“…Kato et al (2009) and Singh (2013) also noticed that aerobic rice systems can reduce water use as much as 50 %. Bouman et al (2006) and Haryanto et al (2008) also observed that aerobic rice reduced water input without loss of yield. Yang et al (2005) found the higher water productivity in aerobic rice conditions than that of FT rice conditions.…”

A field experiment was conducted during rainy seasons of 2009 and 2010 at New Delhi, India to study the influence of varieties and integrated nitrogen management (INM) on methane (CH 4 ) emission and water productivity under flooded transplanted (FT) and aerobic rice (AR) cultivation. The treatments included two rice ('PB 1' and 'PB 1121') varieties and eight INM practices including N control, recommended dose of N through urea, different combinations of urea with farmyard manure (FYM), green manure (GM), biofertilizer (BF) and vermicompost (VC). The results showed 91.6-92.5 % lower cumulative CH 4 emission in AR compared to FT rice. In aerobic conditions, highest cumulative CH 4 emission (6.9-7.0 kg ha -1 ) was recorded with the application of 100 % N by organic sources (FYM?GM?BF?VC). Global warming potential (GWP) was significantly lower in aerobic rice (105.0-107.5 kg CO 2 ha -1 ) compared to FT rice (1242.5-1447.5 kg CO 2 ha -1 ). Significantly higher amount of water was used in FT rice than aerobic rice by both the rice varieties, and a water saving between 59.5 and 63 % were recorded. Under aerobic conditions, both rice varieties had a water productivity of 8.50-14.69 kg ha -1 , whereas in FT rice, it was 3.81-6.00 kg ha -1 . In FT rice, a quantity of 1529.2-1725.2 mm water and in aerobic rice 929.2-1225.2 mm water was used to produce one kg rice. Thus, there was a saving of 28.4-39.6 % total water in both the rice varieties under AR cultivation.

“…Variation for a given agronomic trait is not only determined by the variety, but also affected by environment and variety × environment (G × E) effects. [7] have studied Variety × environment interactions (GEI) in rice (Oryza sativa). GEI results from a change in the relative rank of variety performance or a change in the magnitude of differences between variety performance from one environment to another.…”

“…The yield of paddy rice is mainly determined by three components, panicle number per plant, grain number per panicle, and 1,000-grain weight (Hoshikawa, 1989;Kang et al, 2007;Haryanto et al, 2008). In the present study, panicle number per plant ranged from 8 ± 1.5 to 13 ± 1.3, and it was not correlated with grain number per panicle, because Luke Qasan and Germa Bala with the largest number of panicles per plant had the lowest number of grains per panicle, while, Sela Takhar, Sela Doshi and Pashadi Konar with the appropriate number of panicles per plant had the largest number of grains per panicle.…”

: In this study, we collected native aromatic rice cultivars from north, east and northeast of Afghanistan, and check cultivars from Japan, Thailand and India. We characterized some important agronomic characters such as plant height, panicle number per plant, grain number per panicle, 1,000-grain weight, grain length and grain width to find the desirable characters for breeding programs. Many of them were classified into tall culm rice according to IRRI index, but had thin and slender grain, and strong aroma which are favorable characteristics in Afghanistan and surrounding regions. The aromatic character was characterized by three methods, 1.7% KOH sensory test, gas chromatography-mass spectrometry-selected ion monitoring (GC-MS-SIM), and polymerase chain reaction (PCR) analysis. These three methods gave similar results. Six out of 10 Afghan native rice cultivars were aromatic and four non-aromatic. Among the check cultivars, Basmati 370, Jasmine 85, Izayoi, Oitakoutou and Jakouine were aromatic and Nipponbare non-aromatic. Improvement of aromatic and high yielding rice and reduction of plant height are the important objectives for rice breeding in Afghanistan. The results showed that Pashadi Konar from Afghanistan has the intermediate plant height, heavier 1,000-grain weight (32 g), longer grain (11 mm) and favorable aroma. Therefore, this cultivar may be a good source of aromatic rice germplasm in Afghanistan. To clarify the genetic nature of aroma in rice, we crossed non-aromatic cultivar Nipponbare with aromatic cultivar Jasmine 85, and examined the aromatic character in the F 2 generation by 1.7% KOH sensory test and PCR analysis. Non-aromatic and aromatic characters were segregated at a ratio of 3:1, showing that aroma is controlled by a single recessive gene.
