Average phenotypic variation percentages found in the regenerants of P. dactylifera cv. Kashuwari and cv. Gulistan. The percentages are based on the sum of all the abnormal plants (578) appeared during the study period (2016 to 2018).
Percentage of variant phenotypes of P. dactylifera cv. Kashuwari and cv. Gulistan observed in the block I and block II. The percentages are based on the sum of all the observed plants in each block: block I, n = 27 and block II, n = 385.
Date palm variants observed during the survey of P. dactylifera cv. Gulistan: A) normal plant, B-C) excessive vegetative growth, D) abnormal frond/leaf growth, E) dwarf/inflorescence absent, F) fertilization failure, G) deformed offshoot, H) twisted inflorescence and I) high number of offshoots without inflorescence (cv. Kashuwari).
Mean variations for bunch physical characters in mother plant (MP) and tissue cultured (TC) date palm plants (Block I and II) of P. dactylifera cv. Kashuwari and cv. Gulistan: BL-bunch length, NS-number of spikelets, RFB-retained fruit per bunch, TNFB-total number of fruits per bunch.
Mean variations for fruit physical characters in mother plant (MP) and tissue cultured (TC) date palm plants (Block I and II) of P. dactylifera cv. Kashuwari and cv. Gulistan: FL-fruit length, FD-fruit diameter, FW-fruit weight, PW-pulp weight, PFR-pulp fruit ratio.
