Heterosis for Grain Yield and its Important Components in Aromatic Rice (Oryza Sativa L.)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2019, Vol 9, Issue 2
Abstract
Eight genotypes consisting three Basmati varieties viz, Basmati Kasturi, Basmati 370 and Basmati with five Manipur scented rice landraces viz, Chakhao Poireiton, Chakhao, Chakhao Amubi, Ching Chakhao and Chakhao Angangba were crossed in 8X8 diallel fashion without recieprocal producing twenty eight F1 hybrids and were evaluated to estimate mid parent heterosis for eleven yield contibuting characters. The best crosses which have the highest magnitude of mid-parent heterosis for grain yield per plant were Chakhao Poireiton x Chakhao Amubi(79.77), Chakhao Amubi x Ching Chakhao(79.11) and Chakhao Poireiton x Basmati(59.56). Basmati 370 x Ching Chakhao (-23.29)showed high magnitude of negative heterosis for plant height at maturity, Basmati x Ching Chakhao showed highest magnitude of positive heterosis for total number of spikelets per panicle (49.23) and total number of filled grains per panicle (65.77).
