracea var. capitata L.). A field experiment was conducted during the cabbage growing season of 2011-2012 at the Black Sea Agricultural Research Institute, Samsun, Turkey. Hybrids and parents were evaluated in a randomized block design with three replications. Measurements were performed for head weight, head diameter and head length to estimate mid parent and better parent heterosis in each hybrid. The direction and magnitude of mid parent and better parent heterosis among hybrids for all the head traits was found to be highly variable. The maximum and significant heterosis in... |

| Abstract: The objective of this work was to evaluate the potential per se of male-sterile and fertility-restorer lines of sweet sorghum (Sorghum bicolor), as well as to detail the heterosis manifested for some traits directly or indirectly related to ethanol production, accumulation rate, and predictability. Evaluations were performed for 20 genotypes, of which 4 are fertility-restorer lines (R), 3 are male-sterile lines (A), and 12 are experimental hybrids (H) resulting from the partial diallel cross between lines A and R, besides a commercial hybrid CV198 used as a check, in four harvest seasons. The experiments were carried out in the municipalities of Lavras and Sete Lagoas, in the state of Minas Gerais, Brazil. The measured traits were plant height,... |

| Current study is emphasizing on the estimation of heterosis for different yield attributing traits and adaptability of tomato hybrids. It was performed in the research area of VCRP, HRI, NARC Islamabad during 2018-2019. Crossing was completed among six parents followed by line × tester. The analyzed data depicted significant differences (P ≤ 0.01) among all the characters.Due to desirable high negative heterotic values hybrids Peto-86 × Nagina and Riograndi × Roma were found suitable for breeding early maturing hybrids. For plant height maximum positive heterosis was observed in Riograndi × Nagina, for no. of cluster/plant in Naqeeb × Roma, for traits like flower cluster-1, fruit cluster-1, fruit length & width and single fruit weight in Naqeeb ×... |
