L) JF - Horticultural Biotechnology Research JA - HBR VL - 4 IS - 0 SE - SPECIAL ISSUE ARTICLES DO - 10.25081/hbr.2018.v4.3492 UR - https://www.updatepublishing.com/journal/index.php/hbr/article/view/3492 SP - 35-38 AB - <p>Heterosis breeding is one of the most efficient tools to exploit the heterotic response for various useful traits. The Line × Tester mating design was undertaken with seven lines and three testers were evaluated along with twenty one hybrids in randomized block design to estimate the magnitude of heterosis for yield and its yield contributing characters. The best way to utilize heterosis in crop is to generate F₁ hybrids having maximum heterozygocity, thereby facilitating the identification and selection of hybrid vigor. The positive significant standard heterosis for fruit yield per plant was maximum with L₃ × T₁ (28.94%) followed by L₇ × T₃ (15.73%) and L₇ × T₁(15.10%) respectively. Some of the promising hybrids have showed desirable heterosis for plant height, number of fruits per plant,1000 seed weight, seedling shoot length, seedling root length and seedling dry weight.</p> ER -
