Morphological characterization of rice accessions - off planting season 2012

Morphology-Off Season 2012

Accessions of Malaysian rice germplasm conserved at MARDI possess a wide genetic diversity useful for the development of new rice varieties. Morphological characterization data plays an important role to identify potential rice accessions for plant breeding. MARDI conducts the morphological characterization of its accessions during regeneration. This dataset contains information collected during the regeneration of rice accessions in the off planting season of 2012.

Caractéristiques observées


  • Secondary Branching

    To observed the secondary branching bearing the spikelets. Time: near maturity

  • Maturity

    Maturity is recorded as the duration in days from seeding to the time when more than 80% of the grains on the panicles are fully ripened. When that information is not available, maturity is estimated by adding 30 days to the duration from seeding to full heading. Time: at maturity

  • Leaf Senescence

    The leaves below the flag leaf are observed at the time of harvest for their retention of greenness.

  • Culm Strength

    To observed lodging resistance. Culm strength is first rated after panicle emergence by gently pushing the tillers bank and forth a few times. The test gives some indicators of culm stiffness and resilience. Final observation at maturity is made to record standing position of plants. Time: after flowering up to maturity

  • Panicle Shatterring

    The extent to which grains have shattered from the panicle. Time: at maturity

  • Panicle Threshability

    The matured panicle is grasped by hand and a slight rolling pressure is applied with the palm and fingers. The observation is based on the extend of grain removal. Time: at maturity

  • Panicle Exertion

    The exsertion of the panicle above the flag leaf sheath after anthesis. Time: near maturity

  • Panicle Axis

    The axis of the panicle is observed by position of the panicle in the entire plot. Time: at maturity

  • Apiculus Color

    Apiculus color is determined by eye inspection. Time: at maturity

  • Awn Color

    Awn color is determined by eye inspection. Time: at maturity

  • Awning

    The presence of awn recorded based on awning characters. Time: after full heading

  • Ligule Length

    Ligule length is measured in milimeters from the base of the collar to the tip. Its absence is denoted by a blank. Time: late vegetative stage

  • Ligule Color

    Ligule color is determined by eye inspection. Time: late vegetative stage

  • Leaf Blade Color

    Blade color is determined by eye inspection and using green color code by IRRI. Time: late vegetative stage

  • Basal Leaf Sheath Color

    Color of the outer surface of the leaf sheath done by eye inspection. Time: early to late vegetative stage

  • Auricle Color

    Auricle color is determined by eye inspection. Time: late vegetative stage

  • Number of days from seeding to 50% heading

    The days are counted from the date on which sowing on the wet seedbed was made to 50% panicle heading averaged from the whole plot

  • Ligule Shape

    The shape is measured by eye inspection and based on the diagram given in the Rice Descriptors List. Time: late vegetative stage

  • Collar Color

    Collar color is determined by eye inspection. Time: late vegetative stage

  • Flag Leaf Width

    Width is measured at the widest portion of the blade on the flag leaf on the main culm. Time: late vegetative stage

  • Flag Leaf Angle

    Leaf angle is measured near the collar as the angle of attachment between the flag leaf blade and the main panicle axis. Time: after heading

  • Flag Leaf Length

    Flag leaf length is measured in centimeters on the main culm. Time: late vegetative stage

  • Leaf Angle

    The angle of openness of the blade tip is measured against the culm on the leaf below the flag leaf. Time: prior to heading

  • Leaf Blade Pubescence

    Blade pubescence is measured by touching on the leaf surface area. Time: late vegetative stage

  • Leaf Length

    Leaf length is measured in centimeters from the topmost leaf blade below the flag leaf on the main culm. Time: late vegetative stage

  • Leaf Width

    Width is measured at the widest portion of the blade on the leaf below the flag leaf on the main culm. Time: late vegetative stage

  • Stigma Color

    Stigma color is determined from blooming spikelets (between 9 a.m. and 2 p.m.) with the aid of a hand lens. Time: at maturity

  • Grain Length

    Grain length is measured in milimeter as the distance from the base of the lowermost sterile lemma to the tip (apiculus) of the fertile lemma or palea, whichever is longer. In the case of awned varieties, the grain is measured to a point comparable to the tip of the apiculus. Time: at maturity

  • 1000 Grain Weight

    A random sample of 100 well-developed, whole grains dried to 13% moisture content is weighed on a precision balance to give the 100-grain weight. Time: at maturity

  • Spikelet sterility

    Spikelet sterility readings are obtained from counts of well-developed spikelets in proportion to total number of spikelets on five panicles. Time: at maturity

  • Sterile Lemma Length

    Measurement is made on each of the sterile lemmas.

  • Grain Width

    Width of grain is measured in milimeters as the distance across the fertile lemma and the palea at the widest point. Time: at maturity

  • Panicle Length

    Length of panicle is measured in centimeters from the base to the tip of the panicle. Time: near maturity

  • Panicle Type

    Panicles are classified according to their mode of branching, angle of primary branches, and spikelets density. Time: near maturity

  • Culm Angle

    Culm angle readings are based on plants grown in the entire plot. Time: after flowering

  • Culm Diameter of Basal Internode

    Data are taken in milimmeeters from the outer diameter of the culms measured at the midportion of the culm. Time: around flowering period

  • Culm Length

    Culm length is measured in centimeters from ground level to the base of the panicle of the main culm. Time: after heading

  • Culm Number

    Culm number is recorded after full heading as the total number of grain-bearing and non-bearing tillers. Time: after heading

  • Culm Internode Color

    The color of the outer surface of the internodes on the culm. Observed by eye inspection. Time: after flowering

  • Sterile Lemma Color

    When the terminal spikelets are approaching maturity. The color detemined by eye inspection. Time: at maturity

  • Lemma and Palea Pubescence

    Pebescence of the hull. Time: at maturity

  • Lemma and Palea Color

    Determined when the terminal spikelets are ripened. Observed by eye inspection. Time: at maturity
