Genetic Analysis for Panicle Characters in Diallel Cross of Rice
An experiment was carried out to study the genetic components for eight panicle characters in rice using an 8-parent half diallel cross excluding reciprocals during Transplant Aman season, 2003. The parental genotypes used in the study were BRRI dhan29, BR4828-54-4-l-4-9, BRR1 dhan28, 1R8, Amol3, 1R6561038-2-4-2-6-3, Minikit and ZhongYu7, which were chosen for their diversity in panicle charact...
متن کاملHeterochronic development of the floret meristem determines grain number per spikelet in diploid, tetraploid and hexaploid wheats.
BACKGROUND AND AIMS The inflorescence of grass species such as wheat, rice and maize consists of a unique reproductive structure called the spikelet, which is comprised of one, a few, or several florets (individual flowers). When reproductive growth is initiated, the inflorescence meristem differentiates a spikelet meristem as a lateral branch; the spikelet meristem then produces a floret meris...
متن کاملStudy of Genetic Variation in Wild Diploid Wheat (Triticum boeoticum) from Iran Using AFLP Markers
Little information is available regarding genetic variation in wild wheat relatives from Iran. In this study, genetic diversity of 36 populations of wild einkorn wheat, Triticum boeoticum, was studied using amplified fragment length polymorphism (AFLP) primer combinations. Seventeen AFLP primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...
متن کاملSpikelet and Floret Naming Scheme for Grasses with a Spike Inflorescence
Effective schemes to name uniquely and d e h e parts of grass plants allow researchers to communicate results of their experiments accurately and precisely. Naming schemes for vegetative parts of grass plants have been developed; however, no system exists to name uniquely parts of the inflorescence. In this report, we present a method to extend existing systems to name parts of grass spikes. Sp...
متن کامل‘Two‐floret spikelet’ as a novel resource has the potential to increase rice yield
Yield in rice (Oryza sativa) is determined by three major components: panicle number per plant, grain weight and grain/ spikelet number per panicle (Zhou et al., 2015). Grain number per panicle is one of the main targets and mainly results from the number of spikelets. Traditionally, rice breeders have focused on the improvement of spikelet number per panicle and rarely focused on the number of...
