“…It was noted that the cultivar Binadhan-10 matured much earlier than other cultivars along with more grain filling period. The rice cultivars having higher grain filling duration have produced higher yield (Yang et al, 2008). Extension of grain filling duration provided rice plant with more climatic resources such as temperature and solar radiation for prolonged grain growth.…”

Yield reduction of rice is a severe problem due to the advent of increasing water scarcity and efficiency is relatively low. Physiological attributes and yield performance of high yielding (HYV) rice cultivars need to be assessed by minimizing water loss. Therefore, a glasshouse experiment was conducted in Bangladesh to investigate the impact of cultivars and water management on growth dynamics, biomass production, and yield and water productivity. Ten HYV boro (dry season irrigated) rice cultivars along with fivewater management systems were included in the study. The study revealed that cultivars Binadhan-10 had higher value of leaf area index (LAI), root dry weight along with moderate panicle length. Accordingly, the cultivar Binadhan-10 had a higher yield than all other cultivars because of the highest total dry matter (TDM), number of effective tillers hill -1 , and number of grains panicle -1 . Growth, TDM, and yield were increased with water application up to 8 DAD after which these factors declined with increasing water stress at 10 DAD. The crop grown at CS condition did not increase the yield, rather caused the wastage of irrigation water. The water productivity was the highest (0.252 t ha -1 cm -1 ) in 10 DAD treatments, obviously due to minimum water use but highest yield was observed in 8 DAD because of optimum use of water and non stress condition. Therefore, the present study was useful in the screening of the most efficient cultivars, which could be strongly recommended to rice growers to improve crop yield and reduce the use of water.

Rice is the most important food crop in Indonesia. Increase in production is needed due to population increase. Rice production in rainfed area is contributed the second after irrigated area. Rainfed condition requiring very early maturity (90-104 days) varieties. Rice anther culture can be applied to accelerate obtainment of doubled haploids (DHs) or pure lines needed in rice breeding. The experiment was aimed to obtain pure lines for developing very early maturing and high yielding rice varieties. Materials used for anther culture were F 1 s of Fatmawati/Kinamase, Inpari 1/Kinamase, Fatmawati/ Waseaikoku, Inpari 1/Waseaikoku, Fatmawati/IR71146, Inpari 1/IR71146, OM4495/Silugonggo, IR7146/Dodokan, and IR71730/OM1490. Anther culture media were N6 + NAA 2,0 mg/l + kinetin 0,5 mg/l for callus induction, MS+ NAA 0,5 mg/l + kinetin 2,0 mg/l for plantlet regeneration, and MS + 0,5 mg/l IBA for rooting. Putrescine 10 -3 M was added to callus induction and regeneration media. The results shown that calli forming green plantlet (CFGP) were ranged from 0.25 to 83.33%. Fatmawati/Kinamase gave the highest CFGP (245 calli), followed by Inpari 1/Kinamase (78 calli) and Fatmawati/ Waseaikoku (68 calli). Total green plantlets obtained were 2.038 plantlets. After plantlet acclimatization and greenhouse grow-out, we obtained 507 DHs. ABSTRAKPadi (Oryza sativa L.) merupakan komoditi pangan terpenting di Indonesia. Peningkatan produksi diperlukan seiring dengan peningkatan jumlah penduduk. Lahan sawah tadah hujan merupakan lumbung padi kedua setelah sawah irigasi. Kondisi lahan sawah tadah hujan memerlukan varietas-varietas padi berumur sangat genjah (90-104 hari). Teknik kultur antera dapat digunakan untuk mempercepat perolehan tanaman dihaploid (DH) atau galur murni dalam pemuliaan padi. Penelitian ini bertujuan untuk mendapatkan galur-galur murni yang akan digunakan dalam perakitan padi berdaya hasil tinggi dan berumur sangat genjah. Bahan tanaman yang digunakan untuk kultur antera adalah malai dari tanaman F 1 hasil persilangan Fatmawati/Kinamase, Inpari 1/Kinamase, Fatmawati/Waseaikoku, Inpari 1/Waseaikoku, Fatmawati/IR71146, Inpari 1/ IR71146, OM4495/Silugonggo, IR7146/Dodokan, dan IR71730/OM1490. Media kultur antera adalah N6 + NAA 2,0 mg/l + kinetin 0,5 mg/l untuk media induksi kalus, MS+ NAA 0,5 mg/l + kinetin 2,0 mg/l untuk media regenerasi, dan MS + 0,5 mg/l IBA untuk media perakaran. Putresine 10 -3 M ditambahkan pada media induksi kalus dan regenerasi. Hasil penelitian menunjukkan bahwa kalus yang menghasilkan tanaman hijau (KMTH) berkisar antara 0,25-83,33%. Persilangan Fatmawati/Kinamase memberikan KMTH tertinggi (245 kalus), diikuti oleh Inpari 1/Kinamase (78 kalus) dan Fatmawati/ Waseaikoku (68 kalus). Total tanaman hijau yang diperoleh adalah 2.038 planlet dihaploid, namun diperoleh 507 tanaman setelah planlet diaklimatisasi dan tanaman ditumbuhkan di rumah kaca. Evaluasi terhadap 100 DH dilakukan di lahan petani Ciranjang, Cianjur. Berdasarkan hari berbunga 50% (65 hari setelah semai), diperoleh 33 galur yang t...

“…In the Philippines, Yang et al (2008) evaluated the effect of temperature and solar radiation on the weight of grain filling rate and duration of grain filling in different rice genotypes and found a linear increase in yield with increasing temperature and solar radiation accumulated. In Bangladesh, Islam & Morison (1992) also evaluated the influence of solar radiation and temperature on the yield of rice, and found a positive relationship between grain yield and solar radiation during the reproductive and maturing stages.…”

-Irrigated rice sowing season and red rice competition are among the main factors affecting grain yield. The objective of this work was to evaluate the sowing date of irrigated rice and moments of application of the herbicide imazapyr + imazapic to control red rice management and irrigated rice grain yield. Eight experiments were performed at the following dates (09/30, 10/19, 11/08 and 12/01) for the 2010/2011 harvest season and (09/27, 10/17, 11/08 and 12/05) for the 2011/2012 harvest season. The treatments were: application of the herbicide imazapyr + imazapic at doses of 105+35 g ha -1 in pre-emergence (PRE); 52.5+17.5 g ha -1 in pre-emergence and 52.5+17.5 g ha -1 in post-emergence (PRE + POST); and 105+35 g ha -1 in post-emergence (POST), and a control without application and no weeding. The cultivar Puitá Inta CL was used and a randomized block design with four replicates. A joint analysis of the experiments was carried out. There was less emergence of red rice and higher grain yield of the irrigated rice at the early periods (09/30/10 and 09/27/11), with 10,578 and 8,653 kg ha -1 , respectively. At the end of the season (12/01/10 and 12/05/11), there was greater reduction of the red rice seed bank. Sowing at the beginning of the recommended period provided more irrigated rice grain yield. The application of imazapyr + imazapic at a dose of 52.5+17.5 g ha -1 in PRE + 52.5+17.5 g ha -1 POST, and 105+35 g ha -1 only in PRE and POST was effective in the control of red rice.
