The researchers studied how different combinations of sesame plants can produce higher seed yields. They crossed 28 hybrids from eight parent plants to see which combinations gave the best results. They found that some crosses produced significantly higher seed yields than the standard parent plant. The crosses AT 347 x G.TIL 4, AT 377 x AT 396, AT 396 x AT 404, and AT 376 x AT 377 showed the most promise, with up to 22.86% higher yields compared to the standard parent. These findings suggest that these specific crosses could be used to improve seed yield in sesame through heterosis breeding programs.
