dc.description.abstract | Ma wee is a group of traditional rice accessions with abiotic stress tolerance. Ma wee
is grown only during Maha season due to the short-day requirement for flowering.
This experiment was conducted to determine the response of selected Ma wee
accessions to planting date (PD) during Maha season on agronomic and yield
characters. PDs were September 15, 30, October 15, and 30, 2021 with a photoperiod
ranging from 12:09 to 11:53. Maha ma wee accessions (8541, 8543), one Ma wee
samba accession (4561), and an improved variety Bg 300 were planted in pots in a
complete randomized design with five replicates under greenhouse conditions. Yield
and agronomic characters were evaluated. Days to fifth leaf (DFL), Plant height at the
fifth leaf (HFL) and Height at flowering (HF), Grains per the first panicle (GPP), and
effective tillers at harvest (ETH) were affected by PD. Days to flowering (DF) at PD1
were lesser (124,, 135 and 136) in Ma wee in contrast to other PDs while DF of Bg
300 was not affected. GPP was affected by PD as the plants of PD1 produced the
highest GPP in all genotypes (225, 269, and 286). The plants of other PDs produced
low GPP (from 178 to 64). The above results indicate the optimum PD requirement
of Ma wee for incorporation in breeding programmes. | en_US |
