tailieunhanh - Estimation of heterosis for grain yield and yield components in pearl millet (Pennisetum glaucum (L.) R. Br.)
An experiment comprised of six male sterile lines, eight inbred testers of pearl millet, their 48 hybrids and two standard check (GHB-538 and GHB-558) was conducted at Regional Research Station, Anand Agricultural University, Anand, Gujarat in Kharif 2014 for studying the extent of hybrid vigour in F1 for grain yield and its components. The cross JMSA-9904 x AIB-15 showed highest and significant standard heterosis for total effective tillers, ear head girth, grain yield per plant and panicle harvest index. Among 48 hybrids studied, three hybrids namely JMSA-9904 x AIB-15, JMSA-9904 x AIB-30 and ICMA99555 x AIB-30 selected as best crosses since they expressed high standard heterosis over standard hybrid for many of the traits studied for high grain yield. | Estimation of heterosis for grain yield and yield components in pearl millet Pennisetum glaucum L.
