Abstract Panicle branching is one of the characters that can distinguish rice cultivar from another. Agricultural practices determined performance panicle branching. The trial aimed to study differences among ten lines based on cultivated good farming practices. Seven pure and three varieties were planted as genetic material in 4 replications. was conducted Bandung 2020 at an altitude 460 m asl...

in order to study the effects of foliar application of si (5/1000 ratio), k (2/1000 ratio) and zn (2/1000 ratio) on rice (cv. tarom hashem), an on-farm experiment carried out based on randomized complete block design with three replications in 2012. some traits such as paddy yield and yield components, neck blast disease and stem borer damage were evaluated. results showed that the effect of fo...

Rice blast is a destructive disease caused by Magnaporthe oryzae, and it has a large impact on rice production worldwide. Compared with leaf blast resistance, our understanding of panicle blast resistance is limited. The japonica landrace Jiangnanwan from Taihu Lake region in China shows highly resistance to panicle and leaf blast. In this study, three generations (F2:5, F2:6, F2:7) consisting ...

Sixty-nine cultivars of rice were examined for fourteen biometrical characteristics to study the degree genetic divergence, heritability and gain as a percentage mean, character relationship path coefficient analysis. Yield per plant reported highest estimate PCV GCV followed by total effective tillers plant, hundred seed weight, number filled seedsper panicle flag leaf length indicating that t...

line no. 4 was selected from local champ a rice of lord egan, based on pure line selection method, during 1992 to 1995. the mean yield of this line was 6342 and 6829 kgha-l in two regions of lord egan in 1996 to 1997. the yield of this line was 700-1500 kgha-l more than that of lord egan local rice. line 4 is more early maturing than the local rice with better marketability and quality. amylase...

Breeding programs for increasing spikelet number in rice have resulted in compactness of the panicle, accompanied by poor grain filling in inferior spikelets. Although the inefficient utilization of assimilate has been indicated as responsible for this poor grain filling, the underlying cause remains elusive. The current study utilized the suppression subtractive hybridization technique to iden...

Cytoplasmic male sterile (CMS) rice Zhenshan 97A (ZS97A) has been widely used in hybrid rice production in China. However, ZS97A suffers from serious panicle enclosure, which blocks normal pollination and greatly reduces seed production of hybrid rice. Little is known about the cause of panicle closure in ZS97A. In this study, it was found that the occurrence of cytoplasmic male sterility cause...

Foxtail millet (Setaria italica L.) is cultivated around the world for human and animal consumption. There is no suitable herbicide available for weed control in foxtail millet fields during the post-emergence stage. In this study, we investigated the effect and safety of the post-emergence herbicide tribenuron-methyl (TBM) on foxtail millet in terms of grain yield and quality using a split-plo...

Six parent diallel cross without reciprocal was studied to investigate the genetic behavior of different agronomic traits in rice. The analysis of Wr-Vr graph showed that panicle length, thousand grain weight and grain yield per plant did not follow the additivedominance model indicating epistatic gene action responsible for the expression of these traits. All other traits under the study were ...

Stomatal distribution is found to be an important trait of rice cultivars for increasing yield. A total of six rice cultivars, three from each of inbred and hybrid cultivars, were used to study stomatal distribution on the leaf epidermis and its influence on yield and yield attributing characters of rice during the Boro season. The hybrid cultivars exhibited superiority in respect of number of ...
