At this stage, streaks are more clearly visible on the lower surface of the leaf than on the upper one. The distribution of streaks is variable. Sometimes they are most numerous near the edge of the left side of the leaf. At other times they are equally numerous on both sides of the leaf, and more or less evenly distributed. Frequently they are densely aggregated in a band several cm wide on one side or both sides of the mid-rib, becoming less numerous towards the edge of the leaf. Streaks may be so numerous that every cm2 of leaf surface bears one or more. There is considerable variation in the length of individual streaks on a given leaf, and they frequently overlap to form larger, compound streaks. 2 cream cream 2 4 1/3-2/3 discoloured erect 5 Bioversity International Rhiannon Crichton BlkLfStrkLfFrStg1_Date_ymd purple 5 green yellow 4 Bioversity International/IITA temp51 Inge Van den Bergh/Danny Coyne margins curved inward 3 Rhiannon Crichton Bioversity International BnchHndNum_Ct_Hnd pseudostemFreshMass_Meas_g pseudostem_fresh massFreshPseudostem Sebastien Carpentier KU Leuven Rhiannon Crichton Bioversity International PStmHt_M1_cm 3 intermediate leafAreaRatio_Comp_unitless areaRatio Sebastien Carpentier KU Leuven areaPlant_per_areaTot 5 light green Inge Van den Bergh/Danny Coyne temp48 Bioversity International/IITA FstExtDiSmptFW_Date_ymd Rhiannon Crichton Bioversity International HndFrtAvgNum_Ct_Frt Bioversity International Rhiannon Crichton ** 2 like extremely 5 wide with erect margins 2 rootToPlantMassRatio_Comp_unitless massDryratioRoot KU Leuven Sebastien Carpentier relativeRoot_dry Rhiannon Crichton temp11 Bioversity International Selection criteria for genotype that was ranked third lowest by male respondents during preference scoring exercise Bioversity Noel Madalla Rachel Chase Bioversity International FrtCvShp_Est_1to6 2 pink-purple to red IITA HelicoNumSlWt_Comp_Nema Danny Coyne purple to blue 3 Bioversity International CmpdTplLbCl_Est_1to16 Rachel Chase temp41 Bioversity International Rhiannon Crichton Rachel Chase Bioversity International MlRchsApp_Estm_1to7 Rhiannon Crichton PulpDiam_M_mm Bioversity International AvgWvlLvBdLgt_M_µM Tendo Ssali IITA PMargWing_Est_1or5 Rachel Chase Bioversity International KU Leuven waterLossSystPerLeafArea_Meas_mlcm2 waterLossSystem_per_Area Sebastien Carpentier IITA-BTI FngUnSmshdPlpSmth_Est_1to5 Allan Brown/Guillaume Bauchet (temp.)

Percentage of plants with a splitting pseudostem base caused by Fusarium wilt - computation Damage percent X-average The average percentage of damage in the whole corm (the inner corm and the outer corm) caused by weevils. Average percentage damage to the corm caused by weevils Water loss - measurement Weighing of water loss though plant between timepoints (refer to experimental metadata) Overall fruit pendulance quality The overall estimation fruit pendulance on a bunch pendulantfruit Finger pendulance quality Force required to obtain deformation, penetration or rupture of the banana BoiPlantnFirm Boiled plantain Firmness Boiled plantain Firmness Calculate the ratio w/y, i.e. the broadest width of the male bud to the total length of the male bud. Do not measure the dimensions along the bud but rather on a projection/outline of the bud (e.g. trace the outline of the bud on paper) and use ruler or measuring tape Male bud shoulder - computation Nematode stage - estimation Identify the nematode stage, using the options. Body length Banana weevil adult body length The length of a banana weevil adult body, from the head to the tip of the abdomen. Percentage of dead roots Percentage of dead roots The percentage of all roots in a standard-size excavation of 20 x 20 x 20 cm extending outwards from the corm of the plant that are dead. Stickiness in hand MatStickT Matooke stickiness Matooke mechanical textural attribute relating to the force required to remove material that sticks to the mouth The weight of all the hands of the bunch, excluding the rachis. totalfingerweight Total finger weight Combined weight Damage percent X-lower-inner Percentage damage to lower cross-section inner corm caused by weevils The amount of damage to the inner corm (central cylinder) lower cross-section, assessed by percentage of tunnels caused by weevils. Focus group discussion with female respondents, to discuss selection traits of genotype that was ranked third highest in preference ranking exercise Focus group discussion for third ranked traits with female respondents Non-harvest density - computation Calculate as: the Plant density multiplied by the Non-harvest proportion, e.g. 1,667 * 0.08 = 133. Calculate as: the sum of the number of values for Date of planting. Number of plants planted - computation Open question leaves/week Black leaf streak disease development time - computation Calculate as: the time elapsed between the Date of tagged leaf presenting black leaf streak disease symptoms at Foures stage 6 and the Date of tagged cigar leaf unrolling at stage B, e.g. 24/06/2014 - 24/03/2014 = 92 days. wing presence/absence Shape of the longitudinal curvature Fruit shape of curve Shape of a fruit (finger) in the middle of the bunch **subsume Sweetness tasting method Put a part of the sample in the mouth and evaluate the intensity of taste of sweetness Number of fingers in outer whorl numfingersouterwhorl2nddistalhand Number of fingers in outer whorl of 2nd-most distal hand The number of fingers in the outer whorl of the second-most distal hand Focus group discussion for third lowest ranked traits with male respondents Focus group discussion with male respondents, to discuss selection traits of genotype that was ranked third lowest in preference ranking exercise The average thickness of the peel of a finger. avepeelthickness Average thickness of the peel Average finger peel thickness Extent of internal discolouration in corm of tallest sucker caused by Fusarium wilt - estimation The extent to which vascular discolouration extends up the pseudostem of the tallest sucker should be determined by making cross-section cuts, from the base of the pseudostem upwards, and examining the internal tissues following each cut. The point at which discolouration is no longer visible should be noted and the distance from this point to the pseudostem base recorded. bud shape scale (1 to 5) Count from 100 ml of soil sample Number of nematodes (Meloidogyne spp.) per unit fresh root weight - method Species present The nematode species found in the banana plant root sample. Nematode species kg/plant/y BD colour chart A - 1996 The average weight of a banana weevil adult body. Average body weight Banana weevil adult average body weight Calculate as: the Bunch weight divided by 1,000, multiplied by the Annual crop cycle proportion, multiplied by the Plant density, e.g. (50 / 1,000) * 1.09 * 1,667 = 90.85. Potential annual yield - computation Visually observe the fruit pulp colour and select the option in the colour chart that is most representative. The recommendation is to collect this data from six fingers in total - three fingers in the middle of the outer whorl from the second hand and from the second-most distal hand.
